Thread: Cannot Find symbol error! On new Object

In my program for adding subtractin multiplying and dividing fractions the RationalTest.java file wont complie, the Fraction.java does complie

Any help would be appreciated thanks!

package rationaltest;
 
import java.util.Scanner;
 
public class RationalTest {
 
	public static void main (String args[]) {
 
		Scanner input = new Scanner(System.in);
		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);
                char operation = ' ';
 
                System.out.printf("Enter precision:");
		int Prec = input.nextInt();
 
		do{			
		    System.out.printf("\n1. Add\n2. Subtract\n3. Multiply\n4. Divide\n5. Exit\nChoice:");
		    Choice = input.nextInt();
                    switch (Choice) {
                        case 1: operation = '+'; result = f1.Add(f2); break;
                        case 2: operation = '-'; result = f1.Subtract(f2); break;
                        case 3: operation = '*'; result = f1.Mult(f2); break;
                        case 4: operation = '/'; result = f1.Div(f2); break;
                    }
                    System.out.printf("%s %c %s = %s (%s)\n",f1,operation,f2,result,
                                      result.asDecimal(Prec));

Here are all the errors hope this helps

try using the -d option with javac to tell it where the root of the output class path is:

javac - Java programming language compiler

. should be okay if you don't mind your classes being output to ./rationaltest

I couldn't get javac -d to work.

Describe where the source files are located and where you are issuing the javac command.
With the classes in packages, the classpath must point to the folder containing the package folder.

Thanks you very much everyone I got it fixed
