实验十 用户界面设计

import java.awt.*;
import javax.swing.*;

public class JFramedemo extends JFrame {
private Box box;
private Container container;
private JTextField text;
private JPanel panel1,panel2;
private String S1[]={"Backspace","CE","C"};//将计算器上显示的内容存在数组里面
private String S2[]={"1","2","3","+","sqrt","4","5","6","-","%","7","8","9","*","1/x","0","+/-",".","/","="};
public JFramedemo(){
    this.setTitle("计算器显示界面");
    this.setBounds(300,300,500,500);
    container=getContentPane();
    container.setLayout(new FlowLayout());//将内容窗格设置成流式布局
    text=new JTextField(15);
    box=Box.createVerticalBox();
    panel1=new JPanel(new GridLayout(1,3,20,0));
    //panel1.setLayout(new GridLayout(1,3,10,0));
    panel2=new JPanel();
    panel2.setLayout(new GridLayout(4,5,10,10));
    for(int i=0;i<3;i++)//将数组S1的内容加到panel1的Button按钮上
    {
        panel1.add(new JButton(S1[i]));
    }
    for(int j=0;j<20;j++)//将数组S2的内容加到panel2的Button按钮上
    {
        panel2.add(new JButton(S2[j]));
    }
    box.add(text);
    box.add(Box.createVerticalStrut(15));
    box.add(panel1);
    box.add(Box.createVerticalStrut(25));
    box.add(panel2);
    container.add(box);
   pack();//调整窗口的大小，使其适应组件的大小和布局
    setVisible(true);
    this.setDefaultCloseOperation(EXIT_ON_CLOSE);
}
  public static void main(String[] args) {
    new JFramedemo();
    }
}

心得体会

对java不太熟悉，在同学的帮助下完成

了解了java对环境的要求很高

了解了一点框架结构的特点
