Difference Between Overloading and Overriding

Method Overloading: To determine, method overloading in Online Java Projects means providing two separate methods in a class with the same name but various arguments. In fact, the method return type may or may not be different that can reuse the same method name.

Method Overloading Rules

As a matter of fact, there are certain rules to follow such as

Two methods will be treated as overloaded if both follow the mandatory rules such as

• both have the same method name
• At the same time, both have a different argument list

As well as, if both methods follow the above mandatory rules, then they may or may not

• have different return types
• It have different access modifiers

Method Overriding: To evaluate , it means defining a method in a child class which is already defined in the parent class with the same method signature such as same name. As well as, arguments and return in Java final year projects.

Method Overriding Rules

Similarly, it has some mandatory and optional rules need to follow to override a method.

• Have the same method name
• Must have the same arguments
• Have the same return type
• Must not have a restrictive access modifier
• It must not throw broader checked exceptions

As well as, if both overriding methods follow the above mandatory rules, then they

• Have a less restrictive access modifier
• Throw fewer or narrower checked exceptions or unchecked exception
