Today, a client from Poland said that an APP was running normally in English, but when the system language was switched to polish, the program crashed. Well, I am here to maintain it again.
Okay, first switch the s

Recently, the younger brother wrote a hexadecimal conversion to decimal Java program, the general idea of this algorithm is to convert the number of hexadecimal input to 2, and then convert 2 to decimal algorithm. The time efficiency of the algorithm is not very good, you predecessors have any good suggestions hope tha
