Reflection: the soul of frame design The first thing to write is *. java The file is generated by the compiler *.class Finally, the bytecode is run through the virtual machine *.class file * Framework: semi-finished software. Software development can be carried out on the basis of the framework to simplify coding * Reflection: encapsulating ...

select multiplexing in channel In the data communication system or computer network system, the bandwidth or capacity of the transmission medium is often greater than the demand for transmitting a single signal. In order to make effective use of the communication line, one channel is expected to transmit multiple signals at the same time ...
