In this short tutorial I would like to share with you a simple program that I wrote in Java how to add three numbers. What this program will do is very simple it will ask the user to enter three integer number and then our program will find the some of the three numbers given by our user. I also added a function that will ask the user if the user want to continue run the program again by asking the user do you want to continue. I am using Textpad as my text editor for Java and java scanner library class for input and output function in our program. I hope my simple program will help you understand basic programming concepts using Java.

Sample Output of Our Program
Program Listing
import java.util.Scanner;
class addition
{
public static int add(int a,int b, int c)
{
return(a+b+c);
}
public static void main(String args[])
{
Scanner in = new Scanner(System.in);
char a;
do
{
int num1=0,num2=0,num3=0,solve_addition=0;
System.out.print("\n");
System.out.println("==============================================");
System.out.println("|| <<< ADDITION OF THREE NUMBERS >>> ||");
System.out.println("==============================================");
System.out.print("\n");
System.out.print("Enter First Number :=> ");
num1 = in.nextInt();
System.out.print("Enter Second Number :=> ");
num2 = in.nextInt();
System.out.print("Enter First Number :=> ");
num3 = in.nextInt();
int result = add(num1,num2,num3);
System.out.println("\n");
System.out.println("=======================");
System.out.println("|| DISPLAY RESULT ||");
System.out.println("=======================");
System.out.println("\n");
System.out.print("The sum of " +num1 + " , " + num2 + " and "
+ num3 + " is " + result + ".");
System.out.println("\n\n");
System.out.print("Do you Want To Continue (Y/N) :=> ");
a=in.next().charAt(0);
} while(a=='Y'|| a=='y');
System.out.println("\n");
System.out.println("\t ===== END OF PROGRAM ======");
System.out.println("\n");
}
}
