If possible, rewrite the code so that the Random object is created once and saved, and each time a new random number is required invoke a method on the existing Random object to obtain it.If it is important that the generated Random numbers not be guessable, you not create a new Random for each random number; the values are too easily guessable.If all clone() methods call super.clone(), then they are guaranteed to use Object.clone(), which always returns an object of the correct type.This class defines a clone() method but the class doesn't implement Cloneable. Using bit arithmetic and then comparing with the greater than operator can lead to unexpected results (of course depending on the value of SWT. = 0' instead of ' Class implements Cloneable but does not define or use the clone method.
This produces mediocre quality random numbers and is inefficient.
You should strongly consider using a java.security.
This non-final class defines a clone() method that does not call super.clone().
If this class ("A") is extended by a subclass ("B"), and the subclass B calls super.clone(), then it is likely that B's clone() method will return an object of type A, which violates the standard contract for clone().
As of Java 1.6, both Identity Hash Map and Enum Map did so.
When iterating through such a Map, the Entry value is only valid until you advance to the next iteration.
