LOGIC OF==ALPABETIC===ALPHANUMERIC===NUMERIC===NEGATIVENO===checking in TALEND

**AlphaNumeric||length > 5|| ==0 then reject else Accept

b=myString.matches("[0-9]+") ? myString.length() > 5 || myString.matches("0") ? "false" : "true" : "false";

**AlphaNumeric
myString.matches("[A-Za-z0-9]+")

**Numeric
myString.matches("[0-9]+"))

**Negative
myString.matches("-[0-9]+"))

**Alphabetic
myString.matches("[A-Za-z]+")
