Pass named parameter to a method

Code:

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());
	}
}

Stack trace:

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

What does this mean, and how can I correct it?

Java does not have named arguments, just positional arguments. You need to pass it without the parameter's name:

a.changeTheHueOfTheColor(1);
