Java- Variable length argument

class VarArgs {
 public static void main(String[] args) {
  SomeClass sc = new SomeClass();

  System.out.println("Sum: " +
   sc.sum(10, 20, 30, 40));
  System.out.println("Sum: " +
   sc.sum(10, 20));
 }
}

class SomeClass {
 int sum(int... values) {
  int result = 0;
/*common method using for loop type 1*/
  for (int i = 0; i < values.length; i++) {
   result += values[i];
  }

  /* using for loop type 2
for (int value : values) {
   result += value;
  }*/

  return result;
 }
}

Note: Variable length arguments are internally treated as arrays.
