I have a problem with my code,in fact I can't output the stream from console to my jTextarea,this is my code:
public class AudioFrame extends javax.swing.JFrame {
static double[] audioFile;
static String audioToDecode;
static String audioKey;
static String outputName;
static String outAudio;
static String name;
static int command;
static String textToEncode;
[Code]...
I have small problem in GUI. I have a text area which has to display my test orders now what is happening instead of the text showing up in the JtextArea its still printing to the console so this order code (yes i did not use proper code standers) runs though my order class fine but its not loading the text in the JtextArea
Order code
public static String testCase1(){
orders ords = new orders();
System.out.println("Test Case 1: " + "
" + ords.getOrderDetails());
return " ";
My jbutton code :
txtContent.setText(new orderTester().testCase1());
txtContent.setText(new orderTester().testCase2());
txtContent.setText(new orderTester().testCase3());
I have 10 test case to load in the jTextArea
So I have been working on this code for a bit now... basically just supposed to be a display for a calculator, next week in my class we are learning about how to make it do stuff. so it's supposed to just look right for now. Should look something like this actually
My first question is this, how can I get the JTextArea to display over the top like the example?
My second question is I just started getting an error that compiled before, and I haven't changed anything about this line. Here is everything.
import java.awt.*;
import java.awt.font.*;
import javax.swing.*;
@SuppressWarnings("serial")
public class CalcDisplay extends JFrame{
String[] buttonText = {
[Code]...
the output looked something like this though note this is an old screengrab from while I was working on it. I have since gotten it to color correctly and I have a jtextarea below the numbers. though I need to get it to implement above the numbers and can't figure out how to do so the other example is what it should look like, disregard the color choice.The error I was getting appeared on line 36
Exception in thread "main" java.lang.Error: Unresolved compilation problems: The method setLayout(LayoutManager) in the type Container is not applicable for the arguments (GridLayout) The constructor GridLayout(int, int, int, int) is undefined
at CalcDisplay.addComponentsToPane(CalcDisplay.java:36)
at CalcDisplay.main(CalcDisplay.java:82)
This code has worked through the whole project and I haven't changed a thing.
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.

I have dragged and dropped a jTextArea from netbeans palette onto my form. But when I right clicked for Event > action > actionPerformed for implementation, I realized such was not there, unlike the jTextField component. For example, I have tried this but it didn't work:

JTextArea txa = new JTextArea();
txa.getText(jTextArea1);
txa.setText(jTextArea1);
txa.setTextWrap(true);

I need to create a simply application that would display the results of two dice thrown five times and the total of those results. This is shown below in the attached file.
The problem is, I have a do-while loop that loops 6 times. Inside the loop, I have 2 random.nextInt(5) that generate random numbers. But how can I output the total? How can I make a variable equal to the sum of the two random numbers if the two random numbers are located inside a do-while loop?
Attached below is also the code I have thus far.

Write a program that will read two numbers and an integer code from the keyboard. The value of the integer code should 1, 2, 3, 4. If the value of the code is 1, compute the sum of the two numbers. If the code is 2, compute the difference (first number minus second). If the code is 3, compute the product of the two numbers. If the code is 4, and the second number is zero, compute the quotient (first divided by second). If the code is not equal to 1,2,3,4, display an error message. The program is then to display two numbers, the integer code and the computed result to the screen

I want to get current RAM usage of my computer and display it in Console View of Eclipse? How can I achieve this?
View Replies View RelatedCreate a class that allows the user to select a file and output the contents of the file to the console. Recommend using a text file to display, java files are text files. You may want to put this code in a method to allow you to complete the remainder of this assignment without overwriting your code.
- You should ask the user to enter the full path to your file to make certain you are processing the correct file.
- Modify your code/add a method to display the contents of the file in reverse order. You do not need to reverse the characters on each line but simply output the lines of the file in reverse order.
Hint: read the content of the file into an ArrayList and then traverse the ArrayList.
this is what i go so far.

