Assuming that the options are stored in arrays, here is the code you want:

String[] sizes = {"L", "XL", "XXL"};
String[] colors = {"red", "green", "black"};
String[] others = {"VALUE_1", "VALUE_2"};

for (int i=0; i < sizes.length; i++){
    for (int j=0; j < colors.length; j++){
        for (int k=0; k < others.length; k++){
            System.out.println(sizes[i] + "." + colors[j] + "." + others[k]);
        }
    }
}

sorry that dose not solve it as if sizes did not come that's mean its length 0 will cause problem – Samir Ghoneim Oct 08 '17 at 08:17
