Function in java does not end

Question

Hi,

This is my first question, and I'm just programming as a hobby, so keep that in mind when trying to help me, please.

I have a function that tries to read the center point of a crosshair. Something like a positioner in a game. The code is as follows:

public static Point location(BufferedImage image) {
        int pixelLeft;
        int pixelTop;
        Point point = new Point();

        for (int i = Main.RADAR_TOP+1; i < Main.RADAR_BOTTOM; i++) {
            pixelLeft = image.getRGB(Main.RADAR_LEFT+7, i);
            if ((((pixelLeft>>16) & 0xff) > 35 &&
                  ((pixelLeft>>8) & 0xff) > 35 &&
                  ((pixelLeft) & 0xff) > 35)){
                point.y = i;
                break;
            }
        }

        for (int j = Main.RADAR_LEFT+1; j < Main.RADAR_RIGHT; j++) {
            pixelTop = image.getRGB(j, Main.RADAR_TOP+5);
            if ((((pixelTop>>16) & 0xff) > 35 && 
                  ((pixelTop>>8) & 0xff) > 35 && 
                  ((pixelTop) & 0xff) > 35)){
                point.x = j;
                break;
            }
        }

        System.out.println("location: "+point.x+","+point.y);
/**        lastX = point.x;
        lastY = point.y;*/
        return point;
    }

It happens that sometimes this function simply does not return control to the main application. Mostly it gets stuck. Therefore, the last comment in the function is to check. At first I thought that maybe this was due to reading the static members of the class that this function is in, so I commented on them, as you can see at the end. The problem is still happening.

, , case-statement, . "".

Answer 2

, Main.RADAR_TOP Main.RADAR_BOTTOM? Else forloop ( ...)
