in Java Programs October 13, 2025 Comments Off on Java Program Addition Of Two Numbers – 4 Ways | Programs

Java program to print or calculate addition of two numbers with sample outputs and example programs. Addition of two numbers program is quite a simple one, we do also write the program in five different ways using standard values, command line arguments, classes and objects, without using addition+ operator, method, BufferedReader with sample outputs and code.

How to add numbers?

Well, do you really need an explanation for this? I think not.

Let’s get into the programming part.

Java Program To Print Addition Of Two Numbers

1. Standard Method Function

import java.util.Scanner;
class Add
{
public static void main(String[] arg)
{
int a,b,c;
Scanner sc=new Scanner(System.in);
System.out.println("Enter first number");
a=sc.nextInt();
System.out.println("Enter second number");
b=sc.nextInt();
c=addition(a,b);
System.out.println(" Addition of two numbers is : "+c);
}
static int addition(int x,int y)
{
	return x+y;
}
}

import java.util.Scanner;

class Add

{

public static void main(String[] arg)

{

int a,b,c;

Scanner sc=new Scanner(System.in);

System.out.println("Enter first number");

a=sc.nextInt();

System.out.println("Enter second number");

b=sc.nextInt();

c=addition(a,b);

System.out.println(" Addition of two numbers is : "+c);

}

static int addition(int x,int y)

{

return x+y;

}

Output:

Enter first number
1
Enter second number
2
Addition of two numbers is : 3

Enter first number

Enter second number

Addition of two numbers is : 3

2. Using command line arguments

There you go another method using command line arguments : If you have no idea about what are command line arguments in Java. Do check it out complete guide here – what are command line arguments in java with examples.

import java.util.Scanner;
class Add
{
public static void main(String[] args)
{
int a,b,c;
Scanner sc=new Scanner(System.in);
a=Integer.parseInt(args[0]);
System.out.println("number one is : "+a);
b=Integer.parseInt(args[1]);
System.out.println("number two is : "+b);
c=a+b;
System.out.println("Addition of two numbers is : "+c);
}
}

import java.util.Scanner;

class Add

{

public static void main(String[] args)

{

int a,b,c;

Scanner sc=new Scanner(System.in);

a=Integer.parseInt(args[0]);

System.out.println("number one is : "+a);

b=Integer.parseInt(args[1]);

System.out.println("number two is : "+b);

c=a+b;

System.out.println("Addition of two numbers is : "+c);

}

Output:

>java Add 50 60
number one is : 50
number two is : 60
Addition of two numbers is : 110

>java Add 50 60

number one is : 50

number two is : 60

Addition of two numbers is : 110

3. Using classes and Objects

Print addition of numbers : Another sample program using objects and classes

import java.util.Scanner;
class AdditinCal
{
	int res=0;
	AdditinCal(int x,int y)
	{
	 res=x+y;
	}
}
class Add
{
public static void main(String[] arg)
{
	int a,b;
	Scanner sc=new Scanner(System.in);
	System.out.println("Enter first number");
	a=sc.nextInt();
	System.out.println("Enter second number");
	b=sc.nextInt();
	AdditinCal c=new AdditinCal(a,b);
	System.out.println("Addition of two numbers is : "+c.res);
}
}

import java.util.Scanner;

class AdditinCal

{

int res=0;

AdditinCal(int x,int y)

{

res=x+y;

}

class Add

{

public static void main(String[] arg)

{

int a,b;

Scanner sc=new Scanner(System.in);

System.out.println("Enter first number");

a=sc.nextInt();

System.out.println("Enter second number");

b=sc.nextInt();

AdditinCal c=new AdditinCal(a,b);

System.out.println("Addition of two numbers is : "+c.res);

}

Output:

Enter first number
150
Enter second number
150
Addition of two numbers is : 300

Enter first number

150

Enter second number

150

Addition of two numbers is : 300

4. Without Using Addition+ Operator

You can even write the program without using the + operator here is the sample code – Learn more about what are different types of operators in Java with examples.

import java.util.Scanner;
class Add
{
public static void main(String[] arg)
{
int a,b,c;
Scanner sc=new Scanner(System.in);
System.out.println("Enter first number");
a=sc.nextInt();
System.out.println("Enter second number");
b=sc.nextInt();
while(a--!=0)
{
b++;
}
System.out.println("Addition of two numbers is : "+b);
}
}

import java.util.Scanner;

class Add

{

public static void main(String[] arg)

{

int a,b,c;

Scanner sc=new Scanner(System.in);

System.out.println("Enter first number");

a=sc.nextInt();

System.out.println("Enter second number");

b=sc.nextInt();

while(a--!=0)

{

b++;

}

System.out.println("Addition of two numbers is : "+b);

}

Output:

Enter first number
7
Enter second number
5
Addition of two numbers is : 12

Enter first number

Enter second number

Addition of two numbers is : 12

5. Using Method

Example program #5 : Using method calling to print the addition of two numbers.

import java.util.Scanner;
class Add
{
	int c;
	void addition(int x,int y)
	{
	 c=x+y;
	}
public static void main(String[] arg)
{
int a,b;
Scanner sc=new Scanner(System.in);
System.out.println("Enter first number");
a=sc.nextInt();
System.out.println("Enter second number");
b=sc.nextInt();
Add r=new Add();
r.addition(a,b);
System.out.println("Addition of two numbers is : "+r.c);
}
}

import java.util.Scanner;

class Add

{

int c;

void addition(int x,int y)

{

c=x+y;

}

public static void main(String[] arg)

{

int a,b;

Scanner sc=new Scanner(System.in);

System.out.println("Enter first number");

a=sc.nextInt();

System.out.println("Enter second number");

b=sc.nextInt();

Add r=new Add();

r.addition(a,b);

System.out.println("Addition of two numbers is : "+r.c);

}

Output:

Enter first number
5
Enter second number
1
Addition of two numbers is : 6

Enter first number

Enter second number

Addition of two numbers is : 6

6. Using Buffered Reader

To Print addition of numbers using BufferedReader with sample output.

import java.io.*;
public class AddBuf
{
    public static void main(String[] args) throws IOException
    {
	BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
               System.out.println("Enter first number");
	int x = Integer.parseInt(in.readLine());
               System.out.println("Enter second number");
	int y = Integer.parseInt(in.readLine());
	int z=x+y;
               System.out.println("Addition of two numbers is : "+z);
     }
}

import java.io.*;

public class AddBuf

{

public static void main(String[] args) throws IOException

{

BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

System.out.println("Enter first number");

int x = Integer.parseInt(in.readLine());

System.out.println("Enter second number");

int y = Integer.parseInt(in.readLine());

int z=x+y;

System.out.println("Addition of two numbers is : "+z);

}

Output:

Enter first number
15
Enter second number
15
Addition of two numbers is : 30

Enter first number

Enter second number

Addition of two numbers is : 30
