How To Make A Text File Only Use Lines In A Text File Beginning With A Certain Letter
Mar 15, 2015I 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?

Oct 31, 2014 Make a password rule, and take input of the password from the user and compare the password with your rule, if the user had entered valid password then print the message, password valid, else the password is invalid for (the whatever) reason.

System.out.print("Please enter a Password: ");

View Replies View RelatedSplit Text File Lines Into Pieces And Put Them In Different Array Lists?
Mar 14, 2015For example, if I had a text file with one line such as "first, second, third", would there be a way to make it so I could make "first" go to the first array list, "second" to the second, and "third" to the third?
I haven't posted any of my code so far as it wouldn't be right to be handed the finished code on a platter and I should put the work into it, but I'd just need a loop to make it go through the rest of the lines in the text file to add all the first, second and third parts of each line, right?
(I already know how to input data from a file, but not how to split up a line into bits to put into different array lists).

Dec 12, 2014I 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()){

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?

Mar 16, 2014I have to write a program that reads the input from a text file!
Beware the Jabberwock, my son,

Beware the JubJub bird and shun
the frumious bandersnatch.
I should print the number of lines, the longest line, the number of tokens on each line and the length of the longest token on each line.
I was able to find the number of tokes in the line but im having having problems reading the longest word ,, my program gives me the number of letter of each line instead of only the number of letter of the longest word!!
this should be my output:
Line 1 has 5 tokens (longest = 11)
Line 2 has 8 tokens (longest = 6)
Line 3 has 6 tokens (longest = 6)
Line 4 has 3 tokens (longest = 13)

View Replies View RelatedPrint Array Output On Different Lines
Nov 19, 2014I've to read in an array of 1000 random numbers, and then my program sorts them depending on whether the user chooses bubblesort, selectionsort, etc...My code all works fine, my problem is with the actually output display. I have method that displays the content of the array that I call for the unsorted array, and for the sorted array. So at the moment the output to the user looks like:This program sorts an array of numbers by your choosing.
Array before sorting:
148
626
817
4
312
652
643
134
etc... for 1000 numbers
----------------------
1. Bubble Sort
2. Selection Sort
3. Insertion Sort
4. Merge Sort
5. Quick Sort
----------------------
Please enter your sort choice: 4
Array after sorting:
1
3
4
4
5
6
6
7
etc... for 1000 numbers
is there a way that I can display the unsorted and sorted array's content on various lines like so:
150 312 149 31 392 384 66
498 909 35 602 568 897 131
654 645 274 264 895 281 462
244 171 958 649 740 351 344
I just think it'll look nicer if I can do it like that.My display method looks like this:
//method to display array
public static int[] displayArray(int[] array){
//display array
for (int i =0; i < array.length; i++)

Reading Text File With Specific Input Format - Output Formatted Report
Apr 10, 2014Here's a link to it : [URL] ....
The basic gist is it's "A program that reads in a text file that uses a specific input format and uses it to produce a formatted report for output."
Specifically :"For this lab you will write a Java program that produces a simple formatted report. The program will prompt the user to enter a file name. This file must contain information in a specific format (detailed below). Each "block" of the file contains information for one player in a competition -- the name of the player followed by a number of different scores that that player achieved. The program should find each player's average score, median score and best and worst scores and display them in a line on the final summary report. The program should also determine which player has the highest average score and which player has the lowest average score."
I get the following errors when I try and compile it:
Enter an input file name: Project11.txt
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException... -1
at java.util.ArrayList.elementData(Unknown Source)
at java.util.ArrayList.get(Unknown Source)
at Project11.getMedian(Project11.java:68)
at Project11.main(Project11.java:27)
I get that the error(s) reside in lines 68 and 27, among problem other areas, but I'm not exactly sure how I can fix them.
Here's my code:
import java.io.*;
import java.util.*;
public class Project11 {
public static void main(String[] args) throws IOException{
Scanner in = new Scanner(System.in);
System.out.print("Enter an input file name: ");

Read Line Of Text And Output Text First In All Uppercase And Then In Lowercase Letters
May 29, 2014Write a program that reads in a line of text and then outputs that line of text first in all uppercase letters and then in all lowercase letters.
INPUT and PROMPTS. The program prompts for a line of text as follows: "Enter the text: " and then reads in an entire line of text as a String .
OUTPUT . There are four lines of output . The first line is "The text in all upper case is: ". The second line is the line that was read in, displayed in all uppercase. The third line is "The text in all lower case is: " and the fourth line is the original line that was read in, displayed in all lowercase.
CLASS NAMES. Your program class should be called ShoutAndWhisper.
This is what I have so far:
import java.util.Scanner;
public class ShoutAndWhisper
{
public static void main(String[] args)
{
Scanner scannerObject = new Scanner (System.in);
System.out.println("Enter the text: ");
scannerObject.next();
System.out.println("The text in all upper case is: ");

Application That Reads In A Line Length Followed By Individual Lines Containing Text
Jan 9, 2015I'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.
