设置javax.swing.Timer

Question

好的我正在做一个项目，图像应该随机移动，当用户点击图像时，它应该计算点击它的次数。从那里开始它一直在移动，直到它们x。但是，我犯了一个错误，让图像在点击后移动，所以当程序启动时图像还没有移动。我需要它从程序的开头移动。

附在这里因为无论出于何种原因，堆栈溢出一直说我格式错误。

public class Zombie {

//declare variables 
private int x;
private int y;

private int size;
private Image image;

//constructor 
public Zombie(int xIn, int yIn, String imagePath) {
    x = xIn;
    y = yIn;
    size = Settings.DEFAULT_SIZE;
    setImage(imagePath);
}

//getter for x
public int getX() {
    return x;
}

    this.x = x;
