Reads Text File Consisting Of Words From A To Z

Apr 12, 2015

I am writing a program for my college class that does the following:

Reads a text file that consists of words from a-z. The content read from the file is displayed in the JTextArea, while the user can filter the search results based on what they input. For example, if the user enter's "a" then the JTextArea is updated with all words that start with the letter "a" only. Also the user can enter a substring or the whole word and the respective result will be only the words that match the user's input.

The Problem and question I have is what would be the best way to go about filtering a file of about 27,000 words based on user input. I tried using an arraylist but the problem is it took forever to update the JTextArea, which is not good. Also I am new to using JSwing so I may not be aware of a component that would make this easier.

Here is the code:

Note: the question lies within the actionPerformed method.

package source_code;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;

Java Program That Reads Array From Text File

Mar 19, 2015

I was wondering if it's possible to do this: I want to build a java program that reads a java array from a text file.

Then I want to read it, and output it in a different format.

The reading and out is easy - as text.

But how can I incorporate the read text in to a java valid array in my program, which I can use?

Is this even possible?

Placing Randomly Chosen Words From Text File Into 2D Array

Apr 5, 2014

I have an assignment for college that involves placing randomly chosen words from a text file into a 2-d array. I have nearly completed ithowever I am having difficulty with a list of string type.What I have done so far is below,

import java.util.Arrays;
import java.util.List;
import java.util.ArrayList;
import java.io.*;
import java.lang.Math;
 
[code]....

when I try to run an instance of the program(using BlueJ) I get an error saying there is a null pointer exception at line 35 which is wordsForGrid. add (puzzleWords.get(pos));

I am thinking that this is related to the fact that at this line in the loadWordsFromFile method List <String>words=new ArrayList<String>(); I could not create an empty list of string type, i.e List<String>words = new List<String>();

Is this correct? Or am I looking in the wrong place. The textfile I am using contains over 6000 words on a separate line for each if that makes any difference.

Application That Reads In A Line Length Followed By Individual Lines Containing Text

Jan 9, 2015

I'm currently learning Java and have been set an assignment that requires me to do the following:

Write an application that reads in a line length followed by individual lines containing text. No input line will be longer than the read in line length. In the text lines each word will be separated by a single space. The lines of text to be reformatted and then output so that the output lines of text have straight left and right margins. The last printing character in each line will be at character position (line length). In the text output the character '.' is to be used to represent the space character.

Page 2 - Gyazo - 470cf689a3126b7ab6c64bb14ae80a0d.png

I'm trying to take this task on, but I'm unsure as to what exactly I'm supposed to do with part of it. For one of the methods I need to "work out how many extra spaces will need to be added to make the line width characters long.", how would I go about doing this?

Use JTextarea To Display Text And Then Prompt Users To Type In Certain Words

Nov 9, 2014

So currently I am trying to use a JTextarea to display text and I then prompt users to type in certain words. I have a few problems that I have encountered. Firstly when I use setText and then if I say setText again after that it erases the previous text that was set. Ideally I want to set text once per line in my whenever a certain task is fulfilled. For example if the text says enter y/n, I want the program to go to the next line once I say y or n. Another problem of course is when I setEditable to true I can edit the whole textArea. I just want to be able to edit the line which I am currently at. Is there anything that I can use that mimics the ACM console program, or even the console down below in most IDE's where everything appears to be done line by line?

Also here is an example of what I am trying to do, along with comments:

Java Code:

console.setText("Math is good!");
console.setText("What is 2+2?: "); //using getText gets the whole line, I want
//everything checked after the colon. That is where the input will be
if(line==4){
console.setText("That is correct");
}
else {
console.setText("That is incorrect");
}
//previous text lines are overriden with new ones. I don't want that, nor do I want to be able to edit the
//whole JtextArea mh_sh_highlight_all('java');

A JtextArea is just not getting the job done.

Read Input File And Create Output With Anagram For Words In File

Sep 24, 2014

Well my code is supposed to ask for an input file and then (ex: input.txt), read the input file and create an output.txt file with the anagram for the words in the file. Also it should be displayed on the screen. However my code doesn't display the anagram on screen or the output file!

