In this example, we will see “How to perform division of two numbers in Java 8?”. To achieve that, we are going to use BiFunction interface introduced in Java 8 as part of the functional interfaces and we will see it through several different ways.

Example 1. Java 8 code for division of two integer numbers (hard-coded integers)
import java.util.function.BiFunction;
/**
* Java 8 program for the division of two numbers
*
* @author D.V
*/
public class Calculate_Division_Numbers_Java8_Example1 {
public static void main(String[] args) {
System.out.println("Division of Two Numbers using BiFunction Interface - 'apply' example \n");
int number1 = 40;
int number2 = 12;
BiFunction <Integer, Integer, Integer> biFunctionObj = (i1, i2) - > (i1 / i2);
System.out.println("Division of 2 integer values - " + number1 + " and " + number2 + " is: " + biFunctionObj.apply(number1, number2));
}
}
Output:
Division of Two Numbers using BiFunction Interface - 'apply' example Division of 2 integer values - 40 and 12 is: 3
Example 2. Java 8 code for division of two integer numbers (scanner input)
import java.util.Scanner;
import java.util.function.BiFunction;
/**
* Java 8 program for the division of two numbers
*
* @author D.V
*/
public class Calculate_Division_Numbers_Java8_Example2 {
private static Scanner scanner;
public static void main(String[] args) {
System.out.println("Division of Two Numbers using BiFunction Interface - 'apply' example \n");
scanner = new Scanner(System.in);
System.out.println("\nEnter first number:");
int n1 = scanner.nextInt();
System.out.println("\nEnter second number:");
int n2 = scanner.nextInt();
BiFunction < Integer, Integer, Integer > biFunctionObj = (i1, i2) - > (i1 / i2);
System.out.println("\nDivision of 2 integer values - " + n1 + " by " + n2 + " is: " + biFunctionObj.apply(n1, n2));
}
}
Output:
Division of Two Numbers using BiFunction Interface - 'apply' example Enter first number: 52 Enter second number: 6 Division of 2 integer values - 52 by 6 is: 8
Example 3. Java 8 code for division of two double numbers (scanner input)
import java.util.Scanner;
import java.util.function.BiFunction;
/**
* Java 8 program for the division of two numbers
*
* @author D.V
*/
public class Calculate_Division_Numbers_Java8_Example3 {
private static Scanner scanner;
public static void main(String[] args) {
System.out.println("Division of Two Double Numbers using BiFunction Interface - 'apply' example \n");
scanner = new Scanner(System.in);
System.out.println("\nEnter first number:");
Double n1 = scanner.nextDouble();
System.out.println("\nEnter second number:");
Double n2 = scanner.nextDouble();
BiFunction < Double, Double, Double > biFunctionObj = (i1, i2) - > (i1 / i2);
System.out.println("\nDivision of 2 double values - " + n1 + " by " + n2 + " is: " + biFunctionObj.apply(n1, n2));
}
}
Output:
Division of Two Double Numbers using BiFunction Interface - 'apply' example Enter first number: 56 Enter second number: 9 Division of 2 double values - 56.0 by 9.0 is: 6.222222222222222
