isNumeric

public static boolean isNumeric(java.lang.Object value)

Useful for figuring out if an Object is a number.

isNumeric

public static boolean isNumeric(java.lang.String str)

Checks if the String contains only unicode digits. A decimal point is a digit and returns true.

null will return false. An empty String ("") will return true.

Parameters:

str - the String to check, may be null

Returns:

true if only contains digits, and is non-null
