How to change the JTextField values inside a loop

I need some help with my program. I'm trying to make a brute force program as a project and I don't know how to make the loop values appear in the JTextField in the print () method. I don't just need the final value of the loop. I know this question has been asked a lot and I've tried everything but it's just not working. Please can anyone help me? I'll appreciate it !

}
}

For example, the string 123 has length 3 so the permutations can be 000,001,002 etc
Then why only display one at t time?
Instead I would use a JTextArea and append each value to the text field so all values are visible at the same time. Nobody is going to remember all the values if you display one at a time.
Otherwise, you would use a Swing Timer to display one at a time.

JInternalFrame does not show up

from my MainFrame I create a internal Frame and add that to my desktop pane, but the internal Frame just won't show up. I tried to figure it out for 3 hours now and I kinda need some help with it. Before I implemented the observer pattern it just worked fine. So I thought it got something to do with that and changed some stuff and double checked the crucial code. No solution so far. I just realized how crappy my english is sometimes. Sorry for that!
The 2 code blocks are already shortened. Sorry that they are still pretty long. But I am just not sure where I made the mistake. If you need more code or anything else, just tell me. Thank you very much in advance.
This is the code of my main frame:

I think it is because you didn't set size for your JInternalFrame. In your code it is as a comment:
//kind.setSize(370, 370);
when I remove "//" it works for me.

Application not displaying GUI and won't quit Java

So I'm creating a game in Java and I ran into a little problem. Whenever I run the application the GUI does not show on the screen and the only way to close the application is to use the Windows Task Manager. In the application, you choose a username and click an enter button which creates a new window in which the game is played. But after you click the button, none of the GUI loads and you can't close the application.
Basically, when you click the button, a method is called that disposes the current window and starts the game window. The code for that method is below:
public void login(String name) {
String[] args={};
dispose();
SingleplayerGUI.main(args);
}
And here is the code of the SingleplayerGUI class:
public SingleplayerGUI(String userName, Singleplayer sp) {
this.userName = userName;
setResizable(false);
setTitle("Console Clash Singleplayer");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(880, 550);
setLocationRelativeTo(null);
System.setIn(inPipe);

if (menu.equals("start")) {
start();
} else if (menu.equals("quit")) {
quit();
} else {
menuScreen();
}
}
private static void quit() {
SingleplayerGUI.console("You quit the game.");
}
private static void start() {
SingleplayerGUI.console("You started the game.");
}
So far I've figured out that the problem most likey occurs when adding the outPipe to the console. Would I be able to fix this or am I just not able to use outPipes with this application?
Thanks in advance for your help.

The setVisible() method is invoked twice.. Remove the second setVisible() call after the Singleplayer.startOfGame(); line in SingleplayerGUI constructor.

Change Title of JFrame in my program

I am having trouble with one part of my code. I have been working for so long on this and I am exhausted and missing something easy. I need to have a text box to enter a new title for the JFrame, a button that says "Set New Name" and an "Exit Button.
Can someone look at this code and give me some info so I can go to bed.
Thank you

Let's start with this (which I assume is where you create the details)...
private void optionsTab() {
optionsPanel = new JPanel(new FlowLayout());
//optionsPanel.setLayout(null);
JLabel labelOptions = new JLabel("Change Company Name:");
labelOptions.setBounds(120, 10, 150, 20);
optionsPanel.add(labelOptions);
final JTextField newTitle = new JTextField("Some Title");
newTitle.setBounds(80, 40, 225, 20);
optionsPanel.add(newTitle);
final JTextField myTitle = new JTextField("My Title...");
myTitle.setBounds(80, 40, 225, 20);
myTitle.add(labelOptions);
JButton newName = new JButton("Set New Name");
newName.setBounds(60, 80, 150, 20);
//newName.addActionListener(this);
optionsPanel.add(newName);
optionsPanel.add(createExitButton());
}
The newTitle field is a local variable, so once the method exists, you will not be able to access the field (easily)...
You seem to have tried adding a actionListener to the newName button, which isn't a bad idea, but because you can't actually access the newTitle field, isn't going to help...
The use of setBounds is not only ill advised, but probably won't result in the results you are expecting, because the optionsPane is under the control a layout manager...
And while I was digging around, I noticed this if (errors != "") {...This is not how String comparison is done in Java. This is comparing the memory references of both Strings which will never be true, instead you should if (!"".equals(errors)) {...
But back to the problem at hand...
You are really close to having a solution. You could make the newTitle field a class instance variable, which would allow you to access the field within other parts of your program, but because you've made it final, there's something else you can try...
You can use an anonymous inner class instead...
newName.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
setTitle(newTitle.getText());
}
});
Which should get a good nights sleep :D

It is a little unclear what you want, but if I understand you right you want the JButton newName to set the title of the JFrame to the text in some textbox?
In that case you would write
setTitle(someTextbox.getText());
inside the function of the button.

