Shoe roshe = new Nike("roshe", 11, "black", "fashion", 129.0, false)
String literals should be enclosed in double quotes.
As for your change in size type, pass int array instead of int
int s[] = {11,12,13};
Shoe roshe = new Nike("roshe", s, "black", "fashion", 129.0, false)
or
Shoe roshe = new Nike("roshe",new int[]{11, 12, 13} , "black", "fashion", 129.0, false)
