356: Enhanced Pseudo-Random Number Generators
This feature provides users with brand new interface types. They bring along pseudorandom number generators. These include PRNG that is jumpable and a whole class of PRNG algorithms.
382: New macOS Rendering Pipeline
This feature enables the implementation of a Java internal rendering Pipeline in 2D specific to macOS. This uses an API named Apple Metal. This serves as an alternative to the already existing pipeline. The already existing pipeline uses an API called Apple OpenGL.
391: macOS/AArch64 Port
This feature enables the porting of JDK to macOS/AArch64
398: Deprecate the Applet API for Removal
This is a measure to go along with all the browsing vendors since the existing browsing vendors have removed any support for the plugins of the Java browser or have announced to do the same in the future.
403: Strongly Encapsulate JDK Internals
This feature encapsulates all internal elements leaving some APIs alone. Due to this, the users will no longer be allowed to ease the strong encapsulation of internal elements.
406: Pattern Matching for the switch (Preview)
This feature helps to enhance Java language with things such as pattern matching that would be specific to switch expressions and statements. This would include extensions to the language.
407: Remove RMI Activation
This feature removes the RMI Activation mechanism. RMI stands for Remote Method Invocation. While removing the RMI activation mechanism, the rest is preserved.
409: Sealed Classes
This feature enhances Java as a language. This feature adds sealed classes and interfaces. They restrict which other classes and interfaces might implement or extend.
410: Remove the Experimental AOT and JIT Compiler
This feature removes the Experimental AOT and JIT Compiler, which stands for ahead-of-time and JIT stands for just-in-time. The compiler in question has been used a lot less than was expected since it was introduced. To avoid the effort that goes into maintaining such a compiler, it’s been removed. However, the developers can continue to use the externally built versions to do the same.
411: Deprecate the Security Manager for Removal
The Security Manager is being deprecated to go under removal in releases of the future. This dates back to Java version 1.0. This Security manager has not been used for many years, and now it is rarely used to secure any server-side code.
412: Foreign Function & Memory API (Incubator)
The main use of this feature is to introduce an API that will be used by Java programs through which one can interoperate between the code and the data outside of Java runtime. With the help of the API, java programs can call the native libraries and work on the data without any danger or brittleness.
414: Vector API (Second Incubator)
This feature hereby introduces another API that helps to express computations in vectors. These computations compile at run-time over optimal vector instructions using supported CPU architectures as platforms. This helps to achieve superior performance to comparable computations in a scalar.
415: Context-Specific Deserialization Filters
This feature allows applications to construct context-specific and selected deserialization filters which would be enabled through a JVM-wide filter factory.
Installation of JDK 17
Let us discuss the steps to install the latest version of JDK.
Step 1: Go to Oracle website.
Step 2: As per your operating system, download the version required for example, in exe for Windows, .debian fo Linux , .dmg for macOS.Then install the file and run in your local machine bu choosing the directory.
Step 3: Set the path for the system environment variable and in order to check whether this new JDK is installed or not, verify via terminal by entering the below commands.
javac --version
java --version
