Java Lambda - BiPredicate or example

BiPredicate or returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.


or has the following syntax.

default BiPredicate<T,U> or(BiPredicate<? super T,? super U> other)


The following example shows how to use or.

import java.util.function.BiPredicate;
/*w  ww.  j  av  a2 s  .  c  om*/
public class Main {
  public static void main(String[] args) {
    BiPredicate<Integer, Integer> bi = (x, y) -> x > y;
    BiPredicate<Integer, Integer> eq = (x, y) -> x -2 > y;
    System.out.println(bi.test(2, 3));
    System.out.println(bi.or(eq).test(2, 3));
    System.out.println(bi.or(eq).test(8, 3));

The code above generates the following result.
