The Long class wraps a value of the primitive type <code>long</code> in an object. An object of type <code>Long</code> contains a single field whose type is <code>long</code>. <p> In addition, this class provides several methods for converting a <code>long</code> to a <code>String</code> and a <code>String</code> to a <code>long</code>, as well as other constants and methods useful when dealing with a <code>long</code>.
