Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.

Usage

From source file:Main.java

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.and(eq).test(2, 3));
    System.out.println(bi.and(eq).test(8, 3));
}
