You want to detect what JComboBox item is selected when you click the JButton?

Easy. Your JButton should have a registered ActionListener that detects mouse clicks. That listener should check the value of the JComboBox. Try it.

But how?Here is one of the codes that i tried.But that is not work correctly.

jcb.addActionListener(this);
jb.addActionListener(this);
public void actionPerformed(ActionEvent e)
{
if(e.getActionCommand().equals("button"))
{

jcb =(JComboBox)e.getSource();

String m=(String)jcb.getSelectedItem();

if(m.equals("x") ) {

System.out.println("vs...");}

if(m.equals("y")){

System.out.println("......"); }
}
}
