Can /prog/ please comment on my code?


class prob3{
   
    static long BigBossPrimeOne;
   
    public static void primeFactor(long n){
    boolean prime = true;
    long n1=0;
    long n2=0;
    for(long i=2;(i<=(n/2))&&(prime!=false);i++)
        if ((n%i)==0){
        prime = false;
        n1=i;
        n2=n/i;   
        }   
    if ((prime==true)&&(n>BigBossPrimeOne))
        BigBossPrimeOne = n;
   
    if (prime==false){
        primeFactor(n1);
        primeFactor(n2);
        }            
    }

    public static void main(String args[]){
 
    primeFactor(600851475143L);
    System.out.println(BigBossPrimeOne);
    }

}

I'm just doing the Euler thing to pass the time and I thought why not post this on /prog/ for some insight.

Using the Java language.

Feel free to give me any advice.

Thanks!

Please don't mind the presentation. It's the first time using Emacs and I was under the clock (did this in 15 minutes).

For such a simple program, there's no need to comment. And commenting every line of code with verbose statements is for amateurs.

Real EXPERT PROGRAMMERS document public APIs, keep their code well-factored and self-documenting using descriptive identifier names, and use comments primarily to provide rational for taking certain approaches or explaining why they're doing something that isn't so obvious. They don't go overboard with comments.
