Question

I’m writing my Servlet application and would like to use the following static method which will multiply x and y.

public class Helper {
    private Helper() {
        throw new AssertError();
    }

    public static int mutltiply(int a, int b) {
        int c = a*b;
        return c;
    }
 }

I understand that Servlets are multi threading environment. Is it safe to call such method from the servlet?

should I add synchronize property to this function? My concert is regarding value of c variable under multi threading.

I’m new in Java so this information would be very helpful.

Danny.

As long as you don’t use static fields, I see no problems. But if you’re really creating a method which multiply, maybe you need to rethink some parts of your application.
