in comment you write about Integer, Long types but you use int, long - it is not the same types.
for repeat() is better to use StringBuilder.
btw there is "-".repeat(20) in Java 11

The randomOfAny method works only with non primitive data types. Long works
long don't works. And so on...
If you mean any other please write Details. Thanks.
Please take a look at my version of 'manualy' string sort.

I know only POJO object, it is term usually used in java EE
Plain Old Java Object (POJO)
. is an ordinary Java object (class)
what is not POJO
. if bound by special restriction
.. if follow of the major Java object models, conventions, or frameworks
. if requiring class path
.. if extend prespecified classes, interfaces, annotations
.. if need complicated object frameworks
what is still POJO:
if it accepts these requests:
. is serializable,
. has a no-argument constructor
. uses getter and setter methods, equals(), hashCode()
. follow a simple naming convention of get/set methods.

I mean these places:
Long -> long
* PARAMETER a Long type number.
public static boolean isPrime(long number){
--
* PARMETER an Long value.
public static ArrayList<Long> pfz(long number){
--
Integer -> int
* PARMETER 2 or more Integers or an Array of Integers
* RETURN the GCD as an Integer
public static int gcd(int... n){
int a ..
return a;
