Create A Class That Convert Currency

I want to create a class that converts currency. I stored 2 conversion rate as constant (final) variables. In the main method, I ask the user to enter the amount in US dollars that they want to convert. Then I ask the user to enter the currencyType ("Bitcoin" or "Chuck E Cheese").

However I am stuck in the while loop:

I want to use a while loop that basically does this: If the user entered anything else ( not Bitcoin or Chuck E Chesse), then tell the user to try again, and keep reading Strings until they enter a correct currency type. If the user 3 consecutive incorrect currency types, then exit the program.

Take a look at what I have so far.. when I run the program it does not quite do what I want it to do Also, there's something wrong with one of my if statements and I want to figure out how to fix it.

Java Code:

import java.util.Scanner;
public class CurrencyConverter
{
public static void main(String[] args)
{
System.out.println("----------------------------------");
System.out.println(" Currency Converter");
System.out.println("----------------------------------");

[Code]...

This is how I want my project to look like:
