Read Line From File And Save First String As Word And Remaining As Meaning

Jul 6, 2014

I have written the code to read the line from file and save first string as word and and remaining string as meaning..

E.g.: innovation a new method, idea, product, etc.

word = innovation

meaning = a new method, idea, product, etc.

In my code there is no error and have a mistake what it is means first assigning word is ok and while saving meaning ..it saves like

{

Java Code:

import java.io.BufferedReader;
import java.io.FileReader;
public class Dil{

Read Line Of Input For A File - String Tokenizer

Jan 27, 2015

So I'm having a problem with the .hasMoreElement() method. I try to read lineOfInput for a file which contains:

StringTokenizer inputField = new StringTokenizer(lineOfInput, ",");
while(inputField.hasMoreElements()) //for each fields is a line

firstName = inputField.nextElement().toString();
email = inputField.nextElement().toString();
phoneNumber = inputField.nextElement().toString();
level = Integer.parseInt(inputField.nextElement().toString());

How To Save A Word In A Text File

Apr 19, 2014

This part of the code searches for every word in the text file and saves it to an ArrayList. It searches for the word if its valid of not.How can I offer a list of similar words when the word that the user inputs is not in the dictionary. Also I want it to prompt the user to accept the word or enter a replacement that gets saved in the dictionary.

package spellChecker.project1;
 
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

Read Text File Into Array Ask User To Save File And Print Data

Jul 14, 2014

New to programming. Am supposed to create a program that reads a text file (of integers) and computes a series of computations on these integers. I don't have the code for the integers in my code yet, (i know how to do those), but am struggling getting the array to simply print in the print writer. I have the user select a text file, read the file with a scanner, and then save the computations done from my code into another file. specifically, the problem is as follows: Write a program that uses a file chooser dialog to select a file containing some integers. The file contains an integer N followed by N integers. The program then uses a file chooser dialog to let the user specify the name and location of an output file to write results to.The data written to the output file will be as follows

(1) The original list of N numbers from the input file,
(2) The original list of N numbers printed in reverse order of how they appear
in the input file.
(3) The sum and average of these numbers,
(4) The minimum of all the numbers,
(5) The maximum of all the numbers.

[import java.io.File;
import java.io.IOException;
import java.io.PrintWriter;
import java.io.Writer;

Output Contents Of Input File In Alphabetical Order One Word Per Line

Jun 22, 2014

I am having a lot of trouble with this lab. basically I have to make a text processor to read in code put it into a file and output the contents of the input file in alphabetical order one word per line. I have to reference the string varaibles input_filename and output_filename.

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Scanner;
import java.io.File;
public class TextProcessor {

[Code] ....

these are the guidelines to said lab:

1. In the main method define two Strings called input_filename and output_filename. I will be setting these Strings to my own file names for testing your code, so make sure you get these variable names correct, and that you use them properly in the following steps.
2. Read in the text contents of the file referenced by input_filename.
3. Split the contents of the input text into separate tokens, using whitespace as a delimiter.
4. Lower case the tokens.
5. OPTIONAL: remove punctuation
6. Alphabetize the tokens.
7. Using output_filename, write the alphabetized tokens to an output file, one token per line.
8. Be sure to close file streams - no resource leaks!
9. Use methods to separate functionality in your program where possible

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?

Read File And Input Each Line Of File Into Array

Mar 21, 2015

I am trying to read a file and input each line of the file into an array. I have not set the array size as I was hoping to fill the array using a while loop. Unfortunately the scope of the array does to work inside the while loop so I am being told that the array 'students' has not been initialised even though it has just outside of the while loop. Is it possible to do what I am trying to without having the array initialised in the while loop as surely the array will be reset every time if it was in the while loop? Here is my code:

public static void students(String file) throws FileNotFoundException {
try {
File studentInfo = new File(file);
Scanner input = new Scanner(studentInfo);
String[] students;

I/O - Read 11 Values From A Text File / Each Value On Separate Line

Mar 26, 2014

So I'm trying to read 11 values from a text file, each value on a separate line. The first value I use as loop control to run through calculations on the other ten and finally output both the numbers and the calculations to the console and an output file. I'm not getting a compiler error or a runtime error but my loop seems to stop after reading the first line. It also doesnt seem to be writing to my output file but does create it when I run the program. This is what my text file looks like

10
150.4
88.4
-3.14
499.4
799.4
1299.8
0
1900.2
901.7
4444.4

This is what my program looks like

import java.util.*;
import java.io.*;
 public class assignment7scratch
{
  Toolkit_General toolKit = new Toolkit_General();
  public static void main (String[]args)throws IOException

[Code] .....

so I dont get an error but this is what my output looks like

----jGRASP exec: java assignment7scratch

This program reads a list of values representing number of miles driven by individuals. It will output the dollar amount their rental cars cost.

Number of miles traveled on the left as well as amount reimbursed on the right

-----------------------------------------------
Miles Driven Amount reimbursed
150.427.072

----jGRASP: operation complete.

it also doesn't write anything to my output file, though it does create one.

//This line should not be read
even this should not be read #$%^&
11-07-1009:20New York25.00ColdPlay

That particular line should be escaped. Till now I have done when the file format is proper, and it is as below:--
 
public static void main(String[] args) {
BufferedReader br = null;
String temp = null;
List<String> arrayRead = new ArrayList<String>();
try{

Read In Java Source Code File As Command Line Argument

Oct 31, 2014

I am trying to complete this question. I understand the most of it but I haven't go a clue to read in the file name.

Full question: Implement a program that reads in a Java source code file and checks to see if it has balanced {}brackets. Your program should use a stack, implemented as a linked list, to check the brackets.

NOTE: you can use a reference called top which points to the head of the list. Your program should run as a command line program and should take a filename as an argument and print one of BALANCED or NOT BALANCED.

For example: c:> java checkBalanced "myProgram.java" BALANCED

Binary Tree - Storing Each Word As String And Int Frequency For Each Time Word Occurs

Apr 27, 2015

I have built a binary tree, from a file. In each node, I am storing each word as a string, and an int frequency for each time the word occurs. For the assignment, I need to find how many words occur only once in the file. I wrote the program, but for some reason I am getting a number different from what my professor is expecting.

As far as I know, this file has loaded into the tree correctly, because all of my other answers in the assignment are correct. What am I doing wrong?

public void findUnique() {
System.out.println("There are " + findUniqueWords(root, 0) + " unique words.");
}
private int findUniqueWords(Node subTree, int uniqueCount) {
// Base Case: At the end of the branch
if(subTree == null){
return uniqueCount;

Adding String Line To Existent TXT File

Feb 7, 2015

i'm trying to add new value (string type) in an existent file.say that we have a .txt file which contain "mario"...i ask to the user a new name, and he write for expample "tony", now i want append the word "tony" in the existent file in this way: Iwrote this code:

Java Code:

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
import java.io.PrintWriter;

[code]....

first is saved next to the value existing. why? maybe because the program does not check if there is a string in the file?but I do not think. because otherwise it would happen with any name that is not entered in an odd position.

How To Check For A String In The File And Get Start And End Line Numbers

Aug 13, 2014

write the logic in the below given Java method.

Trying To Read In A String From Text File

So I am saving a file. it is an array of two strings each containing three words. i figured out how to save to a text file and read it back in and put it back into an array. I am using scanner.hasnext and scanner.next and i think that separates the strings into variables using the spaces in the strings. Well for my project i need to do it with a symbol instead of a space

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.Writer;
import java.util.Scanner;

I put some comments in the read method so you can get exactly what im trying to accomplish....
