The general contract ofnextFloatis that onefloatvalue, chosen (approximately) uniformly from the range0.0f(inclusive) to1.0f(exclusive), is pseudorandomly generated and returned. All 224possiblefloatvalues of the formm x2-24, wheremis a positive integer less than 224, are produced with (approxi...
In simplerandom.iterators, the generators are provided as Python iterators, of infinite length (they never raise StopIteration). They implement the __next__() function to generate the next random integer. All the generators output 32-bit unsigned values, and take one or more 32-bit seed value...

uniform_int_distributionClassProduces a uniform integer value distribution across a range in the closed interval [a, b] (inclusive-inclusive). uniform_real_distributionClassProduces a uniform real (floating-point) value distribution across a range in the half-open interval [a, b) (inclusive-exclusi...
intrandomNumberInRange=(int)(Math.random()*(max-min+1))+min; System.out.println("RandomIntegerinRange:"+randomNumberInRange); } } 以上代码将输出如下结果: RandomFloat:0.5896278763187332 RandomInteger:42 RandomIntegerinRange:7 四、总结 通过JavaRandom类的random()方法,我们可以生成0到1之间的随机浮...
