Again same problem?
This program executes JTextField and JPasswordField.But the problem is I use Eclipse Platform and It shows error in line 43.The error is:
class must implement the inherited abstract method ActionListener.actionPerformed(ActionEvent)
But I've already implement that.And that's why I can't understand what's the actual problem.I've already faced the problem beforr but couldn't solve the problem although I got the help of the forum.Plz help me now.
