Which of the following is incorrect?
a. A constructor may be static.
b. A constructor may be private.
c. A constructor may invoke a static method.
d. A constructor may invoke an overloaded constructor.
e. A constructor invokes its superclass no-arg constructor by default if a constructor does not invoke an overloaded constructor or its superclass’s constructor.
a A constructor cannot be static, because you use a constructor to create a specific instance. A constructor may be private. In this case, the use cannot create an instance using this constructor.

A constructor can invoke an overloaded constructor using the this keyword. So, the correct answer is A.
