Difference Between Method Overloading in Java and Method Overriding in Java

Key Differences

Method Overloading in Java is a feature that permits a class to have multiple methods with the same name, but with different parameters (number, type, or both). On the other hand, Method Overriding in Java is a technique where a subclass provides a specific implementation for a method that is already provided by its superclass.

In the context of Method Overloading in Java, it's important to note that return type doesn't differentiate overloaded methods. Contrastingly, in Method Overriding in Java, the method in the subclass must have the same name, return type, and parameters as the method in the superclass.

Method Overloading in Java enhances the readability of the code since you can use the same name for related actions. In contrast, Method Overriding in Java offers the ability to achieve runtime polymorphism, enabling Java to decide which method to execute based on the object used at runtime.

A key aspect of Method Overloading in Java is that it occurs within the same class. On the flip side, Method Overriding in Java always involves two classes: the superclass and its subclass.

For Method Overloading in Java, the methods can have the same or different access modifiers. In contrast, for Method Overriding in Java, the overriding method cannot have a more restrictive access modifier than the overridden method in the superclass.

Method Overriding in Java

Method Overriding in Java doesn't allow a more restrictive access modifier.
A public method in a superclass can't be overridden as private in a subclass.

Method Overloading in Java

Method Overloading in Java doesn't consider return types for differentiation.
Int add(int a, int b) and double add(double a, double b) are valid overloaded methods.

Method Overriding in Java

Method Overriding in Java mandates the use of the @Override annotation for clarity.
Using @Override before the move() method in Car indicates it's overriding the superclass method.

Method Overriding in Java

Method Overriding in Java is when a subclass provides a specific implementation of a superclass method.
