Question

I wrote this code in JAVA but I don't want to change it from regex to use a loop. Not sure if I should use charAt or not.
Kindly help with what the code will look like if it is not regex:

protected boolean isTextValueValid(String value){
String regex = "\\b\\d\\{3, 8}";
Pattern p = Pattern.compile(regex);
if(value==null || !value.matches(regex)){

return false
}

Matcher m = p.matcher(value);
return m.matches();
}

I would appreciate like two options that will use either enhanced Loop or ForLoop
