Before doing a test, repeatedly executed several times, found the result is the same:1. Single-threaded synchronized is the most efficient (at the time it felt its efficiency should be the worst);2. Atomicinteger efficiency is the most unstable, different concurrency performance is not the same: short time low concurrency, efficiency is higher than synchronized, sometimes even higher than longadder, but high concurrency, performance is not as good as synchronized, The performance is very unstabl
