Arithmetic code - Java

//Sample code from http://download.oracle.com/javase/tutorial/

class ArithmeticDemo {

     public static void main (String[] args){
          int result = 1 + 2; // result is now 3
          System.out.println(result);

          result = result - 1; // result is now 2
          System.out.println(result);

          result = result * 2; // result is now 4
          System.out.println(result);

          result = result / 2; // result is now 2
          System.out.println(result);

          result = result + 8; // result is now 10
          result = result % 7; // result is now 3
          System.out.println(result);
     }
}
