What Is Difference Between Constructor And Method In Java?

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

Constructor needs to have the same name as that of the class whereas functions need not be the same.

    * There is no return type given in a constructor signature (header). The value is this object itself so there is no need to indicate a return value.
    * There is no return statement in the body of the constructor.
    * The first line of a constructor must either be a call on another constructor in the same class (using this), or a call on the superclass constructor (using super). If the first line is neither of these, the compiler automatically inserts a call to the parameterless super class constructor.
