我的程序的一部分需要查看屏幕上某个点的颜色是否等于某个颜色，然后执行一个动作。我不知道如何不断检查屏幕上的点以查看颜色是否发生变化。任何帮助将不胜感激！

static Color coal1 = new Color(19, 19, 18); //color i want to match up    

int xRock = gameSquare.x + x_scale; // points on the screen
int yRock = gameSquare.y + y_scale;

java.awt.Color c = robot.getPixelColor(xRock, yRock);//finds the rgb color of the point

if (!c.equals(coal1)){ //this is the part where I am stuck!

}

我希望它继续循环，直到 c 不再等于coal1。提前致谢！

编辑：新问题是我无法通过 c 发送以检查它是否 = 到煤炭 1。

一种方法是使用 javascript。这篇文章可以帮助你如何做到这一点https://stackoverflow.com/a/11506531/1083581

一旦您能够获得所需的 rgb 值，您就可以使用 ajax 请求或 javascript 提交，以便在服务器上进行进一步处理。

java.util.Timer' 的schedule(TimerTask, long, long)方法可能取决于工作。

关于您更新的帖子：
您必须搬家

java.awt.Color c = robot.getPixelColor(xRock, yRock); // gets the color of the point

在run()TimerTask 的方法中。而且由于它需要变量robot,xRock和yRock，因此您必须将它们作为参数传递给自定义构造函数。
例如：

/* In 'lookCoal(); method */
  // timer.schedule(t, 0 2000)   // <-- replace that with this:
  timer.schedule(new MyTask(robot, xRock, yRock), 0, 2000);

/* In 'MyTask' Class */
  // Add the required variables:
  Robot robot;
  int xRock, yRock;

  // Add a constructor like this:
  MyTask(Robot r, int x, int y) {
      this.robot = r;
      this.xRock = x;
      this.yRock = y;
  }

  // Modify the run method, like this:
  public void run() {
      java.awt.Color c = this.robot.getPixelColor(this.xRock, this.yRock);
      ...
