The parameterized constructors are the constructors having a specific number of arguments to be passed. The parameter list of a constructor looks like this: dataType parameterName. A constructor of the class has same name as class name. The constructor for Car will initialize the three variables of the object. The parameter list contains either primitive data type such as integer, float or double or non-primitive type. when we want to initialize the data members by passing some arguments, we use parameterized constructor. Constructors are used to initialize objects. In this video, I have taught you, Parameterized Constructors.Parameterized Constructors are the same as the Member functions of a structure/class but with di. Parameterized constructor: If the constructor of the class accepts arguments into its parameter list then the constructor is said to be parameterized constructor.

If we want to initialize fields of the class. What are parameterized constructor in Java A constructor that has parameters is known as parameterized constructor.

Learn: What is parameterized constructor in c#, how it is declared, defined and what parameterized constructor does?Īs we have discussed that default constructors are used to initialize data members of the class with the default values, and the default constructors do not require any arguments that’s why they called zero or no arguments constructor.īut, if we want to initialize the data members of the class while creating the object by passing values at run time i.e. With this in mind, a parameterized constructor method is used for setting properties of the object to certain value, while the default won't set any value to any of the properties.
