Default access modifier for a Java constructor

Question

Can anybody explain what the default access modifier is for an explicit no-arg constructor (and other constructors)?

Answer 1

JLS 8.8.9 Default Constructor

If a class contains no constructor declarations, then a default constructor that takes no parameters is automatically provided:

if the class is declared public, then the default constructor is implicitly given the access modifier public;
if the class is declared protected, then the default constructor is implicitly given the access modifier protected;
if the class is declared private, then the default constructor is implicitly given the access modifier private; otherwise,
the default constructor has the default access implied by no access modifier.
