Write a method called power the computes xn where x and n and positive integers. The method has two integer parameters and returns a value of type long.

What will be an ideal response?

/** x and n are nonnegative integers */
public long power(int x, int n)
{
long result = 1;
/** check for positive numbers */
if((x >= 0) && (n >= 0))
{
/** raise x to the nth power */
for(int i = n; i > 0; i--)
result *= x;
}
else
{
result = 0;
System.out.println("Fatal error.......positive integers required!");
}
return result;
}
