Yes, It is allowed to define a method with the same name as that of a class. … Normally the constructor name and class name always the same in Java.
Can a method name be same as class name in Java?
We can have a method name same as a class name in Java but it is not a good practice to do so. … In the below example, a default constructor is called when an object is created and a method with the same name is called using obj.
When a method has same name as class it is called?
The practice of defining two or more methods within the same class that share the same name but have different parameters is called overloading methods. Methods with the same name in a class are called overloaded methods.
Can two classes have the same method name?
Any independent(not connected through some hierarchy) classes can have same method signatures. For your knowledge, Method in a child class with the same signature as of parent is called overridden method.
What happens if constructor of class A is made private?
5. What happens if constructor of class A is made private? Explanation: If we make any class constructor private, we cannot create the instance of that class from outside the class. … Explanation: Final class cannot be inherited.
What is the difference between a constructor and a method?
A Constructor is a block of code that initializes a newly created object. A Method is a collection of statements which returns a value upon its execution. A Constructor can be used to initialize an object. A Method consists of Java code to be executed.
What is it called when more than one function has the same name?
In some programming languages, function overloading or method overloading is the ability to create multiple functions of the same name with different implementations.
What is overriding in Java?
In any object-oriented programming language, Overriding is a feature that allows a subclass or child class to provide a specific implementation of a method that is already provided by one of its super-classes or parent classes. … Method overriding is one of the way by which java achieve Run Time Polymorphism.
Which method is called by the class name in Java?
Qualifying a static call
From outside the defining class, an instance method is called by prefixing it with an object, which is then passed as an implicit parameter to the instance method, eg, inputTF. setText(“”); A static method is called by prefixing it with a class name, eg, Math. max(i,j); .
Is string a class in Java?
Class String. The String class represents character strings. All string literals in Java programs, such as “abc” , are implemented as instances of this class. Strings are constant; their values cannot be changed after they are created.
When a class implements an interface it must?
A class that implements an interface must implement all the methods declared in the interface. The methods must have the exact same signature (name + parameters) as declared in the interface. The class does not need to implement (declare) the variables of an interface. Only the methods.
Can you have a method with the same name as the constructor?
The constructor has the same name as the class and falls under the Type namespace. Method namespace is distinct from Type namespace in Java. So this is technically allowed (and this is not overloading). However, there isn’t ANY valid reason to actually name a method the same as the class name.
