Cannot Find symbol error!

In my program for adding subtractin multiplying and dividing fractions the RationalTest.java file wont complie, the Fraction.java does complie
I get the compile error in the RationalTest.java pointing at all the F's on these lines: 21,22,23

Any help would be appreciated thanks!

Code:

package rationaltest;

public class RationalTest {

                int Choice, Num1, Num2, Den1, Den2;
               
                System.out.printf("Enter numerator 1:");
                Num1 = input.nextInt();
                System.out.printf("Enter denominator 1:");
                Den1 = input.nextInt();
                System.out.printf("Enter numerator 2:");
                Num2 = input.nextInt();
                System.out.printf("Enter denominator 2:");
                Den2 = input.nextInt();

                Fraction f1 = new Fraction(Num1, Den1);
                Fraction f2 = new Fraction(Num2, Den2);
                Fraction result = new Fraction(1,1);

                    Choice = input.nextInt();
                    switch (Choice) {

Delete any .class files that may be left over from a previous compile. Then recompile the classes.

db

I deleted all my previous .class files and recomplied getting the same errors..

Copy and paste the errors here.

Here are all the errors hope this helps

Did you compile Fraction first?

Are the .java files in a folder named rationaltest?

db

Yes I compiled Fraction.java first, Even if i delete all the class files and recompile Fraction frist I still get same errors when compiling RationalTest.java

No their in a folder called Rational2

I moved the files to a new folder and named it RationalTest, and recomiplied with out sucuess im getting the same error.

Your package name is rationaltest, not RationalTest. The folder name has to match the package name and you have to compile from the package root: the folder that contains the rationaltest folder.

You need to go through this Lesson: Packages (The Java™ Tutorials > Learning the Java Language)

Thank you very much i got it fixed
