for (int i = 0; i < Ss.getclass (). Getdeclaredfields (). length;i++) {
System.out.println (Ss.getclass (). Getdeclaredfields () [I].getname ());
}
iterates through all the member variables of the object's parent class and takes its value
for (int i = 0; i < Ss.getclass (). Getsuperclass (). Getdeclaredfields (). length;i++) {
