Amey Jadiye commented on TEXT-97:
---------------------------------

In that case we have {{.selectFrom()}} API, All I'm expecting is to have 
different API available in different situations, I understand that  only 
{{.selectFrom()}} is enough but others provide more flexibility to existing API.

Few and selected characters : {{.selectFrom(char ... chars)}} // like "I need 
just few special chars"

Single range : {{.withinRange(int min , int max)}}  //like "I want only numeric"

Multiple ranges : {{.withinRange(final char[] ... pairs)}} //like "I want 
alphanumeric" 

> RandomStringGenerator should be able to pass multiple ranges to .withinRange()

> Users should have ability to pass multiple ranges to generate desired output.
> Ex. For
> *.randomNumeric()*
> {code}
> char [][]  ranges = {{'0','9'}};
> RandomStringGenerator generator = new 
> RandomStringGenerator.Builder().withinRange(ranges).build();
> {code}
> *.randomAlphabetic()*
> {code}
> char [][]  ranges = {{'A','Z'}}; // or {{'A','Z'},{'a','z'}}
> RandomStringGenerator generator = new 
> RandomStringGenerator.Builder().withinRange(ranges).build();
> {code}
> *.randomAlphanumeric()*
> {code}
> char [][]  ranges = {{'0','9'},{'A','Z'},{'a','b'}};
> RandomStringGenerator generator = new 
> RandomStringGenerator.Builder().withinRange(ranges).build();
> {code}
