Is constructor is a method?

Constructors are not methods and they don't have any return type. Constructor name should match with class name . Constructor can use any access specifier, they can be declared as private also.

What's the difference between constructors and void methods?

Summary. A void method specifically does not return any data or object. Pragmatically, a constructor does not return anything. ... In order to use the method, getMethod() , you must create an instance of the class Time which is done by constructing its object defined by its constructor.

What is a constructor method?

CONSTRUCTOR is a special method that is used to initialize a newly created object and is called just after the memory is allocated for the object. It can be used to initialize the objects to desired values or default values at the time of object creation.

What is __ init __ in Python?

"__init__" is a reseved method in python classes. It is called as a constructor in object oriented terminology. This method is called when an object is created from a class and it allows the class to initialize the attributes of the class.

Can constructor be private?

Yes, we can declare a constructor as private. If we declare a constructor as private we are not able to create an object of a class. We can use this private constructor in the Singleton Design Pattern.

Is a constructor a void method?

Because constructor function returns the object it creates, not Void.

Can a method call a constructor?

No, you cannot call a constructor from a method. The only place from which you can invoke constructors using “this()” or, “super()” is the first line of another constructor. If you try to invoke constructors explicitly elsewhere, a compile time error will be generated.

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's the biggest difference between constructors and methods?

Constructor is used to initialize an object whereas method is used to exhibits functionality of an object. Constructors are invoked implicitly whereas methods are invoked explicitly.

How many constructors can a class have?

A class can have any number of constructors. If a class have more than one constructor, we call it as the constructor is overloaded.
