We Keep Coding

Every time a new swing windows opens in code that is executed in a for loop

Every time a new swing windows opens in code that is executed in a for loop.
I have some code that is runned in a for loop.
The for loop gives every time a new value to my multidimensional array.
But, every time my for loop creates open's a new windows but does not close the old window.
How can I solve this issues? I want to close the old windows and refresh my window with the new actual values or that only one Windows is opened and that the new values of the for loop refreshes the values inside the table based on the multidimensional array names data.
Because now more than 200 (every second a new windows is opened) windows are opened and after 1 minute I don’t see new values appearing on my window and the computer freezes.

The UappWin seems to be tied to a window. So when you create it, also create a JFrame. Then nothing else would need to change except the run method and declaring the JFrame.
public class UAppWin {
private JFrame frame;
public UAppWin(String label, int nphases) {
//System.out.println("UApp \"" + label + "\" (" + nphases + " phases)");
JLabel label = new JLabel("UApp \"" + label + "\" (" + nphases + " phases)");
frame = new JFrame("title");
frame.add(label);
frame.setVisible(true);
}
Then when you create the window.
SwingUtilities.invokeLater(new Runnable() {
public void run() {
//JOptionPane.showMessageDialog(null, new JScrollPane(getNewRenderedTable(getTable())));
frame.setContentPane( new JScrollPane( getNewRenderedTable( getTable() ) );
frame.setVisible(true);
}
});

repaint() method not calling paintCompnent

I am trying to make a JFrame program that interfaces a binary-decimal-hexadecimal converter with buttons. A part of this, I would like to draw circles to represent binary numbers in a row of circles with a filled circle representing a one and an empty circle representing a zero. However, when I try to call repaint to draw anything, it does not execute the paintComponent() method, which I know because it does not perform the print statement inside of it. Full code below:
package e2;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.awt.FlowLayout;
public class DecBin extends JPanel {
String theText = "IT WORKS";
int style = Font.BOLD; // bold only

f.setSize(1000, 1000);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setLayout(new FlowLayout());
Font font = new Font("Arial", style, 40);

textLabel.setFont(font);
JButton b = new JButton("DectoBin");
b.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
String msg = JOptionPane.showInputDialog("input a decimal number");
int num = Integer.parseInt(msg);
theText = num + " is " + decToBin(num) + " in binary";
textLabel.setText(theText);
}
});
f.add(b);
JButton d = new JButton("BintoDec");
d.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
String msg = JOptionPane.showInputDialog("input a binary number");
System.out.print("The decimal form of " + msg + " is " + binToDec(msg));

public void paintComponent(Graphics g) {

} else {
total += Character.getNumericValue(b.charAt(i)) * Math.pow(16, len - i - 1);
}
}
return total;
}
}
Pertinent code in my opinion is:
DecBin() {
JFrame f=new JFrame("Decimal to binary and binary to decimal converter");
f.setSize(1000,1000);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setLayout(new FlowLayout());
JButton c =new JButton("Draw");
c.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.out.print("test1");
validate();
repaint();
}
});
f.add(c);
f.setVisible(true);
}
public void paintComponent(Graphics g) {
Graphics2D g2 = (Graphics2D) g;
g2.setColor(Color.red);
g2.fillOval(100, 100, 20, 20);
System.out.print("painted components");
}
public static void main(String[] args) {
new DecBin();
}
I have spent hours researching this and have yet to find a solution that will get "painted components" to print.

You do not appear to be adding your DecBin panel to any other UI element. It therefore has no reason to be painted.
You should avoid initializing JFrames inside the constructor of your JPanel child class - it should really be the other way around. That will make things easier to understand (and to debug).

code inside jButtonActionPerformed(ActionEvent e) method is not working

I have a jTextField, jLabel and a jButton. I want to set the jTextField to empty and update the jLabel to some new text after I perform jButton action.
This my code for jButtonActionPerformed(ActionEvent e) method:
private void jButton8ActionPerformed(java.awt.event.ActionEvent evt) {
BufferedWriter fw;
StringBuilder guessword = new StringBuilder(word);
try {
fw = new BufferedWriter(new FileWriter("C:\\Users\\Arihant\\JavaApplication1\\src\\javaapplication1\\scores.txt", true));
while(guesses != 0) {
jLabel26.setText(Integer.toString(guesses));
guesschar = jTextField2.getText().charAt(0);
flag = 0;
for(int j = 0; j < word.length() / 2; j++) {
if(Character.toLowerCase(guesschar) == temp[j] && (guessword.toString().indexOf(Character.toLowerCase(guesschar)) < 0)) {
flag = 1;
for(int k = 0; k < word.length(); k++) {
if(Character.toLowerCase(guesschar) == word.charAt(k))
guessword.setCharAt(k, Character.toLowerCase(guesschar));
}
if(guessword.toString().equals(word)) {
switch (difficulty) {
case "EASY":
points = guesses * 50;
break;
case "MODERATE":
points = guesses * 100;
break;
case "HARD":
points = guesses * 200;
break;
default:
points = 0;
break;
}
try {
fw.append(name + " " + points);
fw.newLine();
fw.close();
} catch (IOException ex) {
Logger.getLogger(HangMan.class.getName()).log(Level.SEVERE, null, ex);
System.out.println(ex);
}
jPanel13.removeAll();
jPanel13.add(jPanel4);
jPanel13.repaint();
jPanel13.revalidate();
jLabel29.setText("<html>YOU WIN!<br/> The word was: </html>" + word);
jLabel31.setText("You scored: " + points + " points.");
jLabel28.setText("Play again?");
}
}
}
if(flag == 0) {
guesses--;
}
jPanel13.repaint();
jPanel13.revalidate();
jLabel1.setText(guessword.toString());
jTextField2.setText("");
Document document = jTextField2.getDocument();
document.addDocumentListener(new JButtonStateController(jButton8, 0));
((AbstractDocument) jTextField2.getDocument()).setDocumentFilter(new JTextFieldFilter(0));
}
} catch (IOException ex) {
Logger.getLogger(HangMan.class.getName()).log(Level.SEVERE, null, ex);
System.out.println(ex);
}
}
When I click jButton8, it just skips the entire code in try-catch block and goes directly to jPanel13.removeAll();.
I want to set the jTextField2 to empty and jButton8 to disabled, each time I click jButton8.
Tell me, where I am wrong and how can I improve my code?

If what you want is to display the full text of the cells instead of an abbreviation, you can use the Table Column Adjuster. e.g.:
String[] columnNames = {"Colum1", "Colum2", "Colum2"};
String[][] data = {
{"ABCDEFGHIJKLMNOPQRSTUVWXYZ", "-", "-"},
{"-", "ABCDEFGHIJKLMNOPQRSTUVWXYZ", "-"},
{"-", "-", "ABCDEFGHIJKLMNOPQRSTUVWXYZ"}
};
TableModel model = new DefaultTableModel(data, columnNames);
JTable table = new JTable();
table.setModel(model);
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
TableColumnAdjuster tca = new TableColumnAdjuster(table);
tca.adjustColumns();
JScrollPane pane = new JScrollPane(table);
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(pane);
frame.setSize(400, 300);
frame.setVisible(true);
You can get the code for the class TableColumnAdjuster from http://www.camick.com/java/source/TableColumnAdjuster.java
