Generation of 8-bit non-repeating random codes using timestamps

Generation of 8-bit non-repeating random codes using timestampsmore 0Timestamp Java 16 binary random Code

The timestamp is the total number of seconds from January 1, 1970 (00:00:00 GMT) to the current time. Because time is not duplicated, it is convenient to use time to generate a string of distinct IDs or strings.

Idea: Get the timestamp of the current time , and then convert to 16 binary.

The

resulting results are as follows:

Current time: Mon May 14:47:51 CST 2013
Generate 8-bit random code: 9ca52f20
