Java.util.function.LongBinaryOperator interface with Examples

The LongBinaryOperator interface was introduced in Java 8. It represents an operation on two long values and returns the result as a long value. It is a functional interface and thus can be used as a lambda expression or in a method reference. It is mostly used when the operation needs to be encapsulated from the user.
Methods:
- applyAsLong(): This function takes two long values, performs the required operation and returns the result as a long.
public long applyAsLong(long val1, long val2)
Example to demonstrate LongBinaryOperator interface as a lambda expression .
// Java program to demonstrate LongBinaryOperator  import java.util.function.LongBinaryOperator;  public class LongBinaryOperatorDemo {    public static void main(String[] args)    {          LongBinaryOperator longBinaryOperator = (x, y) ->        {            return x + y;        };          System.out.print("343666 + 547477 = ");        System.out.println(longBinaryOperator                               .applyAsLong(343666, 547477));          LongBinaryOperator longBinaryOperator1 = (x, y) ->        {            return x * y;        };        System.out.print("343666 * 547477 = ");        System.out.println(longBinaryOperator1                               .applyAsLong(343666, 547477));    }} |
Output:
343666 + 547477 = 891143 343666 * 547477 = 188149230682