First, you need to create a JTextField that has public access. Then, create a JButton that implements ActionListener. After that you must implement the abstract method actionPerformed() in the JButton Subclass. Then in the run method say JFrame.setTitle(JTextfield.getText()).
Subclass Method:
public class main extends JFrame{
// Construct and setVisible()
}
class textfield extends JTextField{
// create field then add to JFrame
}
class button extends JButton implements ActionListener{
// create button
public void actionPerformed(ActionEvent e){
main.setTitle(textfield.getText());
}
Instance Method:
public class main implements ActionListener{
JFrame frame = new JFrame();
JPanel panel = new JPanel();
JTextField field = new JTextField();
JButton button = new JButtone();
button.addActionListener(this);
panel.add(field);
panel.add(button);
frame.add(panel);
public void actionPerformed(ActionEvent e){
frame.setTitle(field.getText);
}
}

Try This
private void optionsTab() {
optionsPanel = new JPanel(new FlowLayout());
// optionsPanel.setLayout(null);
JLabel labelOptions = new JLabel("Change Company Name:");
labelOptions.setBounds(120, 10, 150, 20);
optionsPanel.add(labelOptions);
final JTextField newTitle = new JTextField("Some Title");
newTitle.setBounds(80, 40, 225, 20);
optionsPanel.add(newTitle);
final JTextField myTitle = new JTextField("My Title...");
myTitle.setBounds(80, 40, 225, 20);
myTitle.add(labelOptions);
JButton newName = new JButton("Set New Name");
newName.setBounds(60, 80, 150, 20);
newName.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
setTitle(newTitle.getText());
}
});
// newName.addActionListener(this);
optionsPanel.add(newName);
optionsPanel.add(createExitButton());
}

Update JLabel every X seconds from ArrayList<List> - Java

I have a simple Java program that reads in a text file, splits it by " " (spaces), displays the first word, waits 2 seconds, displays the next... etc... I would like to do this in Spring or some other GUI.
Any suggestions on how I can easily update the words with spring? Iterate through my list and somehow use setText();
I am not having any luck. I am using this method to print my words out in the consol and added the JFrame to it... Works great in the consol, but puts out endless jframe. I found most of it online.
private void printWords() {
for (int i = 0; i < words.size(); i++) {
//How many words?
//System.out.print(words.size());
//print each word on a new line...
Word w = words.get(i);
System.out.println(w.name);
//pause between each word.
try{
Thread.sleep(500);
}
catch(InterruptedException e){
e.printStackTrace();
}
JFrame frame = new JFrame("Run Text File");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JLabel textLabel = new JLabel(w.name,SwingConstants.CENTER);
textLabel.setPreferredSize(new Dimension(300, 100));
frame.getContentPane().add(textLabel, BorderLayout.CENTER);
//Display the window. frame.setLocationRelativeTo(null);
frame.pack();
frame.setVisible(true);
}
}
I have a window that get's created with JFrame and JLable, however, I would like to have the static text be dynamic instead of loading a new spring window. I would like it to flash a word, disappear, flash a word disappear.
Any suggestions on how to update the JLabel? Something with repaint()? I am drawing a blank.
Thanks!
UPDATE:
With the help from the kind folks below, I have gotten it to print correctly to the console. Here is my Print Method:
private void printWords() {
final Timer timer = new Timer(500, null);
ActionListener listener = new ActionListener() {
private Iterator<Word> w = words.iterator();
#Override
public void actionPerformed(ActionEvent e) {
if (w.hasNext()) {
_textField.setText(w.next().getName());
//Prints to Console just Fine...
//System.out.println(w.next().getName());
}
else {
timer.stop();
}
}
};
timer.addActionListener(listener);
timer.start();
}
However, it isn't updating the lable? My contructor looks like:
public TimeThis() {
_textField = new JTextField(5);
_textField.setEditable(false);
_textField.setFont(new Font("sansserif", Font.PLAIN, 30));
JPanel content = new JPanel();
content.setLayout(new FlowLayout());
content.add(_textField);
this.setContentPane(content);
this.setTitle("Swing Timer");
this.pack();
this.setLocationRelativeTo(null);
this.setResizable(false);
//_textField.setText("loading...");
}
Getting there... I'll post the fix once I, or whomever assists me, get's it working. Thanks again!

First, build and display your GUI. Once the GUI is displayed, use a javax.swing.Timer to update the GUI every 500 millis:
final Timer timer = new Timer(500, null);
ActionListener listener = new ActionListsner() {
private Iterator<Word> it = words.iterator();
#Override
public void actionPerformed(ActionEvent e) {
if (it.hasNext()) {
label.setText(it.next().getName());
}
else {
timer.stop();
}
}
};
timer.addActionListener(listener);
timer.start();

I got it working with this code... Hope it can help someone else expand on their Java knowledge. Also, if anyone has any recommendations on cleaning this up. Please do so!

You're on the right track, but you're creating the frame's inside the loop, not outside. Here's what it should be like:
private void printWords() {
JFrame frame = new JFrame("Run Text File");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JLabel textLabel = new JLabel("", SwingConstants.CENTER);
textLabel.setPreferredSize(new Dimension(300, 100));
frame.getContentPane().add(textLabel, BorderLayout.CENTER);
//Display the window. frame.setLocationRelativeTo(null);
frame.pack();
frame.setVisible(true);
for (int i = 0; i < words.size(); i++) {
//How many words?
//System.out.print(words.size());
//print each word on a new line...
Word w = words.get(i);
System.out.println(w.name);
//pause between each word.
try{
Thread.sleep(500);
}
catch(InterruptedException e){
e.printStackTrace();
}
textLabel.setTest(w.name);
}
}
