Validating User Input Java

I have a simple command line program that calculates wage and overtime wages.

Everything from the scanner works except the if statement to check if the user's choice is yes or no. Even if the user types yes or no the program runs the last else statement and ends the program. Any help is appreciated.

import java.util.Scanner;
public class WageCalculatorApp {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner input = new Scanner(System.in);

        System.out.print("Base Rate: ");
        double baseRate = input.nextDouble();

        System.out.print("Hours: ");
        int hours = input.nextInt();

        double overtimeMultiplier;
        System.out.print("Would you like to enter an overtime multiplier (yes/no)?");
        String choice = input.nextLine();
        input.nextLine();

        if (choice.equalsIgnoreCase("no")) {
            WageCalculator WC = new WageCalculator(baseRate, hours);
            System.out.printf("Base wage: %.1f%nOvertime Rate: %.1f%nTotal Wage: %.1f",
                    WC.baseWage(), WC.overtimeWage(), WC.totalWage());
        } else if (choice.equalsIgnoreCase("yes")) {
            overtimeMultiplier = input.nextDouble();
            WageCalculator WC1 = new WageCalculator(baseRate, overtimeMultiplier, hours);
            System.out.printf("Base wage: %.1f%nOvertime Rate: %.1f%nTotal Wage: %.1f",
                    WC1.baseWage(), WC1.overtimeWage(), WC1.totalWage());
        } else {
            System.out.println("Choice Not Valid");
        }

    }

}

From a look of it ur formatting isn’t good in the system.out.printf, what is if%? u can’t use if statement in print commands

I actually figured it out. Also, that isn't if%. If you look closely, it's a 1 as in the number one. You can do this do display float and double values a certain length after the decimal point.
