Here is what I'm doing for this assignment: Create a class called Rational for performing arithmetic with factions. Write a driver program to test your class. Use integer variables to represent the private instance variables of the class, numerator and denominator. These instance variables are not changed by any of the methods other than the constructor method. (Immutable object) The following methods are part of the class. /** Constructor that initialized values of rational number */ public Rational(int numerator, int denominator); /** Add other rational number and this rational number * and return new Rational number. Do not change this rational * number. */ public Rational add(Rational other); /** Substract other rational number from this rational number * and return new Rational number. Do not change this rational * number. */ public Rational subtract(Rational other); /** Print numerator = ... denominator = ... for this rational * number. */ public void print(); /** Print rational number = xx.xx */ public void printfloat(); ------------------------ The test class will be of form: public class TestRational { // main public static void main(String[] args) { // create and test Rational objects here } } ______________________________End of instructions -------------------------------------------------------------------- Here are my programs End of Rational.java End Test Rational.java They both compile, but when I run the TestRational.java it gives me the following error, and I'm wondering if anyone can help explain what it is. This is only my fourth java program I've written, so I'm really new to Java, and to programming. Any help will be appreciated. C:\myjava\assignment2\problem1>java TestRational.java Exception in thread "main" java.lang.NoClassDefFoundError: TestRational/java ------------------

Thanks, I knew that I just had a momentary lapse of memory. Comes from being frustrated working on these programs all weekend. Sometimes it just takes someone else looking. ------------------ Thanks, Dianne
