LongUnaryOperator example

Description

LongUnaryOperator represents an operation on a single long-valued operand that produces a long-valued result. This is the primitive type specialization of UnaryOperator for long.

Example

The following example shows how to use LongUnaryOperator.

import java.util.function.LongUnaryOperator;
/*from  ww  w .j a v  a 2  s . c o  m*/
public class Main {

  public static void main(String[] args) {
    LongUnaryOperator i = (l) -> -l;
    
    System.out.println(i.applyAsLong(Long.MAX_VALUE));
  }
}

The code above generates the following result.
