Multiple inheritance The case that a class takes multiple direct base classes is called multiple inheritance, and a base class is single inheritance. A member function with the same name may appear in two base classes In a derived class, you must dissolve the ambiguity of the member functions of the two base classes, and the best way to do this is to redefine the function with the same name in the derived class. In this way, the derived class will localize t

joins the UDP header before the data and then gives the data to the ip_build_xmit () function, which constructs the IP header based on the destination IP and port information provided by the socket, and then calls the Output_ Maybe_reroute () function processing. The Out_maybe_reroute () function checks whether the packet needs to be routed, and finally the ip_output () function is written to the send queue, which is processed by the ip_finish_output () function after the write is completed.The

Reason One In a class/interface of inheritance (extends)/implementation (implements), other jars on which this class/interface depends cannot be relied upon or referenced in this class. Example: Class A Inheritance (extends) class B, import the Com.jixue.dna.ui.portal.TaskUtil class in Class B, and Class A is not dependent on the Com.jixue.dna.ui.portal.jar package, so error. Reason Two In a class/interface, the dependent jar package relies on another jar package, and the class/
