Java Stream How to - Use implied return type

Question

We would like to know how to use implied return type.

Answer

import java.util.Arrays;
/*from  ww w.  j  a  va2s.  c  om*/
public class Main {
   public static void main(String[] args) {
      Integer[] numbers = {1, 2, 3};

      // watch return types, it is implied, no return keyword is necessary
      Arrays.sort(numbers, (i1, i2) -> i2 - i1);

      System.out.println(Arrays.toString(numbers));
   }

}

The code above generates the following result.
