     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

     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.

   • Inheritance in Java - 2 Classes

     It Looks like you're going about initializing the inherited members incorrectly. In java, you can call the constructor of a class' parent class using the super constructor.

     New Constructor:

     public Planets () { super(10, "BLUE");}

     That will call the constructor of the Sun class with those values.

     Or you can have the size and color sent in through the Planet class' constructor:

     public Planets(double size, String color) { super(size, color);}

     Hope this helps!

   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.

   Mar 17, 2024 · 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.

   Nov 20, 2023 · 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.

   Jan 3, 2023 · Inheritance in Java refers to the ability of child classes to inherit or acquire all the non-private properties and behaviors from the parent class. Inheritance is one of the four pillars of object-oriented programming and is used to promote code reusability among the classes in a hierarchy.

   The idea of inheritance is simple but powerful: When you want to create a new class and there is already a class that includes some of the code that you want, you can derive your new class from the existing class. In doing this, you can reuse the fields and methods of the existing class without having to write (and debug!) them yourself.

   Generics, Inheritance, and Subtypes. As you already know, it is possible to assign an object of one type to an object of another type provided that the types are compatible. For example, you can assign an Integer to an Object, since Object is one of Integer 's supertypes: Object someObject = new Object(); Integer someInteger = new Integer(10);
