![]() Now is the correct time to discuss the types of the constructor, so primarily there are two types of constructors in java:Ī constructor that has no parameter is known as the No-argument or Zero argument constructor. instructions) that are executed at the time of Object creation. Like methods, a constructor also contains a collection of statements(i.e. So by far, we have learned constructors are used to initialize the object’s state. Access modifiers can be used in constructor declaration to control its access i.e which other class can call the constructor.A constructor in Java can not be abstract, final, static, or Synchronized. ![]() The constructor(s) of a class must have the same name as the class name in which it resides. ![]() Rules for writing constructors are as follows: When Constructor is called?Įach time an object is created using a new() keyword, at least one constructor (it could be the default constructor) is invoked to assign initial values to the data members of the same class. So constructors are used to assign values to the class variables at the time of object creation, either explicitly done by the programmer or by Java itself (default constructor). But when it comes to creating its object(i.e Box will now exist in the computer’s memory), then can a box be there with no value defined for its dimensions? The answer is N o. If we talk about a box class then it will have some class variables (say length, breadth, and height).
