Default Constructor

What is the signature of the default constructor? Specifically, what access specifier does it use?
My understanding is that it uses the same access specifiers the class's access specifiers.
Am I right?

The following excerpts from Section# 8.6.7 of the Java Language Specification explains us about the signature of the default constructor:
If a class contains no constructor declarations, then a default constructor that takes no parameters is automatically provided:
1.If the class being declared is the primordial class Object, then the default constructor has an empty body.
2. Otherwise, the default constructor takes no parameters and simply invokes the superclass constructor with no arguments.
3. If the class is declared public, then the default constructor is implicitly given the access modifier public (�6.6); otherwise, the default constructor has the default access implied by no access modifier.
Hope this answers your query.
