The program will be doing input and output. Which of the Java packages should be imported?

A good answer might be:

java.io.*;

Reading the User's Response

Here is the program with some additional work done on the "user prompting and looping" aspect: 

import java.io.*;

class evalPoly
{
  public static void main (String[] args ) throws IOException
  {
    BufferedReader userin = ___________________________;
    
    double x;                      // a value to use with the polynomial
    String response = "y";         // "y" or "n"

    while ( response.equals( "y" ) )    
    {
       // get a value for x

       // evaluate the polynomial

       // print out the result

       // ask the user if program should continue
       // the user's answer will be referenced by "response"
       ___________________________;

       response = userin.___________________________;      
    }

  }
}
