Part 5removing repetitive code is related to overloading. The number and type of the parameters can affect the number and type of the class's constructors. It is not possible to have two constructors with the exact same parameters.
You can see in the above program that we called the parameterized constructor during object creation. When overloading a constructor, it's important to note that the java compiler inserts the default constructor into our code if we don't implement any constructor at all. You can see the example below.
Can constructor be inherited?
It's practically not possible to get inheritance. One might call other constructors in a construction. Only fields, methods, and nested classes are included in the definition of a class. fields, methods, and nested classes are all members of a subclass.
The constructor of the superclass can be invoked from the subclass, because they are not members.
In case of inheritance, every class would have a no argument constructor. That doesn't break the principles. The conclusion was that the constructs are not inherited on the language level due to the principles of the OO.

Can we override the constructor?
The programmer can change the default constructor in the class. Let's take a look at the language. The name of the constructor should match the class name, and it should not have any parameters.
The class in which it is declared is where a constructor belongs. A sub class is different from a class that is the same. Affirmatives simply can't be interfered with. The default constructor is a no-arg one.
The solution is that what you describe is not over. The compiler will create a default constructor if you do not specify a default constructor. If it's a subclass, it's going to call.
Can we overload constructor in Python?
In this class, we talk about the concept of method overloading and constructor overloading in other languages as well.
If you take an example in python, you will understand how method overloading and constructor overloading works. In the above program, there is an overload of the constructor. The last defined constructor is considered by python.

Can we make constructor final?
It is not possible to change the value of the variable through the program, therefore Constructor cannot be final.
This is the final method of the class example, SubClass.java:10: error: display in Sub Class cannot override display in Super Class final public void display.
