I am working on a personal project and want to create a text editor to write my code. I am wondering how could I read the last input from the user and if say it was an open curly brace {, then like netbean's my editor will supply the closing curly brace. My java experience is limited but I have tried to read key board input and a few other options that did not work.

I am building a chat server/client and would like to have it so when a user sends a message, the message pops up in the main chat area beside their name, which I would like to be in bold font. Something like "Alan: Hello, how are you?". I can't find a way to do this with a text area or on a string. Do any swing components suitable for use as text areas support bolding of certain sections of the string that you will set to it?
View Replies View RelatedIm writing a program that records the score in a dart game. One component of the program is a stage where players enter their name.This information needs to be displayed in another part of the program. These two components are in two different classes. My problem is I dont know how to get that information from one class to another.
Im using Jtextfield in Jframe to record the information.
I am stuck on one of the projects: Area Calculator
I am able to code an area calc that works, but am unsure how to move all the input/output to main like the project wants. here is a piece of my code so far:
public static void main( String[] args )
{
Scanner kb = new Scanner(System.in);
int base = 0, height = 0, width = 0, radius = 0, choice;
System.out.println( "-=-=-=-=-=-=-=-=-=-=-" );
System.out.println( "1. Triangle" );
System.out.println( "2. Rectangle" );
System.out.println( "3. Square" );
System.out.println( "4. Circle" );
System.out.print( "Pick a shape: " );
[Code] ....
I have the same thing for rectangle, square, and circle (of course with the correct formulas) and the program works perfect, but the assignment is still wrong until I can move the input/output to main. what do I do?
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?
I have a popup that displays textual info and sometimes gets text input from the user. I'm using the following code:
JTextArea textArea = new JTextArea( getGameHistory( true, -2 ) );
JScrollPane scrollPane = new JScrollPane(textArea);
textArea.setLineWrap(true);
textArea.setWrapStyleWord(true);
textArea.setFont(new Font("courier", Font.PLAIN, 12));
scrollPane.setPreferredSize( new Dimension( 30, 100 ) );
String input = JOptionPane.showInputDialog(null, scrollPane, "Fun Chess ",
JOptionPane.YES_NO_OPTION);
This shows a nice text area and an input field underneath it.The getGameHistory() method just returns a long string detailing the current game.Is there a way of just showing the text area without the input field underneath?Can the text area also be used for input instead?
trying to tranfer content of a text area on one jframe to a text area in another
View Replies View RelatedI have a requirement where in the content of the text area is dynamically populated from the database. I am able to successfully retrieve and display the data on the text area.
However when the content is too large, I am not able to dynamically set the height of the text area. When I try to display the same as a label, the display is flawless, dynamically sets the height as per the content. So, I tried to create a label, with same content and dynamically bind the height to the preferred height as below, but it doesn't work.
// Generate User Note Description
TextArea textArea = new TextArea();
Label text = new Label();
// SETTING THE TEXT TO A LABEL TO RETRIEVE THE HEIGHT
text.setText(usrNotes.getNote().trim());
[Code] ....
The problem is i want to replace some string text with foreign characters, but JTextArea returns plainText.
For Example:
str = new String();
str.replace('e', 'é');
textArea.setText(str);
but textArea returns plainText.
Write 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: ");

How can I read a text file present in my local directory say (C://test.txt) , iterate and populate the values of test.txt into a text area of the JSP page?

BaseFrame

In my application, some text should be added to a text area in response to a click on a button. So as an action listener to this class, I made another class which implements the ActionListener.
Inside this class, I have obtained the text which I want to be added to the text area. But the text area is in another class and for the action listener I wrote another class.
Now the problem is that when I try to add the text to the text area by the following line of code, it says that textArea_1 can not be resolved or is not a field.
Java Code:
ParentPanel.textArea_1.setText("Name:"+ncrarray[0]+"
Code:"+ncrarray[1]+"
Rank:"+ncrarray[2]); mh_sh_highlight_all('java'); What should I do about it?
Even if I try to write a method like the following in the class in which the text area is created, it gives the same error.
Java Code:
public void printTextArea(String text) {
textArea_1.setText(text);
} mh_sh_highlight_all('java');
The text area is present inside a constructor of the class. I am writing the method outside the constructor (ofcourse).
I have to write a gui program where I can enter a file name and then it gets displayed in a text area when I click Open. Conceptually, I do not get this. I was thinking of appending the text file into a string or something, but I guess I'm confused on how it all works and how I can open the text file. Not asking for the code, but just a compass or something.

**Here is my question. I'm trying to use input and loop method to search for a file. The above code works but my problem is lets say I try to find 2 different text files**
1. billing-20140527[09].txt has
a)XGMS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
b)XGMS,2034-05-27 30:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
2. billing-20140527[10].txt has
a)XCGS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
b)HELO
I try to find the number 1 in both text files, if lets say I input the text file name is billing, I can find the number 1 in both text file and output them:
a) XGMS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
B)/> XCGS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
However, if I specify the text file name: billing-20140527[09].txt and find the number 1 inside the text file, it will only output:
a) XGMS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
How can I do so? Because I can output the number 1 from both text files even though I specify the name.

the jaws that bite, the claws that catch,
Beware the JubJub bird and shun

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)
Longest line : the jaws that bite, the claws that catch,

I need the console to display BOLD for the movie title only. I imported java.awt but I do not know what else or how else to do it. I have looked in my book, online, youtube, yahoo answers and I want to figure this out. I found an answer on here that someone talked about java.awt but did not specific what.
I'm trying to copy my program output to a text file and still have it be displayed in the console.

I am a beginner . How to add output for both valid and invalid lines in text file scanned in java ...
View Replies View RelatedHere'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
