With recent developments and new releases, Java is witnessing an exploding change. To help shape its altering state, new collaborative projects are in motion. They aim to improve Java’s ongoing performances and add robust features.
Below, we’ve rounded up three major Java projects. They would be determining the future of this cutting-edge programming language.
In a sole aim to handle concurrency, Java initiated Project Loom to accentuate the system’s ability to switch between fulfilling different sets of instructions. Before this, the Java developers were caught between a rock and a hard place; while handling concurrent tasks, they faced a dilemma between two imperfect options. On one side, they can choose to write a “simple synchronous blocking code” that fails to scale through huge numbers of concurrent tasks or simply pick a complex asynchronous code that can scale but is fairly difficult to write and debug.
Thanks to Project Loom, they can now split the tasks into different threads, including a new lightweight user thread known as fiber. “With fibers, if we can indeed make them much more lightweight than the threads provided by the kernel, we solve the problem. You can have as many of these user-mode lightweight threads as you like and blocking becomes essentially free,” says Ron Pressler, the technical lead for Project Loom at Oracle.
The main objective of Project Amber is to accelerate the speed at which Java adds new features and it seems to be a perfect inclusion since Java 9. Post-Java 9, the speed with which new versions of Java are being rolled out is simply incredible. Below, we have listed down some JDK Enhancement Proposals; however, they are still in progress but falls under Project Amber tag:
- Raw String Literals
- Java Compiler Intrinsics for JDK APIs
- Pattern Matching
- Switch Expressions
Maybe, later, we will do an elaborate blog post on the entire Project Amber.
To enhance the development of advanced JVM and specific language features, Project Valhalla is the key. Below, we have mentioned two candidate proposals and they are:
Good news, a proposal has been made to let JVM handle a new type known as Value Types and it states the goal being to “provide JVM infrastructure for working with immutable and reference-free objects, in support of efficient by-value computation with non-primitive types”.
The proposal even expands the including types that can be employed with generics. For more, watch this space.
