Method

LongrandLong(long minimum, long maximum)
rand Long 
assert minimum <= maximum;
long value = Math.abs(seed.nextLong()) % (maximum - minimum + 1) + minimum;
assert minimum <= value && value <= maximum;
return value;
longrandLong(long n)
rand Long 
long bits, val;
do {
    bits = (new Random().nextLong() << 1) >>> 1;
    val = bits % n;
} while (bits - val + (n - 1) < 0L);
return val;
longrandom(long begin, long end)
random 
long rd = begin + (long) (Math.random() * (end - begin));
if (rd == begin || rd == end) {
    return random(begin, end);
return rd;
longrandom(long max)
random 
return (long) (Math.random() * max);
longrandom(long min, long max)
Returns a random long number between the value min and the value max. 
if (min > max) {
    throw new ArithmeticException(
            "min" + String.valueOf(min) + "Value min " + min + " must be lesser than value max " + max);
return (long) (Math.random() * (max - min) + min);
longrandom(long range)
Returns a random value in the range [1 - range] 
return (long) ((Math.random() * 100000) % range) + 1;
StringrandomHexOfLong(long max)
random Hex Of Long 
long randomInt = randomLongWithMinMax(0, max);
return Long.toHexString(randomInt);
longrandomLong()
random Long 
x ^= (x << 21);
x ^= (x >>> 35);
x ^= (x << 4);
return Math.abs(x);
longrandomLong()
random Long 
return RND.nextLong();
longrandomLong(long min, long max)
Generates pseudo-random long from specific range. 
return min + (long) (Math.random() * (max - min));
