Random. The
 semantics differ in that the underlying browser's implementation is used. The
 random generator cannot be seeded or otherwise used to reproduce a particular
 sequence of results.| Modifier and Type | Method and Description | 
|---|---|
| static boolean | nextBoolean()Returns true or false with roughly equal probability. | 
| static double | nextDouble()Returns a random  doublebetween 0 (inclusive) and 1
 (exclusive). | 
| static int | nextInt()Returns a random  intbetween -2147483648 and 2147483647
 (inclusive) with roughly equal probability of returning any particularintin this range. | 
| static int | nextInt(int upperBound)Returns a random  intbetween 0 (inclusive) andupperBound(exclusive) with roughly equal probability of
 returning any particularintin this range. | 
public static boolean nextBoolean()
public static double nextDouble()
double between 0 (inclusive) and 1

 (inclusive) with roughly equal probability of returning any particular
 int in this range. The underlying browser's random
 implementation is used.public static int nextInt(int upperBound)
