Java Program: Subtract Two Numbers Using Loops(Examples)

In this tutorial, we will discuss “Java Program: Subtract Two Numbers Using Loops(Examples).”

Subtract Two Numbers

You want to see different ways of subtracting two numbers in Pascal. Let’s go step by step with a few approaches.

In this article, we explore six different methods for multiplying two numbers.

In this tutorial, we’ll walk through how to create a simple Java program that subtracts two numbers using the loops(for, while and so on). While subtraction is typically a straightforward operation, using a loop introduces a slightly different approach that helps reinforce the use of iterative logic in Java. Whether you’re a beginner or brushing up on your Java skills, this example will help you understand how control structures like loops can be used creatively for basic tasks.

Subtract two numbers in Java using for loops

Program 1

// subtract two numbers
//using a for loop

class Subtract_Twonum {
    public static void main(String[] args) {
        int num1=100;
         int num2=50;
         int result=0;
                for(int i=0; i//subtract two numbers using a loop
class Subtraction_Twonum_UsingLoop {
    public static void main(String[] args) {
         int result;
        int num1=150;
         int num2=25;
          result=subtractForMethod(num1,num2);
    System.out.println("Subtraction of two numbers using a for loop with method:" ) ;

        System.out.println(num1 + "-" + num2 + "=" + result);
    }
    
public static int subtractForMethod(int a, int b){
    int result=a;
         for(int i=0; i
When the above code is executed, it produces the following result
Subtraction of two numbers using a for loop with method:
150-25=125
Subtract two numbers in Java using while loops
Program 3
//subtract two numbers using while loop
//import java.util.Scanner;
class Subtraction_Twonum_UsingwhileLoop {
    public static void main(String[] args) {
                
int num1=75;     
int num2=35;

          int res=subtract_While_Method(num1,num2);
          //calling the user drfined method for output
    System.out.println("Subtraction of two numbers using while loop with method:" ) ;

        System.out.println(num1 + "-" + num2 + "=" + res);
    }
    
public static int subtract_While_Method(int a, int b){
    int result=a;
int i=0;
         while( i
When the above code is executed, it produces the following result
Subtraction of two numbers using while loop with method:
75-35=40
Subtract two numbers in Java using while loops with method
Program 4
//subtract two numbers using while loop with method and user input
import java.util.Scanner;
class Subtract_Twonum_Using_whileLoop {
    public static void main(String[] args) {
                
Scanner input_num=new Scanner(System.in);
 System.out.println("Input number to num1:");
         
int num1=input_num.nextInt();

 System.out.println("Input number to num2:");
         
int num2=input_num.nextInt();


          int res=subtract_While_Method(num1,num2);
          //calling the user drfined method for output
    System.out.println("Subtraction of two numbers using while loop with method and user input:" ) ;

        System.out.println(num1 + "-" + num2 + "=" + res);
    }
    
public static int subtract_While_Method(int a, int b){
    int result=a;
int i=0;
         while( i
When the above code is executed, it produces the following result
Input number to num1:
125
Input number to num2:
35
Subtraction of two numbers using while loop with method and user input:
125-35=90
Subtract two numbers in Java using do-while loops
Program 5

int num1=input.nextInt();
 System.out.println("Input second number:");
