    help me please


    import java.util.Scanner;
     
    public class FractionTester {
     
        public static void main(String[] args) {
            MixedFraction operand1, operand2;

            operand2 = enterFractionValue("fraction 2: ");
     
            // place code below
     
        }
     
     
        private static MixedFraction enterFractionValue(String operand) {
        	Scanner keyboard = new Scanner(System.in);
        	System.out.println("Form of " + operand);
        	System.out.println("   (a) Fraction: whole value");
        	System.out.println("   (b) Fraction: with numerator and denominator");
        	System.out.println("   (c) Mixed Fraction");
        	char choice;
        	do {
        		System.out.println("Enter choice: ");
        		choice = Character.toLowerCase(keyboard.nextLine().charAt(0));
        	} while (choice != 'a' && choice != 'b' && choice != 'c');
        	System.out.println();
     
        	MixedFraction f;
        	switch(choice){
        		case 'a':

        			break;

    Default Re: Mixed Fraction JAVA
