A DESCRIPTION OF THE REQUEST :
The only way to check if a numeric String has a valid format is to try to parse it an catch the exception thrown. I'm requesting an easy way to make sure that a String has a valid numeric format.

JUSTIFICATION :
Writing this kind of code to perform a basic task, to find out the validity of a number, is not acceptable.

boolean isNumeric = true; try{Integer.parseInt(fieldValue);}catch(Exception e){isNumeric = false;}

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
boolean isNumeric = Integer.isInt(s);

boolean isNumeric = Integer.isInt(s,radix);

Similar methods should be implemented in the Byte, Short, Integer, Long, Float and Double classes.
