import java.awt.*;
import java.awt.event.*;
class JiSuanQi implements ActionListener{
Frame f=new Frame("计算器");
Panel p=new Panel();
Panel p1=new Panel();
Panel p2=new Panel();
Button b=new Button("x+y");
Button b1=new Button("x-y");
Button b2=new Button("清除");
Lable Lbx=new lable("x");
Lable lby=new Lable("y");
TextField tfx=new TextField(4);
TextField tfy=new TextField(4);
TextArea ta=new TextArea();
Font ft=new Font("宋体",Font.BOLD,18);
GridLayout g1=new GridLayout(4,1);
GridLayout g2=new GridLayout(4,1);
double x,y,sum;
public static void main(String[] args){
JiSuanQi ji=new JiSuanQi();
ji.go();
}
public void go(){
b.setFont(ft);
b1.setFont(ft);
b2.setFont(ft);
lbx.setAlignment(Label.CENTER);
lby.setAlignment(Label.CENTER);
lbx.setFont(f

Lable 改为 Label

p1.set.Layout(g2); 改为 p1.setLayout(g2);

lbx.setAlignment(Label.CENTER); 改为 Lbx.setAlignment(Label.CENTER);

String s = ae.get.getActionCommand(); 改为 String s = ae.getActionCommand();

f.setVisible(ture); f.setVisible(true);

没有错误的代码
