![]() ![]() ![]() Constructors may also include parameters of various types. A Constructor’s syntax does not include a return type, since constructors never return a value. The output would be Inside Constructor This is in methodĪ constructor in a class must have the same name as the given class. * Now method will be called explicitly as below. * as it has parameter it will be called as parameterized constructor. * return value so it will be treated as Constructor of the class. Inside Constructor Method Invocation Example /* Constructors cannot be called explicitly, the constructor will be invoked implicitly when the instance of the class is generated( Using a new Keyword) Constructor Invocation Example /*ĬonstructorExample cls = new ConstructorExample() There is a difference between how constructors and methods are called. As per Java naming convention, Method names should be camelcase while Constructor names should start with a capital letter.Ī Method can have the same name as the Class name.The Constructor name must be the same as the Class name while Methods are not restricted.Constructors cannot have a return type( Including void) while Methods require it.Constructors cannot have Non Access Modifiers while Methods can.The syntax of a Constructor is different than a Method as described below. * Method has return type along with Non Access Modifier * Below method will be invoked only when it is invoked implicitly. * return value so it will be treated as Constructor of the class * As below signature has the name as Class name and it doesn't contain any * Here Class name is ConstructorExample, So constructor name needs to be the same. A method is the combination of statements to perform some task and return some value (Optional). This instantiation includes memory allocation and member initialization ( Optional).īy contrast, Methods cannot be used to create an instance of a Class. Purpose (Constructor Vs Method)Ĭonstructors have only one purpose, to create an instance of a Class. A constructor is used in the creation of an object of a class. These differences can be defined in terms of purpose, syntax, and invocation. But there is a big difference between Constructor and Method. Constructors in Java can be seen as a special method in a class. ![]()
