If you add at least one other constructor to the body of the CM圜lass class (for example, a constructor with one parameter), then the default constructor will not automatically be generated classCM圜lass
#Java default constructor code#
The above code means that you can declare a class object using the default constructor: // It works because the class does not implement any constructors In the next class declaration, the default constructor is generated automatically class CM圜lass If the class contains an implementation of at least one constructor with parameters, then to declare the default constructor, it must be explicitly specified in the class.įor example. That is, the default constructor is automatically generated in the class only if the class does not contain implementations of other constructors. If the class does not declare any constructor, then the default constructor will be generated. In some cases, the default constructor is generated in the class automatically? Example In the most general case, for the ClassName class, the default constructor is as follows: classClassName
