Which of the following statements is incorrect in reference to Java?

Q: Answer-Which of the following statements is incorrect in reference to Java?

Declaring a constructor with void makes it a method, not a constructor. If no constructor is defined, Java provides a no-argument default constructor that initialises fields to default values 0 for numbers, null for objects, false for boolean. Once any constructor is defined, the default constructor is not automatically provided.

A A constructor has the same name as the class; a method can have any name

B A constructor has no return type (not even void); a method must have a return type (or void)

C A constructor is called automatically when an object is created; a method is called explicitly

D A constructor can be declared with a 'void' return type to indicate it returns nothing

E A constructor can be overloaded (multiple constructors with different parameters); methods can also be overloaded
