Constructors are special methods of the class due to their role in object creation process. Syntactically too they are different. Following are the facts that summarize how they are different from the other methods of a class:
The constructor declaration is very similar to a method
declaration, but its name must be exactly same as the class’s name.
The constructor declaration does not have return type (not
even void).
None of the non-access modifiers is applicable to
constructor declaration. The constructor is not inherited [l7] from the superclass. Therefore,
the modifiers such as final or abstract do
not make sense to it. The modifier static is also not applicable
to a constructor. Constructor is invoked to create an object and is associated
with an object therefore it cannot be static.
