     See in java.util.List

     "The List interface places additional stipulations, beyond those specified in the Collection interface, on the contracts of the iterator, add, remove, equals, and hashCode methods. Declarations for other inherited methods are also included here for convenience."

   • Inheritance in Java(Android Studio)

     Top Answer

     Answered May 23, 2017 · 4 votes

     In Android it's not recommended that you use variables to store data across an application (it's also not possible to do that using inheritance), that is bad practice.

     What you're trying to do:

     Why this is a problem:

     First of all, inheriting this score will not allow you to modify it in any way in a subclass. Java doesn't allow you to override values of an inherited field. See this for info. Secondly, creating an inheritance relationship between classes just to get some data is very futile... Because inheritance will inherit everything from the parent class which is not what you need.

     Solution:

     Instead Android APIs have features like SharedPreferences and SQLite that give you options for storing data.

     Why?

     Because storing this data in SharedPreferences or SQLite can be almost seen as storing it in a global variable for you to use throughout your application whenever you need it. It's storage that gives you read/write whenever you want, and doesn't get destroyed when your application closes.

     Please take a look at this for more information on the storage options Android provides.

   • 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.

   In Java, it is possible to inherit attributes and methods from one class to another. We group the "inheritance concept" into two categories: subclass (child) - the class that inherits from another class. superclass (parent) - the class being inherited from. To inherit from a class, use the extends keyword.

   Inheritance is the process of building a new class based on the features of another existing class. It is used heavily in Java, Python, and other object-oriented languages to increase code reusability and simplify program logic into categorical and hierarchical relationships.

   Mar 17, 2024 · 1. Overview. One of the core principles of Object-Oriented Programming – inheritance – enables us to reuse existing code or extend an existing type. Simply put, in Java, a class can inherit another class and multiple interfaces, while an interface can inherit other interfaces.
