Answer / biswajit rout

Constructor is a special type of member function which
never returns any value.It is mainlly used for
initilazation of data member(s).It can only invoked by the
creation of the object of the respective class.constructor
can very well use AccessSpecifier.
constructor can very well overloaded but it can not be
overridden.

Answer / dipankar gain

constructor is just like a method(a function in C/C++) which
is called before the object of the class is created.
Generally you dont need to give the constructor in the class
definition but if you want to do something like initializing
variables, starting a connection, connect to the database,
then you should use the constructors.
If you dont include the constructor in your class, then the
java compiler puts it for you, its called the default
constructor.
