More exception handling problems please :)

Hope this helps..

class MyCalculator{
    public static int power(int n, int p) throws Exception{
        if(n < 0 || p < 0){
            throw new Exception ("n and p should be non-negative");
        } else {
            return ((int)Math.pow(n,p));
        }
    }
}

This problem is shameful, for a lot of reasons, some of them already exposed below.

We can not teach people to use Java with a problem that makes so many basic errors (Class name starting in lowercase, variable with a single letter and in uppercase, which is usually reserved for constants, bad usage of try-catch for controlling the flow of the program, etc.).

I though there was a review process or something for problems, but I have seen a few problems in the Java section that make me think otherwise...

public long power(int n, int p) throws Exception{
    long result;
    if(n==0 && p==0){
        throw new Exception("n and p should not be zero.");
    }
    if(n<0 || p<0){
        throw new Exception("n or p should not be negative.");
    }
         result=(long)Math.pow(n,p);
         return result;
}
