How can I Resize a JScrollPane with JTable on it?

I created a JTable with some nice functions. My problem is, that it does not resize when I size the frame where it is on. Can someone help me with my Code so it does resize like it should? I alaready tryed some ideas of posts I found but it did not rly help me. So I have tryed to add the JPanel on another one with some Layout ideas. I have also tryed to use ComponentListeners and setSize on resizeaction.
Code:
public class TableyTable extends JPanel {
/**

As in the tutorial described, you need to set a LayoutManager and add the JScrollPane accordingly:
setLayout(new BorderLayout());
add(scrollPane,BorderLayout.CENTER);

Sorting JPanels based on component

My program generates random numbers from 0 to 12 but if the result is 12 it would set dash as the text of JLabel, instead of the number generated.
Now, I wanted to sort my JPanel in ascending order based on the JLabel contents. In case of similarities in numbers, the black JPanels are placed on the left. It works fine except when there are dashes included, in which it doesn't sort properly. I would like to insert the JPanels containing dashes anywhere but it's not working as expected.
Screencaps from a shorter version of my program:
Pure numbers:
Dash included:
Here's the shorter version of my code (using the logic of integer sorting):
import java.awt.*;
import javax.swing.*;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Random;
import java.util.Comparator;
public class SortFrames extends JFrame
{
static ArrayList<JPanel> panels = new ArrayList<JPanel>();
JPanel panel = new JPanel();
JPanel sortPane = new JPanel();
int toWrite = 0;
int colorGen = 0;
int comparison = 0;
Random rand = new Random();
public SortFrames()
{
for(int i = 0; i<4;i++)
{
panels.add(new JPanel());
}
for(JPanel p: panels)
{
toWrite = rand.nextInt(13);
colorGen = rand.nextInt(2);
p.add(new JLabel());
JLabel lblToSet = (JLabel)p.getComponent(0);
if(colorGen == 0)
{
p.setBackground(Color.BLACK);
lblToSet.setForeground(Color.WHITE);
}
if(colorGen == 1)
{
p.setBackground(Color.WHITE);
lblToSet.setForeground(Color.BLACK);
}
if(toWrite != 12){lblToSet.setText("" +toWrite);}
if(toWrite == 12){lblToSet.setText("-");}
p.setPreferredSize(new Dimension(30, 30));
panel.add(p);
}
sortMethod();
for(JPanel p: panels)
{
panel.add(p);
panel.revalidate();
}
add(panel);
panel.setPreferredSize(new Dimension(300, 300));
setPreferredSize(new Dimension(300, 300));
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
pack();
setLocationRelativeTo(null);
}
public void sortMethod()
{
for(int i = 0; i<(panels.size());i++)
{
for(int j = i+1; j<(panels.size());j++)
{
JLabel one = (JLabel)(panels.get(i)).getComponent(0);
JLabel two = (JLabel)(panels.get(j)).getComponent(0);
String lblOne = one.getText();
String lblTwo = two.getText();
if(!lblOne.equals("-") && !lblTwo.equals("-"))
{
int comp1 = Integer.parseInt(lblOne);
int comp2 = Integer.parseInt(lblTwo);
JPanel pnl1 = panels.get(i);
JPanel pnl2 = panels.get(j);
if(comp1 == comp2)
{
if(pnl1.getBackground() == Color.BLACK && pnl2.getBackground() == Color.WHITE)
{
panels.set(i, pnl1);
panels.set(j, pnl2);
}
if(pnl1.getBackground() == Color.WHITE && pnl2.getBackground() == Color.BLACK)
{
panels.set(i, pnl2);
panels.set(j, pnl1);
}
}
if(comp1 != comp2)
{
if(comp1>comp2)
{
panels.set(i, pnl2);
panels.set(j, pnl1);
}
}
}
if(lblOne.equals("-") && !lblTwo.equals("-"))
{
JPanel pnl1 = panels.get(i);
panels.set(rand.nextInt(panels.size()), pnl1);
}
if(!lblOne.equals("-") && lblTwo.equals("-"))
{
JPanel pnl2 = panels.get(j);
panels.set(rand.nextInt(panels.size()), pnl2);
}
}
}
}
public static void main(String args[])
{
new SortFrames();
}
}
I also have another method, which is by using Comparator class which also creates the same problem (this sorts equal numbers based on foreground but still the same as to sort equal numbers based on background so it has no effect on the said issue).
private static class JPanelSort implements Comparator<JPanel>
{
#Override
public int compare(JPanel arg0, JPanel arg1)
{
JLabel one = ((JLabel) arg0.getComponent(0));
JLabel two = ((JLabel) arg1.getComponent(0));
String firstContent = one.getText();
String secondContent = two.getText();
try
{
comparisonRes = Integer.compare(Integer.parseInt(firstContent), Integer.parseInt(secondContent));
if(comparisonRes == 0)
{
if(one.getForeground() == Color.BLACK && two.getForeground() == Color.WHITE)
{
comparisonRes = 1;
}
if(two.getForeground() == Color.BLACK && one.getForeground() == Color.WHITE)
{
comparisonRes = -1;
}
}
}
catch(NumberFormatException e)
{
comparisonRes = 0;
}
return comparisonRes;
}
}
Please tell me your ideas. Thank you.

