这么简单的问题还要分,可恶
下面例子比较适合集中处理命令
import java.awt.*;
import java.awt.event.*;
public class Test implements ActionListener
{
public void actionPerformed(ActionEvent e) {
System.out.println("按下了"+((Button)e.getSource()).getText());
}
public static void main(String args[]){
Frame f = new Frame();
Button b = new Button("按钮");
b.addActionListener(this);
f.add(b);
f.setSize(100,100);
f.show();
}
}
import java.awt.*;
import java.awt.event.*;
public class Test
{
public static void main(String args[]){
Frame f = new Frame();
Button b = new Button("按钮");
b.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
System.out.println("按下了");
}
});
f.add(b);
f.setSize(100,100);
f.show();
}
}
