ObjIntConsumer 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 int-valued argument as input but produces no output. In this post, we are going to see several implementations of ObjIntConsumer Interface by using different examples.

Look at ObjIntConsumer Javadoc description below:
ObjIntConsumer Interface contains following method:
accept
Let’s discuss this method:
accept
This method performs operation on the given arguments and return no result.
1 | void accept(T t, int value); |
Below are the several examples 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.ObjIntConsumer; public class ObjIntConsumerInterfaceJava8Example1 { public static void main(String args[]) { System.out.println("Ex. 1 - ObjIntConsumer - Integer example \n"); ObjIntConsumer <Integer> objIntConsumberObj = (t, value) -> System.out.println(t * value); objIntConsumberObj.accept(5, 10); } } |
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.ObjIntConsumer; public class ObjIntConsumerInterfaceJava8Example2 { public static void main(String args[]) { System.out.println("Ex. 2 - ObjIntConsumer - String example \n"); ObjIntConsumer <String> objIntConsumberObj = (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."); } }; objIntConsumberObj.accept("justanordinarywriter.com", 15); objIntConsumberObj.accept("techndeck.com", 15); } } |
Example 3. with ArrayList
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | import java.util.ArrayList; import java.util.List; import java.util.function.ObjIntConsumer; public class ObjIntConsumerInterfaceJava8Example3 { public static void main(String args[]) { System.out.println("Ex. 3 - ObjIntConsumer - list example \n"); ObjIntConsumer <List <Integer>> objIntConsumberObj = (t, value) -> { if (t.contains(value)) { System.out.println("Expected value is present in the string"); } else { System.out.println("Expected value is not present in the string"); } }; List <Integer> listObj = new ArrayList <Integer> (); listObj.add(25); listObj.add(100); listObj.add(73); objIntConsumberObj.accept(listObj, 75); objIntConsumberObj.accept(listObj, 100); } } |
Example 4. with Custom Class Object
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 | import java.util.function.ObjIntConsumer; public class ObjIntConsumerInterfaceJava8Example4 { public static void main(String args[]) { System.out.println("Ex. 4 - ObjIntConsumer - Custom class obj example \n"); ObjIntConsumer <Persons> objIntConsumberObj = (t, value) -> { if (t.getId() == value) { System.out.println("Person with Id: " + t.getId() + " exist." + "\nHis/Her name is: " + t.getName()); } else { System.out.println("\nPerson with Id: " + t.getId() + " does not exist."); } }; Persons p1 = new Persons(25, "Isha Durani"); Persons p2 = new Persons(10, "Gaurangee"); objIntConsumberObj.accept(p1, 25); objIntConsumberObj.accept(p2, 100); } } class Persons { int id; String name; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } Persons(int id, String name) { this.id = id; this.name = name; } } |
