copy Constructor in java #shorts

In Java, a copy constructor is a special type of constructor that creates an object using another object of the same Java class. It returns a duplicate copy of an existing object of the class.

We can assign a value to the final field but the same cannot be done while using the clone() method. It is used if we want to create a deep copy of an existing object. It is easier to implement in comparison to the clone() method.
Use of Copy Constructor
We can use the copy constructor if we want to:

Create a copy of an object that has multiple fields.
Generate a deep copy of the heavy objects.
Avoid the use of the Object.clone() method.
Advantages of Copy Constructor
If a field declared as final, the copy constructor can change it.
There is no need for typecasting.
Its use is easier if an object has several fields.
Addition of field to the class is easy because of it. We need to change only in the copy constructor.
