ObjLongConsumer Interface is a part of the java.util.function package which is introduced in Java 8. It is an in-built Functional Interface. This function expects an object-valued and a long-valued argument as input but produces no output. In this post, we are going to see several implementations of ObjLongConsumer Interface by using different examples.

Look at ObjLongConsumer Javadoc description below:
ObjLongConsumer Interface contains following method:
accept
Let’s discuss this method:
accept
This method performs operation on the given argument and return no result.
1 | void accept(T t, long value); |
Below is an example to demonstrate accept() method:
Example 1. with Integer
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | import java.util.function.ObjLongConsumer; public class ObjLongConsumerInterfaceJava8Example1 { public static void main(String args[]) { System.out.println("Ex. 1 - ObjLongConsumer - Integer example \n"); ObjLongConsumer <Integer> objLongConsumberObj = (t, value) -> System.out.println(t * value); objLongConsumberObj.accept(5, 10 L); } } |
Example 2. with String
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | import java.util.function.ObjLongConsumer; public class ObjLongConsumerInterfaceJava8Example2 { public static void main(String args[]) { System.out.println("Ex. 2 - ObjLongConsumer - String example \n"); ObjLongConsumer <String> ObjLongConsumberObj = (t, value) -> { if (t.length() > value) { System.out.println("String is bigger than the expected value."); } else if (t.length() == value) { System.out.println("String lenght is equal to expected value."); } else { System.out.println("String is shorter than the expected value."); } }; ObjLongConsumberObj.accept("justanordinarywriter.com", 15 L); ObjLongConsumberObj.accept("techndeck.com", (long) 15); } } |