It's much easier to sort data than to sort JPanels.
Here's mu GUI displaying your numbers.
So, lets create a Java object to hold the card data.
public class DataModel {
private final int number;
private final int colorNumber;
private final Color backgroundColor;
private final Color foregroundColor;
public DataModel(int number, int colorNumber, Color backgroundColor,
Color foregroundColor) {
this.number = number;
this.colorNumber = colorNumber;
this.backgroundColor = backgroundColor;
this.foregroundColor = foregroundColor;
}
public int getNumber() {
return number;
}
public int getColorNumber() {
return colorNumber;
}
public Color getBackgroundColor() {
return backgroundColor;
}
public Color getForegroundColor() {
return foregroundColor;
}
}
Pretty straightforward. We have fields to hold the information and getters to retrieve the information. We can make all the fields final since we're not changing anything once we set the values.
The sort class is pretty simple as well.
public class DataModelComparator implements Comparator<DataModel> {
#Override
public int compare(DataModel o1, DataModel o2) {
if (o1.getNumber() < o2.getNumber()) {
return -1;
} else if (o1.getNumber() > o2.getNumber()) {
return 1;
} else {
if (o1.getColorNumber() < o2.getColorNumber()) {
return -1;
} else if (o1.getColorNumber() > o2.getColorNumber()) {
return 1;
} else {
return 0;
}
}
}
}
Since we keep the color number, sorting by color is as easy as sorting a number.
Now that we've moved the data to it's own List, we can concentrate on creating the GUI.

}

}
The lessons to be learned here are:
Separate the data from the view.
Focus on one part of the problem at a time. Divide and conquer.

Hello I am creating a TicTacToe game for myself to understand Java better

however I am not sure where I am supposed to enter the whoWins() method. Do I enter this method in the actionperformed Method of the buttons or do i need to something different. Please help.

If you really want to do this right, then I suggest making some big changes, some M-V-C type changes:
First and foremost, separate out the logic of the game from the game GUI. This would mean that the code that determines who wins should not be in any code that contains GUI type code. This will be your "model"
Next you should never have GUI code implement listener interfaces, so try to get that out of the GUI and possibly have it go into its own class, the "Control" class.
Finally the GUI or "View" class will concern itself with displaying the model's state and getting input from the user and transmitting this input to the control.

about when to call the win check:
check each time you click 1 of the 9 buttons,
about the flag:
I use 2 flag instead of 1 flag to indicate game over & winner, because in TTT game, draw game is very usual, after play several times, you always get draw game ...
a little suggestion to your code:
when compare string, use equals(), not ==,
define const values in variable, not write it in logic, e.g. 'O' 'X',
don't repeat code, try use logic control to make it short & easy to read & easy to maintain,

how would be implements autosugesion in JTextArea swing

let me if have you anyone answer, this ans. basically required like as google search engine , when we press any key then it would be display suggestion related pressed key.

