oop - In Java serialisation why does J signify a long and L signify an Object? -

when serialise object in java, letter j used signify next bytes represent long , letter l used signify object next, why? why not utilize o object , l long?

these letters choosen because of conflicts. guesswork of conflicts:

c taken char. so, used l class.

l taken class. so, used j long.

b taken byte. so, used z boolean.

by way, 'l' doesn't mean 'object', 'fully-qualified-class'.
