What Is Default Constructors? |
|
Answer» When you CREATE your classes, you should always provide one or more CONSTRUCTOR methods. However, if you do not specify constructor, Java will provide a default constructor for you. Java's default constructor will ALLOCATE MEMORY to hold the object and will then initialize all instance variables to their DEFAULTS. Java will not provide a default constructor, however, if your class specifies one or more constructor for the class.
