Theres two main feature sets Id like to mention here: Before Java 8, whenever you wanted to instantiate, for example, a new Runnable, you had to write an anonymous inner class, like so: With lambdas, the same code looks like this: You also got method references, repeating annotations, default methods for interfaces, and a few other language features. To note fairly, when coupled together with Just-In-Time compilers, Java provides high A Computer Science portal for geeks. In 17.5 we addressed this issue, making these cast-like functions never produce function calls in generated code, even in debug mode. You can find a complete feature listhere, but essentially, you are getting Unicode 12.1 support, as well as two new or improved preview features (subject to change in the future): Switch expressions can now return a value. ). Over 2 million developers have joined DZone. ZGC is designed to have pause times that do not scale with the heap size, and we clearly see that this is the case when the heap is enlarged to 128 GB. However, instead of declaring possible values, you declare the fields. Java 17 LTS is going to be supported for years to come. the Machine Reassignment numbers (B1 and B10) fluctuate a lot between runs on the same JDK and GC.
