Package - java.util.function

January 05, 2020 Java 8

Well you know predicate, function and consumer can only accept one input argument but sometimes we need a two-argument type functional interface in that situation we can use these predefined functional interfaces.

BiPredicate
BiFunction
BiConsumer

BiPredicate: It is the same as a predicate interface but the only difference is it takes two input arguments to perform a conditional check.

 interface BiPredicate<T,U> {
   public boolean test(T t, U u);
 }

BiFunction: It is the same as a function predefine functional interface but the only difference is it takes two input arguments to perform some operation.

2
3

 interface BiFunction<T,U,R> {
   public R apply(T t, U u);
 }

BiConsumer: BiConsumer is exactly the same as Consumer except that it will take 2 input arguments

3

 interface BiConsumer<T,U> {
   public void accept(T t, U u);
 }
