DoubleUnaryOperator example

Description

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

Example

The following example shows how to use DoubleUnaryOperator.

import java.util.function.DoubleUnaryOperator;
/*from w w w  .java 2 s .  com*/
public class Main {

  public static void main(String[] args) {
    DoubleUnaryOperator dl = (x) -> {return x*x;};
    System.out.println(dl.applyAsDouble(3.14));
  }
}

The code above generates the following result.
