Why is itemStateChanged on JComboBox is called twice when changed?

Question

I\'m using a JComboBox with an ItemListener on it. When the value is changed, the itemStateChanged event is called twice. The first call, the ItemEvent is showing the origin

Answer 1

Yo can do it like this:

import java.awt.event.*;

jComboBox1.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            System.out.println("Hello");
        }
    });
