Difference Between Overloading and Overriding in Java
In the table provided below, we have mentioned the difference between overloading and overriding in the Java programming language based on the various factors.
Key Differences Between Overloading and Overriding in Java
|Method Overriding||Method Overloading|
|Overriding of the already given method by the parent class.||The readability of the program is enhanced.|
|Overriding needs the same parameters to execute the function call.||In this, parameters must be different.|
|Runtime polymorphism.||Compile-time polymorphism.|
|Multiple class performance.||Same class performance of the method.|
|It occurs between subclass or superclass.||Occur in the same class.|
|It is used to provide better performance.||Does not provide as good of the performance as overriding.|
What is Method Overloading in Java?
Method overloading in Java is used to allow polymorphism on the basis of argument or argument types. It is also known or related to compile-time polymorphism. This return type can not be overloaded. Static methods can be overloaded but arguments shall be different.
Overloading in Java can not be done if the difference between them is the static keyword only. Two methods with different parameters can be overloaded in Java. It is used because it saves the effort of using the same function without defining it over and over again.
What is Method Overriding in Java?
It is also another method to allow polymorphism in the Java programming language. It is used when the parent class or base class already provided the method and we want to implement that method again by overriding it.
A child class calls method will override the parent class method if it is again called the method. In the final method, overriding in Java programming language is not supported.
