Returns a pseudorandom, uniformly distributed int value between 0 (inclusive) and the specified value (exclusive), drawn from this random number generator's sequence.

Usage

From source file:Main.java

public static double nextDouble(int lower, int upper) {
    Random ra = new Random();
    int n = lower + ra.nextInt(upper - lower);
    double m = ra.nextDouble();
    return n + m;
}

From source file:Main.java

}

From source file:Main.java

    Long currentTimeMillis = System.currentTimeMillis();
    return Long.parseLong(currentTimeMillis.toString() + s.toString());
}
