Java makes a distinction between these two, which is often ignored.
A no-argument constructor is simply a constructor which takes no arguments.
The default constructor is a special kind of no-argument constructor. If no constructor whatsoever is provided by the programmer, then the system will always provide a default constructor, whose behavior is defined by this spec.
So, strictly speaking, a programmer can never write a default constructor (but they can certainly write a no-argument constructor).

The above might be amended for this case: a no-arg constructor can have an implementation which simply mimics the behavior of the default constructor.

Should "system" be replaced by the Java compiler since it's the compiler that will automatically insert a default constructor into the class file?
