问题描述
这是我的代码一直给我带来的问题.
Here is my code that has been giving the problems.
package ca.rhinoza.game;
import java.awt.BorderLayout;
import java.awt.Canvas;
import java.awt.Dimension;
import javax.swing.JFrame;
public boolean running = false;
public class Game extends Canvas implements Runnable {
private static final long serialVersionUID = 1L;
public static final int WIDTH = 160;
public static final int HEIGHT = WIDTH / 12 * 9;
public static final int SCALE = 3;
public static final String NAME = "Game";
private JFrame frame;
public Game(){
setMinimumSize(new Dimension(WIDTH*SCALE, HEIGHT*SCALE));
setMaximumSize(new Dimension(WIDTH*SCALE, HEIGHT*SCALE));
setPreferredSize(new Dimension(WIDTH*SCALE, HEIGHT*SCALE));
frame = new JFrame(NAME);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new BorderLayout());
frame.add(this, BorderLayout.CENTER);
frame.pack();
frame.setResizable(false);
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
public synchronized void start(){
new Thread(this).start();
}
public synchronized void stop(){
}
public void run() {
}
public static void main(String[] args){
new Game().start();
}
}
我不知道为什么要这么做.
I have no idea why it is doing this.

推荐答案
您要在类外声明一个字段:
You are declaring a field outside of the class:
import java.awt.BorderLayout;
import java.awt.Canvas;
import java.awt.Dimension;
import javax.swing.JFrame;
public boolean running = false; /// <=============== invalid location
public class Game extends Canvas implements Runnable { // <==== class starts here
private static final long serialVersionUID = 1L;
public static final int WIDTH = 160;
public static final int HEIGHT = WIDTH / 12 * 9;
public static final int SCALE = 3;
public static final String NAME = "Game";
...
必须将其放置在类中
import java.awt.BorderLayout;
import java.awt.Canvas;
import java.awt.Dimension;
import javax.swing.JFrame;
public class Game extends Canvas implements Runnable { // <==== class starts here
public boolean running = false; /// <=============== valid location
private static final long serialVersionUID = 1L;
public static final int WIDTH = 160;
public static final int HEIGHT = WIDTH / 12 * 9;
public static final int SCALE = 3;
public static final String NAME = "Game";
...
