# Java program to find Sum of two numbers

This is our second program. It will input two numbers from the user and display their sum on the screen.

Problem:
Input two numbers from the user and display their sum on the screen.

Code:

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18``` ``` /** * @author Hafiz Muhammad Umer */ import java.util.Scanner; public class Sum { public static void main(String[] args) { Scanner input=new Scanner(System.in); int a,b,sum; System.out.print("Enter the first number: "); a=input.nextInt(); System.out.print("Enter the second number: "); b=input.nextInt(); sum=a+b; System.out.println("The sum of "+a+" and "+b+" is "+sum); } } ```

Output:

```Enter the first number: 2
Enter the second number: 3
The sum of 2 and 3 is 5
```

Explanation:

• The line 4 imports the Scanner utility in java. It will be used to create Scanner objects so that we can take input in our program.
• Line 5 defines a class which ends at line 18.
• Line 7 defines the main method which ends at line 17.
• Line 9 creates a Scanner object named input.
• Line 10 defines three int variables.
• From line 11 to 14, two values are taken from the user as input.
• At line 15, the sum of a and b is stored in the variable sum.
• At line 16, the sum is displayed on the screen.
