单击后如何重新绘制图像？

Question

我正在制作一个你必须点击一个对象的游戏，如果你点击了右边你得到1分，依此类推。 如果你错过了点击对象，你得到-1分。

现在我想在点击它后重新绘制图像，现在只需点击一下，只有分数会改变。

这是我的代码：

（注意：我把导入器留下了，因为它会比OP中的一团糟）

public class Gamevenster extends JPanel implements Runnable {
        public String Gamestatus = "active";
        private Thread thread;
        //public Main game;

    public int random(int min, int max) {
         int range = (max - min) + 1;     
        return (int)(Math.random() * range) + min;
    }

        public TestComponent() {
            this.addMouseListener(this);
