Therefore, it is also known as a no-args constructor. If we don’t define a constructor in a class, then the compiler creates a default constructor(with no arguments) for the class. Output: Student Name: Ashok and Student Id: 101 Default Constructor in Java:Ī constructor that has no parameter is known as the default constructor. ("Student Name: " + student1.name +" and Student Id: " + student1.id) Student student1 = new Student ("Ashok", 101) This would invoke the parameterized constructor. with the values of passed arguments while constructor would initialize data members Example to Understand Parameterized Constructor in Java: package Demo If we want to initialize fields of the class with our own values, then use a parameterized constructor. Access modifiers can be used in constructor declaration to control its access i.e which other class can call the constructor.īasically, there are three types of constructors in java:Ĭonstructors with parameters that can be used to initialize the internal state (fields) of the newly created object are known as Parameterized Constructors. ![]()
