Create a 16 digit random number generator in Java
Problem:
Create a 16 digit random number generator in Java
Solution:
This can be easily achieved by using ThreadLocalRandom by declaring the bounds equal to the smallest and largest 16 digit numbers.
private static void random() {
/* return a random long of 16 length */
long smallest = 1000_0000_0000_0000L;
long biggest = 9999_9999_9999_9999L;
// return a long between smallest and biggest (+1 to include biggest as well with the upper bound)
long random = ThreadLocalRandom.current().nextLong(smallest, biggest+1);
System.out.println(random);
}
