Why does the JDK have both Math.random () and the Random class?

Question

Is it just because of the "big API syndrome" or the generation of random numbers that are more prone to preferences in some situations? If that were the case ... I would have thought it was important to control bias.

Answer 1

In fact, everything is the same. Just a convenient method. Check out javadoc here . Alternatively, you can Math.random() creating random objects, and Math.random() will use a static random instance.