Heres is the code:

import java.io.*;
import java.lang.*;
import java.util.*;

/* This program will read a file given by the user, read the words within the file and determine anagrams of the given words. If the file that the user inputs is empty, then the program will output "The input file is empty."
* The program will read the file line by line, counting the total number of words read. If there are more than 50 words, "There are more than 50 words."
* will be printed, and the program will terminate. After each line is read, the words in the line will be separated,punctuation characters will be removed, and upper case characters will be switched to lower case.
* If any word is larger than 12 characters, that word will not be considered in the total amount of words in the file and it will not be sorted.
* After each word is read, the letters will be sorted and stored into an array containing each
* word's 'signature'. After all the words have been read, words will be printed to the output file on the same line based upon their signature.
*/

public class Anagram {
//Creating constants for maximum words in file and maximum chars in word
public static final int MAX_CHARS = 12;
public static final int MAX_WORDS = 50;

Program That Accept Words And Their Meanings Or Display List Of Words In Lexicographical Order

Apr 15, 2015

Write a menu driven program that either accepts words and their meanings, or displays the list of words in lexicographical order (i.e. as in a dictionary). When an entry is to be added to the dictionary you must first enter the word as one string, and then enter the meaning as separate string. Another requirement - from time to time words become obsolete. When this happens, such word must be removed from the dictionary.

Use the JOptionPane class to enter the information.

Use the concept of linked list to carryout this exercise. You will need at minimum the following classes:

- A WordMeaning class that hold the name of a word and its meaning.
- A WordMeaningNode class that creates the node of information and its link field.
- A WordList class that creates and maintain a linked list of words and their meanings.
- A Dictionary class that test your classes.

For the output, the program should produce two scrollable lists:

- The current list of words and their meanings.
- The list of the deleted words. You need not list the meanings, just the words.

So far, I have everything coded except for the remove method, and I am not sure how to code that. I coded the add method already, but now I don't know where to begin with the remove method in my WordList class. My classes are below.

WordMeaning Class:

public class WordMeaning {
String name;
String definition;
WordMeaning(String t, String d) {
name = t;
definition = d;

String Manipulation - Extract Substrings Consisting Of First N-4 And Last Three Characters

Feb 18, 2014

I do have a quick question about string manipulation. You see I've been given a simple exercise that involves asking the user to input a number between 1,000 and 999,999 and displaying the result. Simple enough, but the caveat is that if the user keys in the comma, say 24,000 instead of 24000 for example, the program is not to display the comma. I don't see how to do this without an 'if' statement. The book says the 'if' is not necessary but does offer this hint: "Read the input as a string. Measure the length of the string. Suppose it contains n characters. Then extract the substrings consisting of the first n-4 characters and the last three characters."

What good is n-4 going to do if the string's lengths varies?

Here's what I have written thus far:

import java.util.Scanner;
 public class P13
{
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
System.out.print("Please enter a number between 1,000 and 999,999: ");

How To Make A Text File Only Use Lines In A Text File Beginning With A Certain Letter

Mar 15, 2015

I have a program that reads lines of text, but some of the lines of text aren't applicable and break the program. I'd like to put a letter in front of the lines in the .txt file I want to use, such as a #.

I need to make an if loop that'll check for the first letter on the line being #, and use the line in the program if true and skip if false. I'm guessing a boolean variable would be useful here to be true or false depending on the presence of #, but I don't know how to only read the first letter of each line, how can I do this?

String Split Method - Return Array Of Strings Consisting Of Substrings Splitted By Delimiters

Sep 28, 2014

I am having a problem with the following code. It compiles and runs fine however my output is wrong.

public class SplitString {
public static void main(String[] args) {
String[] string1 = split("ab#12#453", "#");
String[] string2 = split("a?b?gf#e", "[?#]");
for (int i = 0; i < string1.length; i++) {
System.out.print(string1[i] + ",");

[code]....

The split method in the String class returns an array of strings consisting of the substrings split by the delimiters. However, the delimiters are not returned. Implement the following new method that returns an array of strings consisting of the substrings split by the matching delimiters, including the matching delimiters.public static String[] split(String s, String regex)For example, split("ab#12#453", "#") returns ab, #, 12, #, 453 in an array of String, and split("a?b?gf#e", "[?#]") returns a, b, ?, b, gf, #, and e in an array of String.

Pickup Selected Text File And Read Line By Line And Output Text Into Visual Text Pane

Dec 12, 2014

I am checking how to do following task.

01. pickup the selected text file and read the line by line and output the text in to visual text pane.

what i did:.

01. I wrote code that read the text file and output in to jave console/ also some of the interface.

the code read txt file:

Java Code:

String fileName = "C:/Users/lakshan/Desktop/lawyer.txt";
File textFile = new File(fileName);
Scanner in = new Scanner (textFile);
while(in.hasNextLine()){

[code]....

so it will read any text file dynamically and output to the text pane in interface. I think scanner code must be execute after the select the file from the browser and set the scanned result in to variable. then later out put the var as string in some jswing component?