As you can see I changed the code by making its constructor accept a JTextComponent rather than a JTextField or JTextArea etc.
The problem we are left with is we have to show the pop up JWindow at a different position depending on the JTextComponent passed i.e a JTextField will have autosuggest window pop up at the bottom while JTextArea/JEditorPane etc would have the JWindow pop up under the caret/word.
Have a look at this specific method showPopUpWindow() in AutoSuggestor class:
private void showPopUpWindow() {
autoSuggestionPopUpWindow.getContentPane().add(suggestionsPanel);
autoSuggestionPopUpWindow.setMinimumSize(new Dimension(textComp.getWidth(), 30));
autoSuggestionPopUpWindow.setSize(tW, tH);
autoSuggestionPopUpWindow.setVisible(true);
int windowX = 0;
int windowY = 0;
if (textComp instanceof JTextField) {//calculate x and y for JWindow at bottom of JTextField
windowX = container.getX() + textComp.getX() + 5;
if (suggestionsPanel.getHeight() > autoSuggestionPopUpWindow.getMinimumSize().height) {
windowY = container.getY() + textComp.getY() + textComp.getHeight() + autoSuggestionPopUpWindow.getMinimumSize().height;
} else {
windowY = container.getY() + textComp.getY() + textComp.getHeight() + autoSuggestionPopUpWindow.getHeight();
}
} else {//calculate x and y for JWindow on any JTextComponent using the carets position
Rectangle rect = null;
try {
rect = textComp.getUI().modelToView(textComp, textComp.getCaret().getDot());//get carets position
} catch (BadLocationException ex) {
ex.printStackTrace();
}
windowX = (int) (rect.getX() + 15);
windowY = (int) (rect.getY() + (rect.getHeight() * 3));
}
//show the pop up
autoSuggestionPopUpWindow.setLocation(windowX, windowY);
autoSuggestionPopUpWindow.setMinimumSize(new Dimension(textComp.getWidth(), 30));
autoSuggestionPopUpWindow.revalidate();
autoSuggestionPopUpWindow.repaint();
}
As you can see we check to see what instance the JTextComponent is and if its not a JTextField simply get the caret position (via the Rectangle of the caret) of the JTextComponent and position JWindow pop up from there (underneath the caret in my case).

I can propose my own implementation. It is based on JList shown in JWindow.
As I wanted to use this code for a combo box, I've disabled UP and DOWN keys with keyEvent.consume() call.

JTextField that has inner fields or preformated format, something like the ip field in windows

I want to create a text field that will be for dates and will have dd.mm.YYYY format. Now what I want the user to type only the numbers, not the dots to. So the field would be like:
_ _. _ _ . _ _ _ _
So when the user wants to type the date: 15.05.2010 for example, he will only type the numbers in the sequence 15052010.
Also I would like, when he presses on left or right arrow, the cursor to go from one field (not JTextField, but field in the JTextField) to the next. So lets say I have JTextField with this text in it: 15.05.2010 If the user is on the beginning and he presses the right arrow, the cursor should go to the .05 field.
I hope you understand me because right now I don't have any idea how to make this, or at least how to look for it on google.

