The solution approach is straightforward. The method 'power' takes two integers as parameters, 'n' and 'p', representing the base and the exponent respectively. It then checks if either 'n' or 'p' is negative. If so, it throws an Exception with a suitable message. If not, it uses the Math.pow function to calculate and return the result of 'n' raised to the power of 'p'.

public class JavaExceptionHandling {
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);
}
}
