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

public class MainFrame extends JFrame {
public void MainFrame () {
setTitle("Game");
setSize(DEFAULT_WIDTH, DEFAULT_HEIGHT);

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
}

public static void main(String[] args) {
new MainFrame ();
}

public static final int DEFAULT_WIDTH = 100;
public static final int DEFAULT_HEIGHT = 100;
private JPanel fieldPanel;//活动场地
}

为啥子运行不起呢？

[afgkidy]

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

public class MainFrame extends JFrame {
	public void MainFrame () {
		setTitle("Game");
		setSize(DEFAULT_WIDTH, DEFAULT_HEIGHT);		
		
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        	setVisible(true);
	}
	
	public static void main(String[] args) {
		new MainFrame ();
	}
	
	public static final int DEFAULT_WIDTH = 100;
	public static final int DEFAULT_HEIGHT = 100;
	private JPanel fieldPanel;}

怎么frame 都不能显示，卡到了！提示下。急救

[imasmallbird]

public void MainFrame () {
        setTitle("Game");
        setSize(DEFAULT_WIDTH, DEFAULT_HEIGHT);        
        
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            setVisible(true);
    }

去掉那个void

[imasmallbird]

你是想在构造函数中初始化一些东西
加上void就不是构造函数了，就会调用你的
默认构造函数，这样，你就等于什么也看不到了～～

我晕，我太大意了。多谢了。

阿门，你把构造方法的void去掉就行了

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

public class MainFrame extends JFrame {
    public MainFrame () {
        setTitle("Game");
        setSize(DEFAULT_WIDTH, DEFAULT_HEIGHT);        
        
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            setVisible(true);
    }
    
    public static void main(String[] args) {
        new MainFrame ();
    }
    
    public static final int DEFAULT_WIDTH = 100;
    public static final int DEFAULT_HEIGHT = 100;
    private JPanel fieldPanel;}
