If voidwalk is encoded on a creature then another voidwalk is played and removes the creature with voidwalk encoded on it, when the creature returns does it still have the encoded spell on it?

Guest No. Vakyoom, that won't quite work. When he reenters the battlefield after being exiled by this card, he won't have haste. OOP concepts in Java work by letting programmers create components that are reusable in different ways while maintaining security.

Abstraction lets programmers create useful and reusable tools. For example, a programmer can create several different types of objects , which can be variables, functions or data structures. Programmers can also create different classes of objects as ways to define the objects.

For instance, a class of variable might be an address. The class might specify that each address object shall have a name, street, city and zip code. The objects, in this case, might be employee addresses, customer addresses or supplier addresses. Encapsulation lets us reuse functionality without jeopardizing security. For example, we may create a piece of code that calls specific data from a database. It may be useful to reuse that code with other databases or processes. Encapsulation lets us do that while keeping our original data private.

It also lets us alter our original code without breaking it for others who have adopted it in the meantime. Inheritance is another labor-saving Java OOP concept that works by letting a new class adopt the properties of another. We call the inheriting class a subclass or a child class. The original class is often called the parent. We use the keyword extends to define a new class that inherits properties from an old class. Polymorphism in Java works by using a reference to a parent class to affect an object in the child class.

In method overriding , the child class can use the OOP polymorphism concept to override a method of its parent class. This means a single method name might work in different ways depending on what arguments are passed to it. In the example below, encapsulation is demonstrated as an OOP concept in Java. Inheritance can be as easy as using the extends keyword:. For a full tutorial on the different ways to use inheritance in java, see this blog post.

The Employee class inherits from the Person class by using the keyword extends. Here, the child class overrides the parent class. For the full example, see this blog post. The goal of OOP concepts in Java is to save time without sacrificing security and ease of use. The following best practices are all oriented toward advancing that main goal.
