There are three different installation bundles of NetBeans (which can be downloaded from the NetBeans site) that are relevant to Java developers:
Java SE
Java EE
All
In addition to these three bundles, C/C++ and HTML5 & PHP bundles are also available for download. These bundles are not targeted at Java developers though, so they will not be discussed further in this book.
The Java SE bundle provides the standard NetBeans Platform SDK along with support for Java SE and Java FX developers.
The Java EE bundle contains everything that the SE bundle includes, but adds support for Java EE and HTML5 developers. GlassFish Server Open Source Edition 4.1 and Apache Tomcat 8.0.15 are also included with the Java EE bundle.
The All bundle contains everything that the EE bundle includes, but adds support for C/C++, Groovy, and PHP developers.
