J2ME in a Nutshell

Name

Byte

Synopsis

Byte provides an object wrapper for a Java byte primitive value. The constructor initializes the wrapper with a byte value, after which the object becomes immutable. The value associated with a Byte object can be retrieved using the byteValue() method.

The static parseByte() converts a numeric value held in a string into a primitive byte. 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 static variables Byte.MIN_VALUE and Byte.MAX_VALUE are byte (not Byte) values that represent the smallest and largest values, respectively, that can be held in a byte primitive.

Note that this class is derived from Object and not Number, as the CLDC does not provide a Number class as the J2SE does.
