Olá pessoal,
Ao compilar este código no Jbuilder 3 university
package testandoGui1;
import java.awt.;
import java.awt.event.;
public class TestandoGui5 extends Frame implements ActionListener{
String x;
Button b;
Button c;
public void paint(Graphics g)
{if (x != null)
g.drawString(x,100,100);
}
public TestandoGui5()
{ setLayout(new FlowLayout());
b = new Button();
c = new Button();
add(b);
add©;
b.addActionListener(this);
c.addActionListener(this);
setSize(300,300);
show();
}
}
Aparece o seguinte:
error: (6) class testandoGui1. TestandoGui5 should be declared abstract;
it does not define method actionPerformed(java.awt.event.ActionEvent) in
interface java.awt.event.ActionListener.
O que posso fazer?
