I am taking a college course in Jave and I am very new at this.  I have been trying to compile some code and I keep getting this error:

AverageGrades.java:1: cannot resolve symbol
symbol  : class Scanner
location: package util
import java.util.Scanner;
                 ^
AverageGrades.java:8: cannot resolve symbol

location: class AverageGrades
       Scanner input = new Scanner ( System.in );

import java.util.Scanner;

import javax.swing.*;

 

public class AverageGrades {

   int count;

   public double enterGrades () {

       

       Scanner input = new Scanner ( System.in );

   

       double grade = 0;

       double sum = 0;

       int gradeCounter = 0;

       

     // Enter grades

     System.out.println( "Enter grades (Grade of 0 causes average calculation: ");

     grade = input.nextDouble();

     

     //calculate the total of all grades entered

     

     for (gradeCounter = 0; grade != 0; gradeCounter++ ){

        sum = sum + grade;

        System.out.println( "Enter grades (Grade of 0 causes average calculation: ");

        grade = input.nextDouble();

     }

     count = gradeCounter;

     return sum;

   }

     

   public double aveGrades (double sum ) {

   //calculate the average

 

     double average = 0;     

     average = (double) sum / count;

     System.out.println( "The grade average is " + average );

     return average;

   }

   

     public static void main(String[] args){

     AverageGrades aGrades = new AverageGrades();

     double sum = aGrades.enterGrades();

     System.out.println("Sum : "+sum);

     double average = aGrades.aveGrades(sum);

     System.out.println("Count : "+aGrades.count);

     System.out.println("Average : "+average);

     } // end Main

Scanner was only added in 1.5, make sure you have a 1.5+ version of jdk

even if you have installed multiple version of Java and the older version is set in path  could lead problem.

check java version by executing java -version

if it prints older( < 1.5 ) version of JDK, modify the path variable to refer the latest

With me being new to Java and programming it was difficult to find the right JDK pack.  However on my 3rd download of items from http://java.sun.com/javase/downloads/index.jsp    I finally found the right JDK pack.  Thanks you.
