public int	nextCommon(int n, boolean confirmPositive) Method copied from the jdk src 1.4.2_03. param n the seed for the next random number param confirmPositive boolean flag that is set to true when the random number to be returned has to be a positive integer return the random number exception IllegalArgumentException if seed is less than zero if (n <= 0) throw new IllegalArgumentException("n must be positive"); if ((n & -n) == n) // i.e. n is a power of 2 return (int)((n * (long)next(31)) >> 31); int bits, val; boolean condition; do { bits = next(31); val = bits%n; condition = (bits - val + (n - 1) < 0); if (confirmPositive) { condition = (condition&&(val > 0)); } } while (condition); return val;
public int	nextInt(int n) Returns a random integer. param n the seed for the next random number return the random number exception IllegalArgumentException if seed is less than zero return nextCommon(n, false);
public int	nextPositiveInt(int n) Returns a positive random integer. param n the seed for the next random number return the random number exception IllegalArgumentException if seed is less than zero return nextCommon(n, true);
