I want to store a record but don't know what to do.
When i start entering the details of a customer, at that time database connectivity is successfully created but I fail to store the data in the database.
The procedure is correct to create the database but I can't enter the details, what can I do?
Here is the code:

First of all to insert values in database, you should use executeUpdate() method.
And this method does not return any ResultSet.
So Change your code
PreparedStatement ps = con.prepareStatement("insert into Customer values(?,?,?,?)");
ps.setString(1,textFieldId.getText());
ps.setString(2,textFieldName.getText());
ps.setString(3,textFieldContactNo.getText());
ps.setString(4,combo.getName());
ps.executeUpdate();

I tried to make a simple programming that allows student's data to be added, updated, deleted and viewed for my assignments. I'm already stuck at adding part. What is the correct syntax /code to use in order to insert data into the database?
I'm using Eclipse IDE software and XAMPP for this programming.

jTextField.setText(String.valueOf(UserID);
//This make jTextField not editable
jTextField.setEditable(false);
So, this is a program in swing for implementing a search functionality. It runs perfectly well. No problems there. My requirement is to make the search results appear beneath the same page. In this code, I have made the results to appear in a new Jframe that opens a new window. I basically don't want this. I want to make the search result appear in the same page. So, should I modify the code ? Any form of help is appreciated. :) Thanks !

Do not use Null layout. Use a BorderLayout.
All your search functionality should be in the center panel.
add(mySearchPanel, BorderLayout.CENTER);
Your results should be in the south panel. That way it will not shrink the center panel.
add(myResultsPanel, BorderLayout.SOUTH);
If there is nothing in the south panel, then it will shrink away making it seem like it is not there.
So, going into a little more detail, your l0,l1, and b1 components should go into a panel (say myTopPanel), and be added to the center. Your scroll component should be added to the bottom panel.
setTitle("Search Executive Reports ");
setLayout(new BorderLayout());
myTopPanel.add(l0);
myTopPanel.add(l1);
myTopPanel.add(b1);
add(myTopPanel, BorderLayout.CENTER)
add(scroll, BorderLayout.CENTER)

Probably because your field types, especially customer_id, aren't Strings. Try something like this:
