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:在上节实验课时,我运行了此程序,显示是正确的,并有运行结果,不知道为啥,我在自己电脑上,显示很多错误,包括说在C盘下没有库,没有找到原因,下次会继续运行此程序!
