It consists of a wide variety of general purpose API’s (like java.lang, java.util) as well as many special purpose APIs
J2SE is mainly used to create applications for Desktop environment.
It consist all the basics of Java the language, variables, primitive data types, Arrays, Streams, Strings Java Database Connectivity(JDBC) and much more. This is the standard, from which all other editions came out, according to the needs of the time.
