Question

我创建了一个随机颜色游戏，部分代码是：

public static void getARandomColor() 
{
    System.out.println();
    System.out.println("Your random color is...");
    // red
    MY_RANDOM = RANDOM_NUMBER.nextInt(COLOR_MAX);
    RED = MY_RANDOM;
    // green
    MY_RANDOM = RANDOM_NUMBER.nextInt(COLOR_MAX);
    GREEN = MY_RANDOM;
    // blue
    MY_RANDOM = RANDOM_NUMBER.nextInt(COLOR_MAX);
    BLUE = MY_RANDOM;
    // combinations...
    System.out.println("Your color is r: " + RED + ", g: " + GREEN
            + ", b: " + BLUE + "!");
    System.out.println();
}

所以所有内容都有效，但是我希望更进一步，在中文之后添加文字＆＃34; System.out.println（＆＃34;你的颜色是r：＆＃34; + RED +＆＃34;，g：＆＃34; + GREEN +＆＃34;，b：＆＃34; + BLUE +＆＃34;！＆＃34;）;＆＃34;成为随机颜色的线。

我认为没有方法可以在java中获取颜色名称。所以你创建了以下方法。

String getColorName(int r, int g, int b){switch(r){case 0: switch(g){
    case 0: switch(b)
            {
            case 0: return "black";
            break;
            case 128: return "Navy";
            break;
            case 255: return "Blue";
            break;
            //continue for all color

            }
    }
    }

您可以参考此颜色名称和RGB值。 enter link description here
