     You need to add the check when the value is set, which in this case happens in the constructor of InterestFreeDeposit. The question is how you want to react when the value is below 10. You could throw an IllegalArgumentException:

     public InterestFreeDeposit(String owner, double balance, int accountNumber, double interestRate) { super(owner, balance, accountNumber, interestRate); if(balance < 10){ throw new IllegalArgumentException("balance must be at least 10"); }}

     The problem with this approach is that IllegalArgumentException is an unchecked exception, meaning that the caller of the constructor is not forced to deal with it if it is thrown.

     They are in memory, but you don't have access to them.

     Example:

     class A{ private int foo;- public int getFoo( ) { return foo; } ...}class B extends A{ ...}

     Every instance of class B does, in fact, contain an integer foo under the hood.

     But, you cannot access it directly, because it is declared private. You can access it indirectly, via the getFoo method, because that one is public.

   • Inheritance in Java

     Java, Inheritance is an important pillar of OOP(Object-Oriented Programming). It is the mechanism in Java by which one class is allowed to inherit the features(fields and methods) of another class. In Java, Inheritance means creating new classes based on existing ones. A class that inherits from another class can reuse the methods and fields of that class. In addition, you can add new fields and methods to your current class as well.  

     Why Do We Need Java Inheritance?

     • Code Reusability: The code written in the Superclass is common to all subclasses. Child classes can directly use the parent class code.
     • Method Overriding: Method Overriding is achievable only through Inheritance. It is one of the ways by which Java achieves Run Time Polymorphism.

   • is-a relationship. In Java, inheritance is an is-a relationship. That is, we use inheritance only if there exists an is-a relationship between two classes.
   • Method Overriding in Java Inheritance. In Example 1, we see the object of the subclass can access the method of the superclass. However, if the same method is present in both the superclass and subclass, what will happen?
   • super Keyword in Java Inheritance. Previously we saw that the same method in the subclass overrides the method in superclass. In such a situation, the super keyword is used to call the method of the parent class from the method of the child class.
   • protected Members in Inheritance. In Java, if a class includes protected fields and methods, then these fields and methods are accessible from the subclass of the class.

   How to declare inheritance in Java?

   • To declare inheritance in Java, we simply add extends [superclass] after the subclass’s identifier. Here’s an example of a class Car that inherits from base class Vehicle using private strings and getter/setter methods to achieve encapsulation.
