public class TbEvent implements ActionListener {
    
    private JButton addButton;
    private JButton editButton;
    private JButton searchButton;
    private JButton removeButton;
    private JButton ingredientsButton;
    private JButton howToButton;
    private JButton emailButton;
    
    public void ActionPerformed(ActionEvent event) {
        
        try{
            if ( event.getSource() == addButton ) { JOptionPane.showMessageDialog(addButton, "add test") ;}
            else if ( event.getSource() == editButton ) { }    
            else if ( event.getSource() == searchButton ) { }    
            else if ( event.getSource() == removeButton ) { }    
            else if ( event.getSource() == ingredientsButton ) { }    
            else if ( event.getSource() == howToButton ) { }    
            else if ( event.getSource() == emailButton ) { }    
            
        }catch(Exception e){
            
        }
    }

public TbEvent(JButton t1, JButton t2, JButton t3, JButton t4, JButton t5, JButton t7, JButton t8){
    addButton = t1;
    editButton = t2;
    searchButton = t3;
    removeButton = t4;
    ingredientsButton = t5;
    howToButton = t7;
    emailButton = t8;    
}

}

Error desktopapplication1.TbEvent is not abstract and does not override abstract method actionPerformed(java.awt.event.ActionEvent) in java.awt.event.ActionListener TbEvent.java 16


what can i do?

[Jesper de Jong]

Your class TbEvent implements the interface ActionListener.

When you have a (non-abstract) class that implements an interface, you are required to implement all the methods in the interface. One of the methods in interface ActionListener is called actionPerformed, and it takes a java.awt.event.ActionEvent as an argument. You didn't implement that method in your class.

Add a method to class TbEvent:

public void actionPerformed(ActionEvent e) {
	// ... do something
}
