        //
        // This is a challenge, defined by Tim Buchalka
        // This comment part of the code is a part of his Complete Java Master Course from www.udemy.com:
        //
        // https://www.udemy.com/java-the-complete-java-developer-course/
        //
        // I share the challenge text with his permission.
        //
        // A) CHALLENGE OF CLASSES
        //
        // Create a new class for a bank account
        // Create fields for the account number, balance, customer name, email and phone number.
        //
        // Create getters and setters for each field
        // Create two additional methods
        // 1. To allow the customer to deposit funds (this should increment the balance field).
        // 2. To allow the customer to withdraw funds. This should deduct from the balance field,
        // but not allow the withdrawal to complete if their are insufficient funds.
        // You will want to create various code in the Main class (the one created by IntelliJ) to
        // confirm your code is working.
        // Add some System.out.println's in the two methods above as well.
        //
        // A) END OF CHALLENGE OF CLASSES
        //
        // B) CHALLENGE OF CONSTRUCTORS
        //
        // Create a new class VipCustomer
        // it should have 3 fields name, credit limit, and email address.
        // create 3 constructors
        // 1st constructor empty should call the constructor with 3 parameters with default values
        // 2nd constructor should pass on the 2 values it receives and add a default value for the 3rd
        // 3rd constructor should save all fields.
        // create getters only for this using code generation of intellij as setters wont be needed
        // test and confirm it works.
        //
        // B) END OF CHALLENGE OF CONSTRUCTORS
        //
        // TIM BUCHALKA'S JAVA MASTERCLASS CHALLENGE END
        //
        // The code with the solution is made by myself.
