8.8. Constructor Declarations

A constructor is used in the creation of an object that is an instance of a class (§12.5, §15.9).

ConstructorDeclaration:      ConstructorModifiers_opt ConstructorDeclarator                              Throws_opt ConstructorBodyConstructorDeclarator:      TypeParameters_opt SimpleTypeName ( FormalParameterList_opt )

The SimpleTypeName in the ConstructorDeclarator must be the simple name of the class that contains the constructor declaration; otherwise a compile-time error occurs.

In all other respects, the constructor declaration looks just like a method declaration that has no result type.

Constructor declarations are not members. They are never inherited and therefore are not subject to hiding or overriding.
