Can we override the overloaded method?
Yes, since the overloaded method is a completely different method in the eyes of the compiler.
It depends what you mean.
A method can be an override for an overloaded method in a superclass.
However, you cannot have one method that is both a new overload and an override..

What is advantage of method overloading in Java?
Advantages of method overloading in java Method overloading increases thereadability of the program. Overloaded methods give programmers theflexibility to call a similar method for different types of data. Overloading is also used on constructors to create new objects givendifferent amounts of data.
Can main method be overloaded?
Yes, we can overload the main method in Java, but When we execute the class JVM starts execution with public static void main(String args) method.
What is difference between method overloading and method overriding?
What is Overloading and Overriding? When two or more methods in the same class have the same name but different parameters, it’s called Overloading. When the method signature (name and parameters) are the same in the superclass and the child class, it’s called Overriding.
What is the difference between method overriding and polymorphism?
Overriding is when you call a method on an object and the method in the subclass with the same signature as the one in the superclass is called. Polymorphism is where you are not sure of the objects type at runtime and the most specific method is called.
What is method overloading example?
Method Overloading is a feature that allows a class to have more than one method having the same name, if their argument lists are different. It is similar to constructor overloading in Java, that allows a class to have more than one constructor having different argument lists.
What is the use of method overloading?
Method overloading is a programming technique that allows developers to use the same method name multiple times in the same class, but with different parameters.
What is overloading in OOP?
A major topic in OOP is overloading methods, which lets you define the same method multiple times so that you can call them with different argument lists (a method’s argument list is called its signature). … It’s easy to overload a method; just define it multiple times, each time with a unique signature.
Is polymorphism and overloading same?
-Overloading is when you take an existing method and essentially define it again, but using different parameters which Java sees as a completely different method. -Polymorphism is when you extend the base functionality of a superclass.
Can method overloading based return types?
No, you cannot overload a method based on different return type but same argument type and number in java. same name. different parameters (different type or, different number or both).
Can we prevent overriding a method without using the final modifier?
In short, its not possible to override private and static method in Java. That’s all about 3 ways to prevent a method from being overridden in Java. Remember, though syntactically you can use private, static and final modifier to prevent method overriding, but you should always use final modifier to prevent overriding.
Can you use this () and super () both in a constructor justify the reason with example?
Because if you use this() and super() together in a constructor it will give compile time error. Because this() and super() must be the first executable statement. If you write this() first than super() will become the second statement and vice-versa. That’s why we can’t use this() and super() together.
What is the difference between method overriding and method overloading when working with Java interfaces?
The most basic difference is that overloading is being done in the same class while for overriding base and child classes are required. Overriding is all about giving a specific implementation to the inherited method of parent class.
Why method overloading is considered kind of polymorphism?
In order to implement Polymorphism using method overloading, you need to write many methods with the same name and the same number of parameters but with different data types and implement different behavious in these methods. Now that is also polymorphism. … Method overloading does not change behaviors at runtime.
Can we override static method?
Can we Override static methods in java? We can declare static methods with the same signature in the subclass, but it is not considered overriding as there won’t be any run-time polymorphism. Hence the answer is ‘No’.
What is the difference between polymorphism overloading and overriding?
Overloading is when you have the same function name that takes different parameters. Overriding is when a child class replaces a parent’s method with one of its own (this in iteself does not constitute polymorphism). … This is because any child class can be used where a base class is defined.
What is the point of polymorphism?
Polymorphism is considered one of the important features of Object-Oriented Programming. Polymorphism allows us to perform a single action in different ways. In other words, polymorphism allows you to define one interface and have multiple implementations.
Can method overloading be done in different classes?
Usually, method overloading happens inside a single class, but a method can also be treated as overloaded in the subclass of that class — because the subclass inherits one version of the method from the parent class and then can have another overloaded version in its class definition.
What determines method overloading?
Explanation: Overloading is determined at compile time. Hence, it is also known as compile time polymorphism. … Explanation: Overloading occurs when more than one method with same name but different constructor and also when same signature but different number of parameters and/or parameter type.
