I have JComboBox expressed on the Marital Status and there is also JRadioButton expressed about sex
My question is how can I work the hidden box to insert the name of the wife and shows when I have a male and married and when they are female and married box appears to insert the name of husband
Please I need your help
Please go into a bit more depth on what you're trying to do and what you've tried including code. The best would be to post an SSCCE that almost does what you want.
This is the code ,There are JLabel and JTextField to insert the name of the wife but hidden and appears when the condition that the person is a male and married appears to insert wife's name
However, if the condition of the person female and married JLabel and JTextField appears to insert the name of husband

Your class implements ActionListener, but you don't use it. Add an ActionListener to variable "combo" so the actionPerformed(ActionEvent) is fired when you change the marital status. Inside actionPerformed you can start checking things. However, the names textfields and sex radio buttons are local in the constructor. You should move these to fields so you can use them in other methods as well.
Oh, and while you're at it: in some countries gay marriage is allowed so a man that has marital status "Marid" [sic] doesn't always have a wife :). Depending on the country you're in, this might be a fun argument to hand to your teacher :)

Did you mean like this , the problem I face is that I do not know how I work previous comparison in actionlistener

Your radios and combo now have an ActionListener. Now the method actionPerformed(ActionEvent e) is triggered once there is a change in any of those. To check for which component triggered the event you can check the event's source: e.getSource(). You can compare that with any of your components. Problem is that the scope of the components is local to the constructor. You would have to move any component that is accessed through your class to a field. So in short it would look like this:
I left lots of stuff out, but you hopefully get the idea.Code:public class Opengui implements ActionListener {
private JComboBox maritalStatus; //this field is now accessible in the methods of the class
public Opengui() {
maritalStatus = new JComboBox();
maritalStatus.addActionListener(this);
}
public void actionPerformed(ActionEvent e) {
if ( e.getSource() == maritalStatus) {
//perform somethisng with another component
}
}
Good luck.
Thank you for helping this is the code you mean, but what I want to do is when work Action on combo to achieve what I'm asking, which is to show the JLabel and JTextField but does not shown it I do not know why

Here's an example on how to check the contents of a JComboBox: How to Use Combo Boxes (The Java™ Tutorials > Creating a GUI With JFC/Swing > Using Swing Components). Then use the .equals() on the value that you get from getSelectedItem().
Thank you for your help I will try to resolve it this way
