How to generate Action on JComboBox click

[Kunal Lakhani]

I have 3 JComboBox in my form. I want that click on JComboBox should generate event, and not by on its own while the program executes.

I am using ActionListener. Inside the action performed method, i am using 4 ActionEvent object.getSource method, (1 for submit button and other 3 for combo boxes)

if(e.getSource()==ccombobox1){
// code that print a

}

if(e.getSource()==ccombobox2){
// code that print b

}

if(e.getSource()==ccombobox3){
// code that print c

}

As soon as the program executes codes inside this runs and prints 'a','b','c'


I want that when user click comboxbox1, it should print only 'a', similarly 'b' for combobox2, and 'c' for combobox3.

I hope i am able to make the problem understand.

Actually on selection of combobox1, items for combobox2 is generated(from database), and on passing the value of selected item of combobox1 and combobox2 jointly, items for combobox3 is generated.

if(e.getSource()==ccombobox1){
  ccombobox2.removeActionListener(...)
  // code that print a, or
  //code that populates ccombobox2
  ccombobox2.addActionListener(...)
}

if(e.getSource()==ccombobox2){
// code that print b
//same as above, except remove/add for ccombobox3
}

if(e.getSource()==ccombobox3){
// code that print c

}
