I have write a code to find a word in JTextPane. Problem here is when I enter a search word and click on search button it was highlight the all the occurrence of the given search word. I want to Highlight the first occurrence of the word then click on search button shows second occurrence of the way like that. Another one is it was not unHighlight the after search complete when click on text pane.
My code:

If you need just to highlight one word you don't need all the addHighlight() and removeHighlight() calls.
Just figure out the word's offset (and length) and use setSelectionStart()/setSelectionEnd() method of the JTextPane passing the word start and start + length
UPDATE as requested the working code

I am developing a restaurant management system in Java Swing. I have displayed a list of checkboxes dynamically from databases which contains the names of mainstock (table names which contains mainstock items).I have added an ItemListener on each checkbox during the loop.
When I click each checkbox, it popups two JFrame. Why? How could I popup only one JFrame and insert required information?
package test;
public class test extends javax.swing.JFrame {
public static ArrayList<mdetails> list = new ArrayList<mdetails>();
public test() {
initComponents();
Connection con = (Connection) dbconnection.makeconnection();
String sql="select * from mainstock";
try{
Statement st = con.createStatement();
ResultSet rs = st.executeQuery(sql);
while(rs.next()){
String s2=rs.getString("stock_name");
JCheckBox cb = new JCheckBox("New CheckBox");
cb.setText(s2);
cb.setVisible(true);
cb.addItemListener(new ItemListener() {
#Override
public void itemStateChanged(ItemEvent e) {
String name = cb.getActionCommand();
System.out.println(name);
JFrame frame = new JFrame(name);
int stock_id= rmsdao.givestockid(name);
System.out.println(stock_id);
String estimatedplate = JOptionPane.showInputDialog(frame, "Enter the estimated plate of 1 kg"+name);
if(estimatedplate!=null){
list.add(new mdetails(stock_id,estimatedplate));
}
else{
cb.setSelected(false);
}
}
});
jPanel1.add(cb);
jPanel1.validate();

con.close();

I'm not sure what the problem with this code is but whenever I run it I get a java.lang.StackOverflowError. How would I fix it? This is what is displayed in the output console of netbeans:

The very first line in your class Section2 would cause the problem.
You have, Section2 s2Frame = new Section2();, which means, every time an object is created for Section2 you want to create another object of Section2 (which will create another object... and sooooooooo on...)
Hence the stackoverflow exception...
I am a newbie in Java, I need changing the background Color of a progress bar, but really I don't know how to do this
I have a progress bar called "barrita"
I am using Linux Ubuntu and Java 8 and I am using the palette of Swing

I am making a graphical interface in Netbeans where you can put a series of numbers (example: 7 8 5 4 10 13) in the textfield "punten" and when you press the button "ververs" a graphical linechart of all the numbers should appear (in my panel). I made a class "Gui" that extends JFrame with the Textfield, the button and a panel in it. I also made a class "Grafiek" that extends JPanel and that is linked with the panel in my "Gui". The chart would be on the JPanel that is displayed in my JFrame.
The problems that I experience are: the repaint(); command won't go to the paintComponent(Graphics g)-method and my private variables won't change (the length of punt and punti stays 1 no matter what variables I put in my Textbox).
Can somebody please help me, I've been working on this project for days.

One problem I see is that you have declare an instantiated
newJPanel = new Grafiek();
which is the object that you call in the action method
private void verversActionPerformed(java.awt.event.ActionEvent evt) {
newJPanel.verwerkData(punten.getText());
}
But the newJPanel is never added to the frame. The object that looks like it is being added to the frame is
panel = new Grafiek();
which is in the initComponents(). Try changing
newJPanel.verwerkData(punten.getText());
to
panel.verwerkData(punten.getText());
And get rid of the newJpanel because you never use it
In the following code I don't know how to find the average using the Calculate Button. I have managed to read the text in through Text fields for the values but i don't know how to make the program calculate the average and print it in the textfield once the Calculate Button has been clicked.
