一个简单的按钮布局界面，想简化代码，但为什么都不显示啊
------解决方案--------------------
- Java code
import javax.swing.*;
import java.awt.*;
public class Dog {
public static void main(String [] args){
JFrame frame = new JFrame();
frame.setSize(new Dimension(100,100));
frame.setLocation(10,10);
frame.setVisible(true);
frame.setLayout(new BorderLayout());
String[] s ={"BorderLayout.NORTH","BorderLayout.WEST","BorderLayout.CENTER","BorderLayout.EAST","BorderLayout.SOUTH"};
for(int i = 1; i <= 5; i++){
frame.add(new JButton("button"+ i),s[i-1]);
}
}
}
------解决方案--------------------
- Java code
public static void main(String[] args)
{
JFrame frame = new JFrame();
frame.setSize(new Dimension(100,100));
frame.setLocation(10,10);
frame.setVisible(true);
frame.setLayout(new BorderLayout());
String[] s ={BorderLayout.NORTH,BorderLayout.WEST,BorderLayout.CENTER,BorderLayout.EAST,BorderLayout.SOUTH};
for(int i = 1; i <= 5; i++){
frame.add(new JButton("button"+ i),s[i-1]);
}
}
------解决方案--------------------
frame.setVisible(true);
放在最后试下
- Java code
import javax.swing.*;
import java.awt.*;
public class Dog {
public static void main(String [] args){
JFrame frame = new JFrame();
frame.setSize(new Dimension(100,100));
frame.setLocation(10,10);
frame.setLayout(new BorderLayout());
String[] s ={"BorderLayout.NORTH","BorderLayout.WEST","BorderLayout.CENTER","BorderLayout.EAST","BorderLayout.SOUTH"};
for(int i = 1; i <= 5; i++){
frame.add(new JButton("button"+ i),s[i-1]);
}
frame.setVisible(true);
}
}

frame.add(new JButton("button"+ i),s[i-1]);
}
frame.setVisible(true);
}}

刚刚发现上面的Border的常量用的不对，应该写成这样
- Java code
import javax.swing.*;
import java.awt.*;
public class Dog{
public static void main(String [] args){
JFrame frame = new JFrame();
frame.setSize(new Dimension(100,100));
frame.setLocation(10,10);
frame.setLayout(new BorderLayout());
String[] s ={BorderLayout.NORTH,BorderLayout.WEST,BorderLayout.CENTER,BorderLayout.EAST,BorderLayout.SOUTH};
for(int i = 1; i <= 5; i++){
frame.add(new JButton("button"+ i),s[i-1]);
}
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
------解决方案--------------------
