Constructor will be automatically invoked when an object is
created whereas method has to be called explicitly.

Answer / kabita
constructor & methods are both member functions of a class.
when an object is created the constructor is invoked
automatically,bt we have to call the methods explicitly
through objectname.
methods have returntype ,bt constructors haven't.
constructors must have same name as class name bt methods
have not.
constructors are used for initialization of
objects,variables.

Answer / pranab dutta
A constructor is a member function of a class that is used
to create objects of that class where as a method is an
ordinary member function of a class.
Constructor has the same name as the class itself and
Member has its own name.
A Constructor has no return type, and is invoked using the
new operator.. Whereas a Member has a return type (which
may be void), and is invoked using the dot operator.

mainly there are
i.constructor name is same as the class name whereas method name doesn't.
ii.constructor is implicitly called when an object is created.....but the method is explicitly called by using object.
iii.constructor has no return type hence it doesn't return anything.....but method has return type.
iv.constructor is used to create and initialize data members.....where as method is created to code the specific task.

Answer / devarathnam c,kotagudibanda(po
Hi...
Constructor(): It is also a method but it doesnot allow
return type even void also.It will call automatically
whenever an object is created of a appropriate class.
But class name and constructor should be the same.d
Method():U have to call explicitly .

Answer / teju
constructor: It is one special member function.it has name same like class .it does not have any return type.it gets executed when we create an object of class and invokes implicitly. constructor is used to initialize the variables ,start the thread
method:
it gets executed explicitly when object is created . it has return type .
method is used to invoke the task or block of code
