doubles() – generates a DoubleStream of random numbers.longs() – generates a LongStream of random numbers. Pick a random number code#Random.ints( 7, 0, 1000).forEach(System.out::println) Code language: Java ( java ) Random.ints( 0, 1000).limit( 7).forEach(System.out::println) The following example prints seven random numbers to the console: The Random.ints() method generates an IntStream: a stream of random int values. With the introduction of streams in Java 8, has been extended to include methods for generating random number streams. You can read more about this in the chapter on Pseudorandom Numbers. This is only necessary for special requirements. You can use the setSeed(long seed) method or the second constructor Random(long seed) to set the so-called "seed" value of the random number generator. nextGaussian() – returns a Gaussian-distributed random number with a standard deviation of 1.0, i.e., according to the normal distribution, the probability of a number close to 0 is higher than the probability of a number far from 0.nextBytes(byte bytes) – fills the specified byte array with random bytes.nextDouble() – returns a random double number greater than or equal to 0.0 and less than 1.0 (this method is called from Math.random(), as described in the previous section).nextFloat() – returns a random float number greater than or equal to 0.0 and less than 1.0.
