You are the bytecode into it receives "numerical string of hexadecimal representation", save in the string variable again?


Now that you are behind the "processing" and needs to be converted to the "value", you might as well put the received data directly in the byte array,
Behind to handle still far more convenient, also far than you use string turn to turn to run far more efficient!

convert hexadecimal MSC controls to receive data stored in a character's, needs to take an examination of the original data are byte value convert hexadecimal characters form after joining together the hexadecimal string, so how to parse need the original data of actual data types, integers, floating point Numbers to have specific code realization, such as
But need to consider receive bytes of high and low order to transform,
