How to extends more than one class

Question

For example if I have a public file() and public edit() in two source files file.java and edit.java and i want to extend both file and edit from the source file menuBar().
Any Help?

Answer 1

thank you for replying
here's my code:
menuBar.java
public class menuBar extends fileMenu
// extending fileMenu to be able to deal with the fileMenu menu.
JMenuBar bar = new JMenuBar();      
public menuBar()
bar.add( fileMenu );
bar.add( editMenu );
fileMenu.java
public class fileMenu extends editMenu {
// extending the editMenu from fileMenu allows me to call editMenu from the JMenuBar
JMenu fileMenu = new JMenu("File");
public fileMenu()
fileMenu.setMnemonic('F');
The previous code worked fine for me, but isn't there another way to do it?
