Here is a java example that accepts two integer from the user and find their sum.

import java.util.*;
class AddNumbers
{
    public static void main(String[] args) 
    {
        Scanner input=new Scanner(System.in);
        System.out.print("Enter first number: ");
        int num1=input.nextInt(); 
        System.out.print("Enter second number: ");
        int num2=input.nextInt();
        int sum=num1+num2;
        System.out.println("Result is: "+sum);
    }
}
