import java.util.scanner;

class Sum;

{

public static void main(String[] args)

{

Scanner scr = new Scanner(System.in);

System.out.println("enter first number");

int a = scr.nextInt();

System.out.println("enter second number");

int b = scr.nextInt();

int sum = Math.sum(a,b);

System.out.println("sum of two numbers is-"+sum);

}

}
