我正在用Java编写这个游戏,我只是将基于java.awt的所有窗口相关代码重写为javax.swing.不久之后,我意识到事情现在有点复杂了,所以我做了一些研究,并找到了如何绘制东西,如何设置JFrame的大小等等.但由于某种原因,我的JFrame的大小总是超出我指定的尺寸10个像素.在这种情况下,我希望它是640 x 640像素.

    static GameJComp drawingComp = new GameJComp();

    //Constructor:
    public GameJFrame()
        {
        //Calling super() and setting the title:
        super("Chrononaut");

        //Setting icon image:
        try 
        {
        Image icon = ImageIO.read(getClass().getResource("/icon/icon 1.png"));
        setIconImage(icon);
        }
        catch (IOException e) {}
