There are over 7.6 million Java developers worldwide. Meaning Java is one of most of the preferred language in the World. If you’re interested in understanding or learning Java, you’re in the right place.
First, Oracle updates the language regularly incorporating more advanced features. There are five new Java features you need to know about as you wait for the launch of Java 11. For additional Java tutorials and examples for beginners and professionals, you can visit https://javatutorial.net/.
1. Local Variable Type Interface
Despite the awesomeness of the feature, it has limitations, and it can only work with local variables. Still, Java remains less dynamic compared to python, where users can change variables after assigning values.
Pro users view the feature as a significant advancement in Java, and it will save users loads of time, especially when dealing with complex codes.
2. Half-Year Updates and Releases
Java will now introduce newer updates every six months in the new time-based release versioning. The latest release model has stirred conversations among programmers and users. The main arguing point revolves around the practicability of the updates. Many users feel the period is too short, and new updates could come before users are conversant with previous features. Team Oracle considers the move significant because they will do an LTS release every three years.
3. Garbage Collector Interface
The new feature is a real tech advancement. The previous Garbage interface posed many challenges to users. Users could not easily remove or add GC to the Java development kit. The problem made development confusing and time-consuming.
With the new interface, adding GC is super easy, as users follow a set of prescribed interfaces instead of tracking areas in the JVM that need updating.
4. Parallel Full GC for G1 (JEP 307)
New JK10 features focused on enhancing user performance, and by creating a parallel full GC for G1, Oracle hit the nail on the head. Previous JVM featured a default G1 optimized for incremental collection, but it could not reclaim memory quickly. It ended up switching to full GC, which was disruptive and time-consuming.
The Parallel Full GC comes in as the backup to G1, in case disruptions occur in G1, the Parallel GC makes concurrent collections.
5. Root Certificates (JEP 319)
Another advanced and user-friendly update to JK10 is the inclusion of root certificates into the OpenJDK source. Previous JK versions had an empty cacerts file which made it hard to optimize valuable security protocols. Root certificates will allow the developers to counter the problem updating security protocols.
