What is method hiding?
Java 8Object Oriented ProgrammingProgramming.
When super class and sub class contains same method including parameters and if they are static.
The method in the super class will be hidden by the one that is in the sub class.
This mechanism is known as method hiding..
What is an overloaded function C++?
C++ allows specification of more than one function of the same name in the same scope. These functions are called overloaded functions. Overloaded functions enable you to supply different semantics for a function, depending on the types and number of arguments.
What happens if we override static method?
In short, a static method can be overloaded, but can not be overridden in Java. If you declare, another static method with same signature in derived class than the static method of superclass will be hidden, and any call to that static method in subclass will go to static method declared in that class itself.
Can a constructor be overloaded?
Yes! Java supports constructor overloading. In constructor loading, we create multiple constructors with the same name but with different parameters types or with different no of parameters.
What can be overloaded in C++?
C++ allows you to specify more than one definition for a function name or an operator in the same scope, which is called function overloading and operator overloading respectively.
Which type of function Cannot be overloaded?
Function declarations that differ only by its return type cannot be overloaded with function overloading process. Member function declarations with the same parameters or the same name types cannot be overloaded if any one of them is declared as a static member function.
Can a private method be declared as static?
Yes, we can have private methods or private static methods in an interface in Java 9. We can use these methods to remove the code redundancy. Private methods can be useful or accessible only within that interface only. We can’t access or inherit private methods from one interface to another interface or class.
Are private methods final?
When we use final specifier with a method, the method cannot be overridden in any of the inheriting classes. Methods are made final due to design reasons. Since private methods are inaccessible, they are implicitly final in Java. So adding final specifier to a private method doesn’t add any value.
Can you override private method?
No, a private method cannot be overridden since it is not visible from any other class. You have declared a new method for your subclass that has no relation to the superclass method.
Can static methods be overloaded in C++?
This feature allows different methods to have same name, but different signatures, especially number of input parameters and type of input paramaters. Note that in both C++ and Java, methods cannot be overloaded according to return type. Can we overload static methods? The answer is ‘Yes’.
Can final method be overloaded?
private and final methods can be overloaded but they cannot be overridden. It means a class can have more than one private/final methods of same name but a child class cannot override the private/final methods of their base class.
Can static private final methods be overridden?
No, we cannot override private or static methods in Java. Private methods in Java are not visible to any other class which limits their scope to the class in which they are declared.
Which C++ Cannot be overloaded?
Operators that cannot be overloaded in C++? “.” Member access or dot operator.? “? : ” Ternary or conditional operator.? “::” Scope resolution operator.? “. *” Pointer to member operator.? “ sizeof” The object size operator.? “ typeid” Object type operator.
Why we Cannot override static method?
Overloading is the mechanism of binding the method call with the method body dynamically based on the parameters passed to the method call. Static methods are bonded at compile time using static binding. Therefore, we cannot override static methods in Java.
Can virtual functions be overloaded C++?
In fact, virtual functions, as other functions, CAN be overloaded within the class defining them, in addition to the override option for derived classes. Even for pure virtual functions, they can have multiple signatures in abstract classes!
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. In any Java program, the main() method is the starting point from where compiler starts program execution. So, the compiler needs to call the main() method.
Can static function be overloaded C++?
Some interesting facts about static member functions in C++ 1) static member functions do not have this pointer. 3) Member function declarations with the same name and the name parameter-type-list cannot be overloaded if any of them is a static member function declaration.
Which operator can be overloaded?
Compound assignment operators cannot be explicitly overloaded. However, when you overload a binary operator, the corresponding compound assignment operator, if any, is also implicitly overloaded. For example, += is evaluated using + , which can be overloaded.
