Example

The following example shows how to use DoubleToIntFunction.

import java.util.function.DoubleToIntFunction;
/* ww  w. jav a 2s  .  c o m*/
public class Main {

  public static void main(String[] args) {
    DoubleToIntFunction df = (x) -> {return (int)x+2;};

   
    System.out.println(df.applyAsInt(3.14));
