Java program to divide two numbers using recursion

Java program to divide two numbers using recursion

In this tutorial, we will discuss the concept of Java program to divide two numbers using recursion

In this topic, we are going to learn how to divide two numbers using the recursive method in Java language

What is division

The division is a method of splitting a group of things into equal parts. The division is an arithmetic operation inverse of multiplication

It is one of the four basic operation of arithmetic calculation others being addition,subtraction,multiplication

The division of two natural numbers means it is the operation of calculating the number of times one number is contained within one another

 

Java exercise to Divide two numbers

Program to division of two numbers

The program calculates the division of the given two numbers using Java recursive method

Program 1

public class FindDivisionRecWithoutUserinput{

public static void main(String args[]){//main method
int num1=100,num2=5;//variable declaration and initialization
int result=divisionNum(num1,num2);//calling the method
System.out.println("Division of "+num1+" and "+num2+":"+result);

}
static int divisionNum(int x,int y){//recursive method
if (y==0)
{
  return 0;
}
else if (x-y==0){
    return 1;
}
else if (x<y){
    return 0;
}
else{
    return (1+divisionNum(x-y,y));
}
}

}

When the above code is executed, it produces the following result

Division of 100 and 5 :20

 

 

Program to division of two numbers – Entered by user

Program 2

The program allows the user to enter two integer numbers and then it calculates the division of the given numbers using the recursive method in Java language

import java.util.Scanner;
public class FindDivisionRecursion{

public static void main(String args[]){//main method
Scanner scan=new Scanner(System.in);
//create a scanner instance for receives input
// from the user - input from keyboard
System.out.print("Enter the value to num1: ");
//Ask input from the user for num1
int num1=scan.nextInt();
//Reading the value entered by user
System.out.print("Enter the value to num2: ");
//Ask input from the user for num1
int num2=scan.nextInt();
//Reading the value entered by user
int result=divisionNum(num1,num2);//calling the method
System.out.println("Division of "+num1+" and "+num2+":"+result);

}
static int divisionNum(int x,int y){//recursive method
if (y==0)
{
  return 0;
}
else if (x-y==0){
    return 1;
}
else if (x<y){
    return 0;
}
else{
    return (1+divisionNum(x-y,y));
}
}

}

When the above code is executed, it produces the following result

Enter the value to num1: 300
Enter the value to num2: 12
Division of 300 and 12 :25
