Getting error as following..
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
    TextReader cannot be resolved to a type
    TextReader cannot be resolved to a type

    at TestCourseGrade.main(TestCourseGrade.java:15)

I am learning java out of a mercer book. he has some pre written code i copied to the working folder. code was named TextReader.java.

I am using eclispe to code and compile in. the code i am writing is a simple prog, which follows.
import TextReader;
public class TestCourseGrade
{
    public static void main (String[] args)
    {
        double test1 = 0.0;
        double test2 = 0.0;
        double finalExam = 0.0;
        double courseGrade = 0.0;

        System.out.println("This program computes a course grade whe");
        System.out.println("you have entered three requested values");
        System.out.println();

        TextReader keyboard = new TextReader();
        System.out.print("Enter first test:");
        test1 = keyboard.readDouble();

        System.out.print("Enter second test:");
        test2 = keyboard.readDouble();
        System.out.print("Enter final test:");
        finalExam = keyboard.readDouble();

        courseGrade = (0.25 * test1)
                    + (0.25 * test2)
                    + (0.50 * finalExam);
        System.out.println("Course Grade: " + courseGrade + "%");
    }
}

Its probably something really simple, some how recogizing that the class (class, the other code written that it is calling) its is calling is there.

Im green, probably shows.

The Textreader is probably not part of a package
