## 1. Sum of two numbers(already present) :-

``````
{
public static void main(String[] args)
{
int num1 = 5, num2 = 15, sum;
sum = num1 + num2;

System.out.println("Sum of these numbers: "+sum);
}
}
``````

#### Output:

``````
Sum of these numbers: 20
``````
```

function myFunction1() {
var copyTxt = document.getElementById("1");
copyTxt.select();
document.execCommand("copy");
}
```

## 2. Sum of two numbers using Scanner :-

# The scanner allows us to capture the user input so that we can get the values of both the numbers from user. The program then calculates the sum and displays it.

``````
import java.util.Scanner;
{
public static void main(String[] args)
{
int num1, num2, sum;
Scanner sc = new Scanner(System.in);
System.out.println("Enter First Number: ");
num1 = sc.nextInt();

System.out.println("Enter Second Number: ");
num2 = sc.nextInt();

sc.close();
sum = num1 + num2;
System.out.println("Sum of these numbers: "+sum);
}
}
``````

#### Output:

``````
Enter First Number:
200
Enter Second Number:
300
Sum of these numbers: 500
``````
```

function myFunction2() {
var copyTxt = document.getElementById("2");
copyTxt.select();
document.execCommand("copy");
}
```
