The table below lists packages that are comprised in each profile.NetBeans ) is an open-source Integrated Development Environment (IDE). Each profile specifies a particular set of Java API packages and contains all of the APIs in profiles smaller than itself: compact1 is a subset of compact2, which is a subset of compact3, which in its turn is a subset of the full JRE. Three profiles that have been defined so far are named compact1, compact2, and compact3.
