Question

In writing a typical JAVA GUI we often have to often provide certain functions that will never be used in the code to write a function call, What are the most common examples of such functions?

Answer 1

actionPerformed(ActionEvent e); : we will never class this method from our code.. this method automatically invoked when any of the button or other control is clicked or changed

itemStateChanged(ItemEvent e);  we will never class this method from our code.. this method automatically invoked when any of check is checked or unchecked

keyPressed(KeyEvent e);  

keyReleased(KeyEvent e);  

keyTyped(KeyEvent e);  

These key methods will be called when we press/release the keys
