The block:
ivjJComboBox1.addMouseListener(new java.awt.event.MouseAdapter() {
public void mouseClicked(MouseEvent e) {
ivjJComboBox1_mouseClicked(e);
usually should be included in your constructor or init method.
The method:
void ivjJComboBox1_mouseClicked(MouseEvent e){
String s = (String)ivjJComboBox1.getSelectedItem();
System.out.println(s);
should be outside your constructor or init method.
So it should be:
public class yourClassName extends xxxxx implements xxxxx
public yourClassName (...) {
ivjJComboBox1.addMouseListener(new java.awt.event.MouseAdapter() {
public void mouseClicked(MouseEvent e) {
ivjJComboBox1_mouseClicked(e);
void ivjJComboBox1_mouseClicked(MouseEvent e){
String s = (String)ivjJComboBox1.getSelectedItem();
System.out.println(s);
