How Different is Function Overriding from Overloading? Explain

The video tutorial explains the concept of inheritance in Java, focusing on how a child class can enhance methods from a parent class, specifically the audio system method. It demonstrates function overriding, where the child class method takes precedence over the parent class method when both have the same name and signature. The tutorial also contrasts function overriding with function overloading, highlighting the differences in method signatures and parameters. This foundational knowledge is crucial for understanding object-oriented programming in Java.

What is the primary purpose of inheritance in Java?

• To create a new class without any methods

• To restrict access to certain methods in a class

• To allow a class to inherit methods and properties from another class

• To enable a class to have multiple parent classes

In the context of function overriding, what happens when a method in a child class has the same name and parameters as a method in the parent class?

• The method in the parent class is executed

• The method in the child class is executed

• Both methods are executed

• An error occurs

Which of the following is true about function overriding?

• It allows a child class to replace a method from the parent class

• It requires different method names

• It is the same as function overloading

• It requires different method signatures

What is a key difference between function overriding and function overloading?

• Overriding requires different method names

• Overloading requires different parameters

• Overriding requires different return types

• Overloading requires the same method signature

Why is understanding the difference between overloading and overriding important in Java interviews?

• Because it is rarely asked in interviews

• Because it only applies to non-Java languages

• Because it is a common question in Java OOPs concepts

• Because it is not relevant to Java programming
