Method Detail

getNextInt

public int getNextInt()

Description copied from interface: RandomGenerator

Returns the next pseudorandom, uniformly distributed int value from this random number generator's sequence. The general contract of nextInt is that one int value is pseudorandomly generated and returned. All 2³² possible int values are produced with (approximately) equal probability.

Specified by:

getNextInt in interface RandomGenerator

Returns:

the next pseudorandom, uniformly distributed int value from this random number generator's sequence.

getNextInt

public int getNextInt(int n)

Returns an integer drawn uniformly from 0 to n-1. Suffice it to say, n must be > 0, or an IllegalArgumentException is raised.

Specified by:

getNextInt in interface RandomGenerator

Parameters:

n - an integer value

Pre:

n > 0

Returns:

an integer value

Throws:

java.lang.IllegalArgumentException - if n =< 0

Post:

the returned value x is : 0 =< x =< n-1