Write Application That Reads Five Integers

Jun 12, 2014

Write an application that reads five integers, determines and prints the largest and smallest integers in the group. Use only the programming techniques you learned in this chapter. (which means: use only if statements and the equality and relational operators).If I want to solve this I will write nested if statements for every probability like the following.The probability: the first integer is the largest and the fifth integer is the smallest:

1>2>3>4>5
1>2>4>3>5
1>4>3>2>5
1>4>2>3>5
1>3>4>2>5
1>3>2>4>5

And so on for every probability.

Write A Java Program That Reads 5 Integers

Oct 9, 2014

Project is due before midnight eastern time (3 more hours). I have been working on this all day, we have not learned arrays or anything and just started 'for' loops. I don't really know how to implement that system yet. However, he wants us to check all the possible handwritten math ways of doing this. I have tried but I cannot return my numbers beside the card.my program only prints the type and I still have more cases to add as well..

QUESTION: Write a Java program that reads 5 integers, each of which is in the range of 1 and 13 representing a simplified poker card with no suit. Your program should then print the ranking of the hand with card number(s) beside the ranking. The rankings to determine are Four of a Kind(4 of the 5 cards of the same rank), Full House(3 of the 5 cards of the same rank, and 2 cards of another rank), Straight(5 cards of sequential rank), Three of a Kind(only 3 cards of the same rank), Two Pair(2 cards of the same rank, 2 cards of another rank, and no card of either rank), One Pair(only 2 of 5 cards are of the same rank), and High Card(no two cards of the same rank). Some sample runs are:

input: 2, 3, 2, 2, 2; output: Four of a Kind(2)
input: 2, 3, 2, 3, 2; output: Full House(2, 3)
input: 2, 3, 4, 5, 1; output: Straight(5)
input: 1, 13, 11, 10, 12; output: Straight(1)

Write A Program That Reads From User Several Lines Of Input

Mar 24, 2014

a. Assume that we have a list of employees' names of a company and their ages. Write a program that reads from the user several lines of input. Each line includes an employee's name and his/her age (as an integer). The program should calculate and print the following:

- The average age of all employees (rounded to 2 decimal places).
- The oldest employee and his/her age.

Hints:

You could assume that the user will insert valid data and at least one employee.
You could assume that the oldest employee is only one person.
User could stop the program via entering the word "end" as an employee's name.

Sample Input and Output: In each line, insert an employee's name and his/her age To halt the program, insert "end" as an employee's name

Adam 30
Tom 41
Ted 45
Karl 30
end

The average age of all employees is 36.50.The oldest employee is Hisham whose age is 45

Write A Java Program That Reads A Positive / Non-zero Integer As Input

Aug 1, 2011

Write a Java program that reads a positive, non-zero integer as input and checks if the integer is deficient, perfect, or abundant.

A positive, non-zero integer, N, is said to be perfect if the sum of its positive proper divisors (i.e., the positive integers, other than N itself, that divide N exactly) is equal to the number itself. If this sum is less than N, the number is said to be deficient. If the sum is greater than N, the number is said to be abundant.For example, the number 6 is perfect, since 6 = 1 + 2 + 3, the number 8 is deficient, since 8 > 1 + 2 + 4, while the number 12 is abundant, since 12 < 1 + 2 + 3 + 4 + 6.

SAMPLE OUTPUT:

1.)Input N: 5

5 is deficient.

2.)Input N: 6

6 is perfect.

3.)Input N: 18

18 is abundant.

Read Text File Into Object Array And Creating Random Access File

Dec 8, 2014

I am working on a project that requires me to build a database with random access file, representing products, the base product contains a name (about 30 characters), a price (double), and a quantity (integer). I have worked on this project for probably 15+ hours and have tried so many things and feel like I've barley made any progress...

The part i am really struggling with is taking the data from the text file and creating an object array with it using the product class. Once ive accomplished that, i have to use that data to create a random access file with the data.

Here is the base Product class that must be used to create the objects for the array.

public class Product
{
public String pName;
public String stringName;
public double price;
public int quanity;

[Code] .....

And then here is the data from the text file that i must extract to use to create product objects.

Dill Seed,938,34
Mustard Seed,100,64
Coriander Powder,924,18
Turmeric,836,80
Cinnamon (Ground Korintje),951,10
Cinnamon (Ground) Xtra Hi Oil (2x),614,31
Cinnamon (Ground) High Oil (1X),682,19

These continue for about 40-50 entries, they are not separated by a blank line though i had to add those so it would display correctly, each entry is on its own line with name separated with spaces, then price after a comma, then quantity after the second comma.....
