What is the reason to use method overriding?
The benefit of overriding is: ability to define a behavior that’s specific to the subclass type, which means a subclass can implement a parent class method based on its requirement.
In object-oriented terms, overriding means to override the functionality of an existing method..
Why we Cannot override static method?
Static methods cannot be overridden because they are not dispatched on the object instance at runtime. The compiler decides which method gets called. Static methods can be overloaded (meaning that you can have the same method name for several methods as long as they have different parameter types).
Can we have 2 main methods in Java?
The answer is no; there can only one “main” method – where “main” means an entry point you can “run”. You can code overloaded versions as in your example, but they can’t be “run”. There can be more than one main method in a single program. But JVM will always calls String argument main() method.
Can we inherit private method in Java?
You can only call a private member method in its definition class. … say() because derived classes can’t inherit private methods from its base class. Only protected and public methods/variables can be inherited and/or overridden.
Can we override static method?
Can we override a static method? No, we cannot override static methods because method overriding is based on dynamic binding at runtime and the static methods are bonded using static binding at compile time. So, we cannot override static methods.
Why is main method static?
Java main() method is always static, so that compiler can call it without the creation of an object or before the creation of an object of the class. … Static method of a class can be called by using the class name only without creating an object of a class.
Can we call method from constructor?
Calling a method using this keyword from a constructor Yes, as mentioned we can call all the members of a class (methods, variables, and constructors) from instance methods or, constructors.
Is it possible to override the main method?
No, we cannot override main method of java because a static method cannot be overridden. The static method in java is associated with class whereas the non-static method is associated with an object.
How do you prevent a method from overriding?
How many ways to prevent method overriding in Java?By making method final in the base class.By making a method static in the base class.By making a method private in the base class.
Can we override method in Java?
When a method in a subclass has the same name, same parameters or signature, and same return type(or sub-type) as a method in its super-class, then the method in the subclass is said to override the method in the super-class. Method overriding is one of the way by which java achieve Run Time Polymorphism.
What is method hiding?
Method hiding means subclass has defined a class method with the same signature as a class method in the superclass. In that case the method of superclass is hidden by the subclass. It signifies that : The version of a method that is executed will NOT be determined by the object that is used to invoke it.
Can we override main method in Java justify with example?
Short answer is NO, we can not override main method in java. Reason is very simple. As main method is static and we know very well that we can not override static methods in Java, hence main method could not be overridden. So what will happen if we will try to override main method in subclass.