Well, here are 4 classes that solve your problem.
In my case its version control but IP address has the same structure and its easy to modify it.
package com.demo.textfield.version;
import javax.swing.text.Document;
/**
* create documents for text fields
*/
public class DocumentsFactory {
private DocumentsFactory() {}
public static Document createIntDocument() {
return createIntDocument(Integer.MAX_VALUE, Integer.MAX_VALUE);
}
public static Document createIntDocument(int maxValue) {
return createIntDocument(maxValue, Integer.MAX_VALUE);
}
public static Document createIntDocument(int maxValue, int maxLength) {
IntDocument intDocument = new IntDocument();
intDocument.setMaxVal(maxValue);
intDocument.setMaxLength(maxLength);
return intDocument;
}
}
in the followed class we define view:
package com.demo.textfield.version;
import java.awt.Component;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
import javax.swing.JPanel;
public class GridbagPanel extends JPanel {
private static final long serialVersionUID = 1L;
public static final Insets NO_INSETS = new Insets(0, 0, 0, 0);
public GridBagConstraints constraints;
private GridBagLayout layout;
public GridbagPanel() {
layout = new GridBagLayout();
constraints = new GridBagConstraints();
constraints.fill = GridBagConstraints.NONE;
constraints.anchor = GridBagConstraints.WEST;
constraints.insets = NO_INSETS;
setLayout(layout);
}
public void setHorizontalFill() {
constraints.fill = GridBagConstraints.HORIZONTAL;
}
public void setNoneFill() {
constraints.fill = GridBagConstraints.NONE;
}
public void add(Component component, int x, int y, int width, int
height, int weightX, int weightY) {
GridBagLayout gbl = (GridBagLayout) getLayout();
gbl.setConstraints(component, constraints);
add(component);
}
public void add(Component component, int x, int y, int width, int height) {
add(component, x, y, width, height, 0, 0);
}
public void setBothFill() {
constraints.fill = GridBagConstraints.BOTH;
}
public void setInsets(Insets insets) {
constraints.insets = insets;
}
}
We use a plain document that contains our main logic (your changes should be here):
package com.demo.textfield.version;
import javax.swing.text.AttributeSet;
import javax.swing.text.BadLocationException;
import javax.swing.text.PlainDocument;
/**
* a class for positive integers
*/
public class IntDocument extends PlainDocument {
/**
*
*/
private static final long serialVersionUID = 1L;
public static final String NUMERIC = "0123456789";
private int maxVal = -1;
private int maxLength = -1;
public IntDocument() {
this.maxVal = -1;
maxVal = Integer.MAX_VALUE;
maxLength = Integer.MAX_VALUE;
}
public void setMaxLength(int maxLength) {
if (maxLength < 0)
throw new IllegalArgumentException("maxLength<0");
this.maxLength = maxLength;
}
public void setMaxVal(int maxVal) {
this.maxVal = maxVal;
}
public void insertString
(int offset, String str, AttributeSet attr)
throws BadLocationException {
if (str == null)
return;
if (str.startsWith(" ") && offset == 0) {
beep();
str = "";
}
if (!isValidForAcceptedCharsPolicy(str))
return;
if (validateLength(offset, str) == false)
return;
if (!isValidForMaxVal(offset, str))
return;
super.insertString(offset, str, attr);
}
public boolean isValidForAcceptedCharsPolicy(String str) {
if (str.equals("")) {
beep();
return false;
}
for (int i = 0; i < str.length(); i++) {
if (NUMERIC.indexOf(String.valueOf(str.charAt(i))) == -1) {
beep();
return false;
}
}
return true;
}
public boolean isValidForMaxVal(int offset, String toAdd) {
String str_temp;
//String str_text = "";
String str1 = "";
String str2 = "";
try {
str1 = getText(0, offset);
str2 = getText(offset, getLength() - offset);
} catch (Exception e) {
e.printStackTrace();
}
int i_value;
str_temp = str1 + toAdd + str2;
//str_temp = str_temp.trim();
i_value = Integer.parseInt(str_temp);
if (i_value > maxVal) {
beep();
return false;
} else
return true;
}
private boolean validateLength(int offset, String toAdd) {
String str_temp;
//String str_text = "";
String str1 = "";
String str2 = "";
try {
str1 = getText(0, offset);
str2 = getText(offset, getLength() - offset);
} catch (Exception e) {
e.printStackTrace();
}
str_temp = str1 + toAdd + str2;
if (maxLength < str_temp.length()) {
beep();
return false;
} else
return true;
}
private void beep() {
//java.awt.Toolkit.getDefaultToolkit().beep();
}
}
And this is last one with main method that implements all above posted code and you get pretty good view. In my case I used list of 4 text fields separated by dot. You can jump from one "window" to another by using arrows or tab or dot or if your number length reached 4. It will work with implementation of FocusAdapter class:
package com.demo.textfield.version;
import java.awt.Color;
import java.awt.Dimension;

import java.awt.event.FocusAdapter;
import java.awt.event.FocusEvent;
