This section describes some of the enhancements in Java SE 16 and JDK 16.
The full version string for this update release is 16.0.2+7 (where "+" means "build"). Why would you need the JDK then? Because the application server will convert JSP into Java servlets and needs to use the JDK to compile the servlets.
For example, if you are deploying a web application with JSP, you are technically just running Java programs inside the application server. Sometimes, even if you are not planning to do any Java development on a computer, you still need the JDK installed. The new license permits certain uses, such as personal use and development use, at no cost - but other uses authorized under prior Oracle JDK licenses may no longer be available. The new Oracle Technology Network License Agreement for Oracle Java SE is substantially different from prior Oracle JDK licenses. It is capable of creating and compiling programs. It has everything the JRE has, but also the compiler (javac) and tools (like javadoc and jdb).
Mozilla (Java section - obsolete, install one of the plugin packages from the table above).The JDK is the Java Development Kit, the full-featured SDK for Java. JavaFAQ - in this wiki, only one question so far TODO(wiki consolidation): maybe everything should be moved from here to Java/RequestedPackages?

Instead of managing each alternative separately, you can update them all in one go with 'update-java-alternatives' from java-commonĭevelopers - Java packaging work in Debian Most java-related executables, multiple of which can be installed at any time, are managed by the 'alternatives' system. java1-runtime-headless, java2-runtime-headless, java5-runtime-headless, java6-runtime-headless.
These cover runtime compatibility and come in two flavours headless (omits graphical interfaces) and normal. There are several virtual packages used in Debian for Java. Understanding Java Virtual packages names Remember to manually check for updates and generate and install the updated pacakges! WARNING: there is no way to get automatic security updates. Debian, however, provides an helper to generate Debian packages from upstream tarballs. No longer available in Debian due to license reasons.
