JDK 21: New Features

The Java Platform—developed by Oracle—includes two components: Java Standard Edition (Java SE) and the Java Development Kit (JDK). Java SE is a computing platform that is used to create software applications by developing and deploying portable code for environments such as desktops and servers. Java SE includes different application programming interfaces (APIs) and the Java Class Library. Examples of packages included in Java SE are java.io, java.math, java.util, etc., and it includes APIs such as Applet, AWT, Collections, Swing, JDBC, etc. You can find more about Java SE and its editions at [1].
