I am setting text to textarea from textfield. It works perfectly. My challenge, however, is setting texts with spaces in-Between them. For example, what I observe is:Amount23 instead of: Amount 23. Is it possible to automatically create word space while setting texts?

I am making use of NetBeans IDE 8.0 to build a GUI. The idea is that I set multiple values received from textfields to textarea. This will enable me print the work. But ONLY ONE value from textfields is set(appear on textarea); the others do not appear at all. Below is example of what I mean:
String s = jTextField1.getText();
JTextArea1.setText(s);
String x =
jTextField2.getText();
JTextArea1.setText(x);
Only one is being set. The rest are not.
I am attempting to create a 2d game that has a realistic space simulation. The map is supposed to be set so that you are looking from the top down. The problem I am having exists in my interaction between the sun and a planet. Simply put, the planet will only move in a single diagonal direction without ever changing direction. The formulas I am using are F=(G*M1*M2)/D^2 and A=F/M. The code below is simplified.
(inside planet Class)
double x;
double y;
double mass;

In my java web jsf seam jboss application, I want to add a row in a table with some data fields such as date type, String etc, but one field will be a word attachment, how to do it?
Basically, there is a loop to create some rows of data in a table, before each table row data creation, I will create a word file and saved to a local path(the physical file path is hardcoded), then I will create a table row and attach this word file to that row. the loop will continue until the end of loop.
For class, we need to create a word game using classes and objects.
The game is played in rounds. The player is presented with a word that is missing letters. The player has to fill in the missing spaces with their letter guesses. The words presented are chosen with a random number generator which has been provided for us. At the end of the game, the player is shown their score.
In steps, I have to:
-Welcome the player.
-Present the puzzle.
-Allow the player to fill in the blanks.
-Have the program check responses for correct/incorrect input.
-End the game if they have three misses, or continue if they complete the puzzle.
Now, to start, I have a class for the number generator, a class to store the array of 25 words, and a class for the game itself.
there is a main JPanel in my application in that main JPanel i want to add two JPanels with a seperator in between . Though i have added the seperator but its taking some extra space and when i am changing its size , there is no effect . how can i remove/reduce this extra space taken by JSeperator? below is view logic ,
mainPanel = new JPanel(new GridLayout());
jp = new JPanel(new GridLayout(8, 2, 5, 5));
jp2 = new JPanel(new GridLayout(8, 1, 5, 5));
jText = new JTextField(10);

The question is Write a program that displays all the numbers from 100 to 1000, ten per line, that are divisible by 5 and 6. and separated by exactly a space.
My assignment requirements are to display this in Dialog Box / message box . I have written this code so far
import javax.swing.JOptionPane;
public class Exercise04_10 {
public static void main(String[] args) {
int count = 1;
for (int i = 100; i <= 1000; i++)
if (i % 5 == 0 && i % 6 == 0)
How to display the output in dialog box?
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;
[Code] ....
The intentions of this program is to prompt a user to enter a file name, and then reads the file. The program will prompt the user to enter a word that needs to be corrected. So lets say I have a text file containing "My name is OP and I Like goind to the Park!" I want to change "goind" to "going",
Now, my second method "isSimilar" executes a similar word with more than one same letter and same length, but I dont know how to execute that whole thing in my third method "correctThisLine" . How I can call that isSimilar method and read in that text file and change that word into that?

I am looking for java codes to generate a word document based on a word template, basically, I have a word template created and in my local path, the template has a proper format with some fields which will be filled in after java codes ran. The java codes will fetch one record from a table, and open the word template and then fill the fields in the word template, and created a new word document and save it in another folder.
I found this example: [URL] which is similar except it uses xml template instead of word template, how to make it work to change the template from xml to word (docx) template?

I want to write a text area to a file which I have accomplished however the formatting for how it is written into the text file is different. Is there a different library I must use to retain the formatting?
I'm using a BufferedWriter to write to the file
if (!file.exists()) {
try {
BufferedWriter output = new BufferedWriter(
new FileWriter(file));
output.write(textArea.getText());
output.close();
} catch (IOExcception io) {
io.printStackTrace();
}
}
If I write this into the text area:
DreamInCode
YouTube
Google
The text file contains text that says:
DreamInCodeYouTubeGoogle
i can use this current code to change it so that it use TextArea in jsp and the keylistener code in servlet. i know i have to take out the JFrame,JTextfield and ContentPane but still i could not do it.

I am having trouble with getting a user input once they enter it in to a JTextArea and then storing it in to a string value. See, I wanted the user to enter an answer in to the JTextArea, and then once I store it in to a string value, I would be able to use it later. I wanted to after storing the variable to print it on to a JLabel, but nothing is showing up... Heres my code.
static String usera[]= new String [10];
for (int i=0; i< usera.length; i++) {
//These are the JTextArea names
usera[0]= Question1.getText();
usera[1]= Question2.getText();

I already initialized the JLabels earlier in my code, and I did not feel the need to post all my code here. This is where I am trying to get the string variable and then printing it out.
i am doing a program that allow user to run and execute java language in this commandline.jsp, a servlet execute.java , jsp called get consoleout put.jsp to direct it to commandline.jsp...however there a compilation errors cos i could only get a line of string, and when i run loop in commandline.jsp it will not have the output. i could only run helloworld in it.therefore i need code that i can run multiple line in it. i suspect its the print stream error in execute.java

View Replies View RelatedI have a TextArea that I am trying to restrict user inputs to allow only IP addresses format in that Area. So I thought of only allowing digits and decimal points. For multiple IPs, One IP per line, the TextArea needs to accept new lines. For the most part what I have below is working except for delete. I can't delete any entry even if I am using the associate Unicode. Is this even the correct way of doing it?

I have a TextArea and want to set a linear-gradient as background, which works fine:
.text-area {
-fx-background-color: linear-gradient(to bottom, red 0%, blue 100%);
}
The problem is that if the TextArea contains much text (and long scrollbars) it is nearly only red. Only if you scroll down to the bottom, it becomes blue.
I want the red-blue gradient always look the same, no matter how much text there is.
In HTML there's something like background-attachment: fixed, which would do the trick, but not so in JavaFX.
Can I achieve it nonetheless. Preferably without any ugly workarounds, like a transparent TextArea within another Pane where the wrapping Pane has the gradient.
We have a requirement that we need to have text area/text box on screen to accept multiple languages like (Spanish and russian) that means user can able to enter their text data either in any language like english,russian and spanish(It should be possible to enter the comments in russian and spanish languages). Is it possible to implement in java/j2ee?
View Replies View RelatedI'm just messing around with JFrames and stuff like that (like previous posts). There is no ultimate goal here, which I realize violates that I should write everything down beforehand and know what I'm trying to accomplish. My question is, does this look ok? I'm going to start doing if...else statements but don't want to move on if I think this is bad programming. Any tips on how I create new JFrames under and if...else statement?
