In C ++, constructor is a special function called when the component object is called. Its purpose is to initialize the object, so that the object can be in a reasonable State before it is used. However, the design of constructor functions is not

Question one: Can Java constructors be inherited?The author of Java read a book said: "Java subclasses naturally inherit its superclass" non-private members.Normally Java constructors are set to public (if you do not write the constructor, Java
