Is it just because of "large API syndrome" or generating random numbers that are more biased favored in some situations? If it was..I would think that controlling the bias-ness would be important.

random() method returns a pseudorandom double type number greater than or equal to 0.0 and less than 1.0. . When this method is first called, it creates a single new pseudorandom-number generator, exactly as if by the expression new java. util. Random.
random() is based on java. util. Random , which is based on a linear congruential generator. That means its randomness is not perfect, but good enough for most tasks, and it sounds like it should be sufficient for your task.
The Java Random class is a part of the java. util package and contains inbuilt methods to generate random numbers.
random() method. This method returns a pseudorandom positive double value between 0.0 and 1.0, where 0.0 is inclusive and 1.0 is exclusive. It means Math. random() always return a number greater than or equal to 0.0 and less than 1.0.
They're the same, really. Just a convenience method. Check the javadoc here. Additionally, you're able to re-seed by creating random objects, while Math.random() will use a static Random instance.
