Here we useRFCOMM is a simple serial linear simulation protocol that provides RS232 control and status signals. That is, a serial port (COM) transmission protocol with a baud rate of BITs and 8 bits. Therefore, mobile phone Bluetooth can

What are the writereplace () and readresolve () Methods used? These methods are used to allow an object to provide an alternative representation for itself withinObjectstream. Consider for instance the common means of implementing an enumerated type:

Problem: All developers know that constant classes are the most common way to define data dictionaries. However, with the development time of the project and the change of the development team, there will often be a particularly hard-pressed
