Program to sum of two integer using without + operator in Java
Program to sum of two integer using without + operator in Java
In this article, we will discuss the concept of the Program to sum of two integer using without + operator in Java.
In this post, we are going to learn how to write a program to find the sum of two numbers using without plus operator in Java programming language
Code to find the sum of two numbers
Sum of two integer using minus operator
The program allows the user to enter two integers and then calculates the sum of given numbers using minus operator in Java language
Program 1
//sum of two integer numbers using without + in Java
import java.util.*;
public class SumNumWithoutPlus{
public static void main(String args[]){
int num1,num2;
Scanner sc=new Scanner(System.in);
//scanner class for input
System.out.println("Please Enter the first integer number ");
num1=sc.nextInt();//get input from user for num1
System.out.println("Please Enter the second integer number ");
num2=sc.nextInt();//get input from user for num2
int result =num1-(-num2);//calculate the sum
System.out.println("Sum of two numbers "+num1+" and "+num2+" is: "+result);
}
}
When the above code is executed, it produces the following result
Please Enter the first integer number 225 Please Enter the second integer number 340 Sum of two numbers 225 and 340 is: 565
Sum of two integer using Bitwise operator
The program allows the user to enter two integers and then calculates the sum of given numbers using Bitwise operator in Java language
Program 2
//sum of two integer numbers using bitwise in Java
import java.util.*;
public class SumNumBitwise{
public static void main(String args[]){
int x,y;
Scanner sc=new Scanner(System.in);
//scanner class for input
System.out.println("Please Enter the first integer number ");
int num1=sc.nextInt();//get input from user for num1
System.out.println("Please Enter the second integer number ");
int num2=sc.nextInt();//get input from user for num2
x=num1;
y=num2;
while(num2!=0){
int brw =num1&num2;
num1=num1^num2;
num2=brw<<1;
}
System.out.println("Sum of two numbers "+x+" and "+y+" is: "+num1);
}
}
When the above code is executed, it produces the following result
Please Enter the first integer number 123 Please Enter the second integer number 234 Sum of two numbers 123 and 234 is: 357
Sum of two integer using Bitwise with method
The program allows the user to enter two integers and then calculates the sum of given numbers using Bitwise operator with method in Java language
Program 3
//sum of two integer numbers using bitwise in Java
import java.util.*;
public class SumNumwithoutPlusmethod{
public static void main(String args[]){
int x,y;//variable declaration
Scanner sc=new Scanner(System.in);
//scanner class for input
System.out.println("Please Enter the first integer number ");
int num1=sc.nextInt();//get input from user for num1
System.out.println("Please Enter the second integer number ");
int num2=sc.nextInt();//get input from user for num1
x=num1;//Assign the value of num1 to x
y=num2;//Assign the value of num2 to y
subNum(num1,num2);//Calling the method
}
static void subNum(int num1,int num2){//method definition
while(num2!=0){//calculate sum of two numbers using bitwise operator
int brw =num1&num2;
num1=num1^num2;
num2=brw<<1;
}
System.out.println("Sum of two numbers is: "+num1);
//display output on the screen
}
}
When the above code is executed, it produces the following result
Please Enter the first integer number 125 Please Enter the second integer number 456 Sum of two numbers 125 and 456 is: 581
Sum of two integer using increment, decrement operator
The program allows the user to enter two integers and then calculates the sum of given numbers using increment and decrement operator in Java language.
Program 4
//Sum two integer numbers using bitwise in Java
import java.util.*;
public class SumNum_WithoutPlus2{
public static void main(String args[]){
int x,y;
Scanner sc=new Scanner(System.in);
//scanner class for input
System.out.println("Please Enter the first integer number ");
int num1=sc.nextInt();
System.out.println("Please Enter the second integer number ");
int num2=sc.nextInt();
System.out.println("Sum of two numbers is: "+add(num1,num2));
}
static int add(int num1,int num2){
while(num1>0){
num2++;
num1--;
}
while(num1<0){
num2--;
num1++;
}
return num2;
}
}
When the above code is executed, it produces the following result
Please Enter the first integer number 125 Please Enter the second integer number 250 Sum of two numbers 125 and 250 is: 375
Sum of two integer using for loop
The program allows the user to enter two integers and then calculates the sum of given numbers using for loop in Java language
Program 5
//Sum two integer numbers using bitwise in Java
import java.util.*;
public class SumNum_WithoutPlus3{
public static void main(String args[]){
int x,y;
Scanner sc=new Scanner(System.in);
//scanner class for input
System.out.println("Please Enter the first integer number ");
int num1=sc.nextInt();
System.out.println("Please Enter the second integer number ");
int num2=sc.nextInt();
System.out.println("Sum of two numbers is: "+add(num1,num2));
}//Calling the method
static int add(int num1,int num2){//method definition
int i;
for(i=0; i<num2; i++){
num1++;
}
return num1;
}
}
When the above code is executed, it produces the following result
Please Enter the first integer number 1500 Please Enter the second integer number 2200 Sum of two numbers 1500 and 2200 is: 3700
