How do I locate the instance name for a swing widget?

[Calvin Hwang]

Example
jButton1 = new JButton();
How do I code something for
jButton.???
to return to me the string "jButton1"?
It is the bit of ??? that has me stumped.

Welcome to the Ranch Calvin.
If you mean the name of the instance variable, it can be found out with reflection.
If you mean the name field of awt.Component it can be accessed by getName and setName.

import javax.swing.*;
import java.awt.*;
import java.lang.reflect.*;
public class Test extends JFrame {
  JTextField fieldOne = new JTextField();
 
  public static void main(String[] args) throws Exception {   
    Field[] declared = new Test().getClass().getDeclaredFields();
    System.out.println(declared[0].getName());
    ///////////////////////////////////////////////////////////
    System.out.println(new TextField().getName());
    System.out.println(new JTextField().getName());
  }
}
/*
fieldOne
textfield0
null
*/
