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...

Nov 8, 2023 · The super keyword is used to access properties on an object literal or class's [[Prototype]], or invoke a superclass's constructor. The super.prop and super[expr] expressions are valid in any method definition in both classes and object literals. The super(...args) expression is valid in class constructors.
The super() builtin returns a proxy object (temporary object of the superclass) that allows us to access methods of the base class. We will learn about Python super() in detail with the help of examples in this tutorial.
