2。看看desc信息便知道vlue和random这两个函数的区别了,value返回的是number类型,并且返回的值介于1和0之间,而random返回的是BINARY_INTEGER类型 5)生成随机日期 Oracle将日期作为过去某个关键日期(如果你好奇的话,我可以告诉你这个日期是公元前4712年1月1日)的整数偏移量来保存。这就意味着你可以通过寻找与你希望的...

The random number obtained by one thread is not affected by the other thread, whereasjava.util.Randomprovides random numbers globally. Also, unlikeRandom,ThreadLocalRandomdoesn’t support setting the seed explicitly. Instead, it overrides thesetSeed(long seed)method inherited fromRandomto always throw...
BetterRandom provides several pseudorandom number generators that are intended as drop-in replacements forjava.util.Random. Features common to all PRNGs inbetterrandom.prng Reproducible: ThegetSeed()function retrieves a seed that can be passed into the constructor to create another PRNG giving the sa...
