将命名参数传递给方法

class AllTheColorsOfTheRainbow { private int hue = 0;

int anIntegerRepresentingColors;    

void changeTheHueOfTheColor(int newHue) {
    this.hue = newHue;
}

public int getHue(){
    return this.hue;
}

}

public class Ex11 { public static void main(String [] args){ AllTheColorsOfTheRainbow a = new AllTheColorsOfTheRainbow(); a.changeTheHueOfTheColor(newHue = 1); System.out.println(a.getHue()); } }

堆栈跟踪：

javac Ex11.java Ex11.java:18: error: cannot find symbol a.changeTheHueOfTheColor(newHue = 1); ^ symbol: variable newHue location: class Ex11 1 error

您能帮助我理解它的含义以及如何纠正它吗？
