Yes. Any base class method that is declared virtual can be overridden by a derived class. Overriding a method that is not declared virtual can still be called, but will not be called polymorphically. That is, if you call the base class method, the base class method will execute, not the override. To call a non-virtual override you must call it explicitly.

What is the difference between overloading and overriding methods in object?
Here are some of the most common differences between both of them. If you are working in Java for more than 1 year, you might be familiar with all of them but any way its good revision: 1) First and major difference between Overloading and Overriding is that former occur during compile time while later occur during runtime. 2) Second difference between Overloading and Overriding is that, you can overload method in same class but you can only override method in sub class. 3) Third difference is that you can overload static method in Java but you can not override static method in Java. In fact when you declare same method in Sub Class it's known as method hiding because it hide super class method instead of overriding it. 4) Overloaded methods are bonded using static binding and Type of reference variable is used, while Overridden method are bonded using dynamic bonding based upon actual Object. 5) Rules of Overloading and Overriding is different in Java. In order to overload a method you need to change its method signature but that is not required for overriding any method in Java.
What is the scope of method overloading and overriding?
Overloading happens when you have multiple methods in the current class that have the same name but different signature. The scope of method overloading is "Within the current class" Overriding happens when your current class extends another class (the parent class) and provides implementation for a method that is already available in the parent class. The scope of method overriding too is "Within the current class"
What is method overloading and constructor overloading explain with?
method overriding :method overriding means redefine methods in sub classes they already defined in the Super classes.method overloading : It means methods with the same name but with a different signature exist in one class
Why you use overloading and overriding?
Overloading the same method name with different number of arguments (and the data types), and perhaps with a different returned data type. The method signatures are different, only the names are the same. Overriding is to change the same method name with different implementation (the method body). The method signature stays the same.
Is constructor overloading same as method overloading.yes or no. explain?
yes,because in constructor overloading constructor have same and different parameter list. In method overloading method have same name and different parameter list.

Is it possible to do method overloading and overriding at a time?
no we cannot do both at the same time because overloading requires different arguments and overriding dosenot
How you compare and contrast overloading and overriding methods in java?
Method overloading is when you have multiple methods in a class that have the same name but a different signature. Method overriding is similar to method overloading, with a small difference. In overriding, a method in a parent class is overridden in the child class. The method in the child class will have the same signature as that of the parent class. Since the method in the child class has the same signature & name as the method of its parent class, it is termed as overriding. In situations where you may have to explicitly call the parent class method you can use the "super" keyword and for explicitly calling the current objects method you can use the "this" keyword.
What is method overriding and overloading in java?
Overloading is the means by which we can provide two or more different definitions of the same method in the same namespace. Overriding is the means by which a derived class may redefine the meaning of a base class method.
What is the difference between polymorphism and method overloading in java?
The dictionary definition of polymorphism refers to a principle in biology in which an organism or species can have many different forms or stages. This principle can also be applied to object-oriented programming and languages like the Java language. Subclasses of a class can define their own unique behaviors and yet share some of the same functionality of the parent class.Overriding and Overloading are two techiques to achive polymorphism in Java.Method overloading: When a method in a class having the same method name with different arguments is said to be method overloading. Method overriding : When a method in a class having the same method name with same arguments is said to be method overriding.
What is the scope of method overloading and overriding?
Overloading happens when you have multiple methods in the current class that have the same name but different signature. The scope of method overloading is "Within the current class" Overriding happens when your current class extends another class (the parent class) and provides implementation for a method that is already available in the parent class. The scope of method overriding too is "Within the current class"
Explain any 8 difference between overloading and overriding?
Overriding methods that are in the parent class is to redefine them in the current (child) class in a different way. Like if you're extending a class but you don't like the behavior of one method in that class, you can override that method and write your own code. Overloading a method in the current class is defining another copy of the method with different signature. They call them overloaded methods. This is an example of overloaded methods: myMethod(int i, int b){ .... } myMethod(String s) { ... } myMethod(boolean b) {...} Hope that was clear

What is the main difference between inheritance and polymorphism?
The main difference is that: neither of them are related to one another. They have nothing similar between them and are totally different. The only point here is that they are both used in Java which can be stated as a similarity. Inheritance is the feature wherein functionality from one class is available for another class. Polymorphism refers to the feature wherein the same entity exists as multiple items. Ex: method overriding, method overloading etc.
Difference between inheriting a method and overriding?
Inheriting a method means - a class is able to use a method that is declared in its parent class. Because of inheritance we need not re-declare the method in the child class again but still use it as it is. Overriding means re-declaring a method that is already available in the parent class in the child class to alter its features as per the requirement in the child class.
Is constructor overloading same as method overloading.yes or no. explain?
yes,because in constructor overloading constructor have same and different parameter list. In method overloading method have same name and different parameter list.
