* Many applications will find the method {@link Math#random} simpler to use. |
| 52 |
|

| 53 |
+ |
* <p>Instances of {@code java.util.Random} are threadsafe. |
| 54 |
+ |
* However, the concurrent use of the same {@code java.util.Random} |
| 55 |
+ |
* instance across threads may encounter contention and consequent |
| 56 |
+ |
* poor performance. Consider instead using |
| 57 |
+ |
* {@link java.util.concurrent.ThreadLocalRandom} in multithreaded |
| 58 |
+ |
* designs. |

* <p>Instances of {@code java.util.Random} are not cryptographically |
| 61 |
+ |
* secure. Consider instead using {@link java.security.SecureRandom} to |
| 62 |
+ |
* get a cryptographically secure pseudo-random number generator for use |
| 63 |
+ |
* by security-sensitive applications. |
