In Java, constructors cannot be overridden in the same way that methods can be overridden. Overriding a method means providing a different implementation of the method in a subclass, while maintaining the same method signature (name, return type, and parameters). However, constructors do not have a return type and are not inherited by subclasses.
Instead, when you create a subclass, you can invoke the constructor of the superclass using the
super keyword and provide additional functionality specific to the subclass. This is achieved through constructor chaining. By default, if you don’t explicitly define a constructor in a subclass, the compiler will automatically insert a default constructor that invokes the default constructor of the superclass using
However, if you want to provide different constructors in the subclass, you can define them with a different signature and call a specific constructor of the superclass using
super(). This allows you to initialize the inherited members of the subclass using the constructor of the superclass.
java training in coimbatore will help students to understand the object-oriented programming in a better way. They will get an understanding of how to write a program using Java. The course also includes a session on how to debug programs written in Java.
In this example, the
Superclass and provides an additional constructor with a different signature. The
super(value) statement in the
Subclass constructor invokes the constructor of the
Superclass and passes the
value parameter to initialize the inherited members of the subclass.
So, while you cannot override constructors in the same way as methods, you can utilize constructor chaining and call the constructor of the superclass to provide different constructors with additional functionality in subclasses.
