What will be the output of the following program?

class MarkerInterfaces {

    public static void main(String[] args) {
        System.out.println("G = " + G.PI);
        System.out.println("H = " + H.PI);
        CG cg = new CG();
        System.out.println("cg = " + cg.PI);
        cg.PI *= 2;
        System.out.println("cg = " + cg.PI);
        System.out.println("G = " + G.PI);
    }
}

interface G {

    double PI = 3.14;
}

interface H extends G {

    double PI = 3.145;
}

class CG implements G {

    double PI = 3.1451;
}

	G = 3.14 H = 3.14 cg = 3.14 cg = 3.14 G = 3.14
	G = 3.14 H = 3.14 cg = 3.1451 cg = 6.2902 G = 3.14
	G = 3.14 H = 3.145 cg = 3.1451 cg = 6.2902 G = 3.14
	G = 3.14 H = 3.145 cg = 3.1451 cg = 6.2902 G = 6.2902
	Compilation Error
