Some programs allow the conversion of Java programs from one version of the Java platform to an older one (for example Java 5.0 backported to 1.4) (see Java backporting tools). Regarding Oracle Java SE Support Roadmap, [ 4 ] version 23 is the latest one, and versions 21, 17, 11 and 8 are the currently supported long-term support (LTS) versions ...
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile.

Following their promise to release a Java Development Kit (JDK) based almost completely on free and open-source code in the first half of 2007, [11] Sun released the complete source code of the Java Class Library under the GPL on May 8, 2007, except for some limited parts that had been licensed to Sun by third parties and Sun was unable to re-license under the GPL.

Java and C++ use different means to divide code into multiple source files. Java uses a package system that dictates the file name and path for all program definitions. Its compiler imports the executable class files. C++ uses a header file source code inclusion system to share declarations between source files.
Java is explicit about extending classes and implementing interfaces, while C# infers this from the kind of types a new class/ interface derives from. C# supports more features than Java, which to some extent is also evident in the syntax that specifies more keywords and more grammar rules than Java.
The Java software platform provides a number of features designed for improving the security of Java applications. This includes enforcing runtime constraints through the use of the Java Virtual Machine (JVM), a security manager that sandboxes untrusted code from the rest of the operating system, and a suite of security APIs that Java developers can utilise.
