3. Generate Random double Math.random()or Random classnextDoublemethod to generate random double number in java. We can generate random bytes and place them into a user-supplied byte array using Random class. The number of random bytes produced is equal to the length of the byte array. Rando...

源码分析:当第一次调用Math.random()方法时,会生成伪随机数生成器randomNumberGenerator,之后再调用此方法将不再生成伪随机数生成器,而是继续沿用此伪随机数生成器。此种生成随机数的方式是线程安全的,但是在多线程下可能性能比较低。 java.util.Random工具类 基本算法:linear congruential pseudorandom number generator...
Returns the next pseudorandom, uniformly distributed long value from this random number generator's sequence. void setSeed(long seed) Sets the seed of this random number generator using a single long seed. Methods declared in class java.lang.Object clone, equals, finalize, getClass, hashCode, ...

2.5.java.security.SecureRandom If we have security-sensitive applications, we should consider usingSecureRandom.This is a cryptographically strong generator. Default-constructed instances don’t use cryptographically random seeds. So, we should either: ...
