What is a Constructor, Constructor Overloading in Java and Copy-Constructor ?

Answer

A constructor gets invoked when a new object is created. Every class has a constructor In case the programmer does not provide a constructor for a class, the Java compiler (Javac) creates a default constructor for that class.
The constructor overloading is similar to method overloading in Java. Different constructors can be created for a single class. Each constructor must have its own unique parameter list.
Finally, Java does support copy constructors like C++, but the difference lies in the fact that Java doesn’t create a default copy constructor if you don’t write your own.
