介面的各個圖片，自己做好哦

建立一個窗體

import javax.swing.JFrame;

public class GameFrame extends JFrame {//extends繼承
	GamePanel gp;
//構建GameFrame方法
	public GameFrame(){
		this.setSize(500,500);//
		this.setTitle("推箱子");
		this.setDefaultCloseOperation(EXIT_ON_CLOSE);
	    this.setVisible(true);
	    gp=new GamePanel();
	    this.add(gp);
	    
	}
}

建立一個畫板

//構建畫布
import java.awt.Graphics;

import javax.swing.JPanel;
//遊戲畫板
public class GamePanel extends JPanel {
	
	GamePlayer player;
   
	public GamePanel(){
	   player = new GamePlayer(200,300);
   }
 //繪製，重寫
	public void paint(Graphics g){
		player.render(g);
	}
		
	}

建立一個玩家

import java.awt.Graphics;
import java.awt.Image;

import javax.swing.ImageIcon;

public class GamePlayer {
  Image im;//圖片
  int x,y;
  
  //構建方法，初始化屬性值
  public GamePlayer(int x,int y){
	  
	  //載入圖片
	  ImageIcon icon=new ImageIcon("player.png");
	  im=icon.getImage();
	  
	  
	  this.x=x;
	  this.y=y;
  }
  //顯示圖片 渲染
  public void render(Graphics g){
	g.drawImage(im,x,y,null);  
  }
 //玩家移動 
 public void movePlayer(int dx,int dy){
	 x+=dx;
	 y+=dy;
 }
}

執行的Java程式

public class Run {

	public static void main(String[] args) {
       
		GameFrame gf=new GameFrame();//呼叫GameFrame方法
 
	}

}
