就是设计一个计算器 一个数加另一个数 点一个按钮后 出答案
我用了3个文本框 1个标签 一个按钮
错误较多
谢谢您了
我的程序：

import java.awt.event.*;
import javax.swing.*;
public class Calculater extends JFrame{
JTextField add1,add2,results;
JLabel plus;
JButton eql;
void buildConstraints(GridBagConstraints gbc,int gx,int gy,int gw,int gh,int wx,int wy)
{
gbc.gridx=gx;
gbc.gridy=gy;
gbc.gridwidth=gw;
gbc.gridheight=gh;
gbc.weightx=wx;
gbc.weighty=wy;
}
public Calculater(){
super("CASIO");
setSize(350,90);
GridBagLayout gb=new GridBagLayout();
GridBagConstraints constraints=new GridBagConstraints();
JPanel pane=new JPanel();

buildConstraints(constraints,0,0,1,1,25,0);
constraints.fill=GridBagConstraints.HORIZONTAL;
constraints.anchor=GridBagConstraints.CENTER;
