There is no method call size   with array  you can use array length

Integer Array doesn t contain size   or length   method  Try the below code  it ll work  ArrayList contains size   method  String contains length    Since you have used int array    so it will be array length  public class Example        int array      1  99  10000  84849  111  212  314  21  442  455  244  554  22  22  211        public void Printrange              for  int i   0  i  lt  array length  i                  if  array i   gt  100  amp  amp  array i   lt  500                    System out println  numbers with in range    i

I think you are confused between size   and length     1  The reason why size has a parentheses is because list s class is List and it is a class type  So List class can have method size       2  Array s type is int    and it is a primitive type  So we can only use length

Array s has  array length   whereas List has  list size     Replace array size   to array length
