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

原文 2011-12-20 00:20:39 8 1 random/ java

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.

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.

Why use Math.random(), and what it does

How does the distribution of Math.random()*50 + Math.random()*20 compare to Math.random()*70?

Why does math.random(999999999999) returns 1 in Lua?

Is it possible for Math.random() === Math.random()

Does math.random assume 0 to be an integer?

When does Math.random() start repeating?

What algorithm does Math.random use?
