Oct 24, 2012 · The child class or subclass extends the parent class or super class by adding some capability to the existing capability of the class being extended. super() is how the parent or super class constructor for a Java class is invoked in a derived class.
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.

In Java, super keyword is used to refer to the parent class of a subclass. Here are some of its key characteristics: 1. super is used to call a superclass constructor:When a subclass is created, its constructor must call the constructor of its parent class. This is done using the super() keyword, which calls the constructor of the parent class. 2. ...
It is majorly used in the following contexts as mentioned below: 1. Use of super with Variables 2. Use of super with Methods 3. Use of super with Constructors
This scenario occurs when a derived class and base class have the same data members. In that case, there is a possibility of ambiguity r the JVM. We can understand it more clearly using the following example: Example In the above example, both the base class and subclass have a member maxSpeed. We could access the maxSpeed of the base class in subc...
This is used when we want to call the parent class method. So whenever a parent and child class have the same-named methods then to resolve ambiguity we use the super keyword. This code snippet helps to understand the said usage of the super keyword. Example In the above example, we have seen that if we only call methodmessage() then, the current c...
The super keyword can also be used to access the parent class constructor. One more important thing is that ‘super’ can call both parametric as well as non-parametric constructors depending on the situation. Following is the code snippet to explain the above concept: Example 1 In the above example, we have called the superclass constructor using th...
The super keyword in Javaprovides many advantages in object-oriented programming are as follows: 1. Enables reuse of code: Using the super keyword allows subclasses to inherit functionality from their parent classes, which promotes the reuse of code and reduces duplication. 2. Supports polymorphism: Because subclasses can override methods and acces...

That. Subclass vs. Superclass. What's the Difference? A subclass is a class that is derived from another class, known as the superclass. The subclass inherits all the properties and behaviors of the superclass, allowing it to reuse and extend the functionality of the superclass.
Jul 5, 2024 · Super Class/Parent Class: The class whose features are inherited is known as a superclass(or a base class or a parent class). Sub Class/Child Class: The class that inherits the other class is known as a subclass(or a derived class, extended class, or child class). The subclass can add its own fields and methods in addition to the superclass ...
The super keyword in Java is a reference variable which is used to refer immediate parent class object. Whenever you create the instance of subclass, an instance of parent class is created implicitly which is referred by super reference variable.