I am adding a JTextArea to my JPanel with this code:
commentTextArea.setLineWrap(true);
commentTextArea.setWrapStyleWord(true);
commentTextArea.setVisible(true);
this.add(commentTextArea);
commentTextArea.setBounds(0, 0, 100, 100);
//commentTextArea.setLocation(0, 0);
Whenever I use setLocation(0,0), the JTextArea never moves. It is always in the top middle of the screen, not at (0,0). The same goes for setBounds(0,0,100,100) BUT the height and width are set this way, just not the location. Why is this?

I am currently working on a project that can save text from a JTextArea and also open that same saved text. The problem I am having is that when I open the saved text file it is no longer formatted.
How the file looks before saving/closing:
public class HelloWorld{
System.out.println("Hello World!");
}
How the file looks after being saved/closed then opened:
public class HelloWorld{ System.out.println("Hello World!");}
When I save the file I'm actually saving the entire thing to a single string. When I do this the String eliminates all tabbed spacing and pushes all characters to one single line.
The only ideas I had for fixing this were to either somehow use Format in the String class or record every time user tabs and add to the String.
I have a program with a main panel JPanel that implements KeyListener. I added a JTextArea to which I added as the KeyListener: this, meaning the main panel. I made the JTextArea fill the entire main panel because I want to catch a key press anywhere in the main panel.I catch the key presses and the program does what I want it to.
I added a JToolBar to the program; it is working just fine.Now that I have two components on the main panel - toolbar and panel with textarea -, the textarea must have the focus before it will send the KeyEvent and call keyPressed(). I don't want to expect the user to click on the main window to get the program to start or after each time they use the toolbar.
I have tried calling both requestFocus() and requestFocusInWindow() on the textarea; neither call worked. I put the toolbar at PAGE_END instead of PAGE_START; this worked to allow the program to start but I don't want to have the toolbar at the bottom and once I clicked on a toolbar button, the textarea lost the focus.
I need to be able to give the textarea the focus when the program starts and after the user uses a toolbar button. (I suspect that if I solve the problem when the program starts, I can use the same method after handling a button press.)
Here's a snippet of code from a program I'm making:
private void init() {
...
testInfo = new JTextArea("Progress log:
");
testInfo.setEditable(false);
testInfo.setLineWrap(true);
testInfo.setPreferredSize(new Dimension(testInfo.getPreferredSize().width, 200));
scrollPane = new JScrollPane(testInfo);
scrollPane.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);
scrollPane.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
...
add(scrollPane);
}
The problem is, the JTextArea that's created has a "limited" number of rows - it seems you can still enter more lines than the "limit", but they don't show. I thought it was a problem with the JScrollPane but I'm not so sure...
So, I have a program that allows me to dynamically add JTextAreas and then drag them around the screen. The problem is, when I add a new JTextArea, I call revlidate() to update the panel. This causes all of the JTextAreas to reset their positions. How can I prevent this from happening? It is happening on this code:
public void addBox() {
drag = new DragListener();
JTextArea textArea2 = new JTextArea("Some text
Some other text");
textArea2.setLineWrap(true);
textArea2.setWrapStyleWord(true);

I have a swing application that gets football scores from a website using Jsoup.
When the "Get Scores" button is pressed, the scores are printed to a JTextArea with a JScrollPane.
I have also used a SwingWorker to update the scores every couple of seconds.
My problem is that every time the JTextArea updates, the JScrollPane scrolls back to the top of the text area. I wan the scroll bar to stay where the user left it.

How do I move focus from a jcombobox to a specific component say a jtextarea.
My attempt below seems to be moving to a random component not the desired jtextarea.
takenByCombo.addKeyListener(new KeyAdapter() {
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_TAB ) {
e.consume();
dayJTArea.requestFocus(); // focust not moving dayJTArea
}
}
});
I applied the above logic to move focus from a specific jtextarea to another jtextarea as seen below and it works as desired.
dayJTArea.addKeyListener(new KeyAdapter() {
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_TAB ) {
e.consume();
monthJTArea.requestFocus();
}
}
});
