1. As far as possible not to record redundant fingerprints, as far as possible to the touch ID entered the fingerprint to minimize With a more intuitive thinking, the more fingerprints, every time you type, the system needs to match all the records, will inevitably make the unlock speed slightly decreased. In other words, if you have only one fingerprint record, each time you type, the system only needs to make a very simple "one" judgment.

Thread management is usually used more often, but the lock operation and atomic operation is basically useless, but before the university ran a few examples to play. When you see Reentrantlock, it's very simple to find usage and synchronized, but the internal principle is more complicated. On

Next let's take a look at reentrantlock. unlock: Try to subtract 1 from the lock count of the current lock, that is, the State value, and lock adds 1 to the lock count each time. This is why the lock and unlock must appear in pairs, otherwise, the lock count cannot be restored to 0, and other threads cannot try to obtain the lock. Reentrantlock. Unlock () Code
