Parameterized Constructor in Java Parameterized constructors are constructors that take parameters. Use a parameterized constructor if you wish to provide your own values as the default values for the class’s fields. Default Constructor in Java When the program is executed, the Java compiler automati...
A parameterized constructor has one or more parameters. We can use a parameterized constructor in case we need to pass some initial values to the member variable of the class. import java.io.*; class DemoClass { // data members of the class. String name; int id; // parameterized construc...
However, as classes become more complicated and the initialization of instances becomes more nuanced, developers should provide a customized set of parameterized constructors to their users.Cameron McKenzie has been a Java EE software engineer for 20 years. His current specialties include Agile ...
