             Summary: Convenience methods needed for RandomStringGenerator
                 Key: TEXT-96
                 URL: https://issues.apache.org/jira/browse/TEXT-96
             Project: Commons Text
          Issue Type: Improvement
    Affects Versions: 1.1
            Reporter: Peter Phillips
            Priority: Minor


{{RandomStringGenerator}} is extremely verbose compared to the deprecated commons.lang3 {{RandomStringUtils}}.

Previously we could write:
{code:java}
RandomStringUtils.randomNumeric(10)
{code}
to generate a numeric string whereas this now has become:
{code:java}
new RandomStringGenerator.Builder().withinRange('0', '9').build().generate(10)
{code}
although in practice we would then also use static imports too.
The {{randomAlphabetic}} conversion is even more verbose:
{code:java}
new RandomStringGenerator.Builder().withinRange('A', 'z').filteredBy(new CharacterPredicate() {
                    @Override
                    public boolean test(int codePoint) {
                        return codePoint >= 'a' || codePoint <= 'Z';
                    }
                }).build().generate(10))
{code} and at that point I lost enthusiam with trying to replicate {{randomAlphanumeric}}.

I don't think the average java developer would understand what a code point is in the first place so then trying to get our automation testers to use the new API to implement random alphanumeric character generation would be difficult.

I therefore suggest that commons-text should have a copy of {{RandomStringUtils}} which can even delegate to {{RandomStringGenerator}} or alternatively convenience static methods for the common use cases.
