颜色等于另一种颜色,Java

Question

好吧,我在变量C中设置的颜色等于coal1中的变量,但是当通过if语句时,它返回它们不相等.我用打印线调试它,结果对我来说很奇怪.任何帮助将不胜感激!

码

class MyTask extends TimerTask {

    static Color coal1 = new Color(255, 255, 255);
    Robot robot;
    int xRock, yRock;

    MyTask(Robot r, int x, int y) {
        this.robot = r;
        this.xRock = x;
        this.yRock = y;
    }

    public void run() {
        java.awt.Color c = this.robot.getPixelColor(this.xRock, this.yRock);
        System.out.println("c before the if: "+c);
        System.out.println("coal 1 before the if: "+coal1);

        if (c.equals(coal1)) {  //I can not get the c from the other class to compair with coal1
            System.out.println("color is the same");
        } 
        else {
            System.out.println("c after the if: "+ c);
            System.out.println("coal1 after the if: "+coal1);
            System.out.println("color changed");

            //Stop Timer.
            this.cancel();
        }
    }
}

当我跑它时,我得到了

c before the if: java.awt.Color[r=225,g=225,b=225]
coal 1 before the if: java.awt.Color[r=255,g=255,b=255]
c after the if: java.awt.Color[r=225,g=225,b=225]
coal1 after the if: java.awt.Color[r=255,g=255,b=255]
color changed

Answer 1

根据你的输出,他们是不一样的.c红色,绿色和蓝色组件是225,而coal1组件是255.

Color.equals(Color o) 比较在您的情况下不相同的RGB值
