J2ME in a Nutshell

Name

Long

Synopsis

Long provides an object wrapper for a Java long primitive. The constructor initializes the wrapper with a long value, after which the object is immutable. The value associated with a Long object can be retrieved using the longValue() method.

The static parseLong() converts a numeric value held in a String into a primitive long. The single-argument variant of this method assumes that the String is encoded in base 10; the two-argument variant can be used to specify a different number base if necessary. A NumberFormatException is thrown if the String does not represent a valid number in the given number base.

The zero-argument toString() method returns a String representation of the value of the Long encoded as a base 10 number. There is also a static variant of this method that prints the value of a given long as a base 10 number, as well as a two-argument variant that prints a value using digits from the number base supplied as its second argument.

The static variables Long.MIN_VALUE and Long.MAX_VALUE are long (not Long) values representing the smallest and largest values, respectively, that can be held in a long primitive.

Note that this class is derived from Object and not Number, as it is in the J2SE. This is because the CLDC does not provide the Number class.
