public class Power {
public static void main (String [] args) throws IOException {
// Create a buffered reader
BufferedReader in = new BufferedReader(

// string for storing a line of input

// Read one integer
// prompt the user:

// read a line of input:

// extract a double:

// compute the cube of n

}
}
This is an example from CSci 1211 course.
