Local records and Sealed classes find their way in Java 15
Keeping up with the six-month cycle tradition, after the release of Java 14 on March 17, 2020, we now have Java 15, the next non-LTS version rolling out on September 15, 2020.
Here’s a quick look at features that are a part of Java 15:
instanceof(Second Preview) — JEP 375
/Library/Java/JavaVirtualMachinesas shown below:
$ cd /Library/Java/JavaVirtualMachines $ sudo cp ~/Downloads/openjdk-15_osx-x64_bin.tar.gz /Library/Java/JavaVirtualMachines $ sudo tar xzf openjdk-15_osx-x64_bin.tar.gz $ sudo rm openjdk-15_osx-x64_bin.tar.gz
Once that’s done, open the
bash_profile using any text editor. I'm using
vim ~/.bash_profile. Set the path of Java15 to JAVA_HOME, save changes and do a
source ~/.bash_profile to reflect the changes.
Finally, you’re ready to compile and run programs using Java 15. We’ll be using JShell, an interactive REPL command-line tool for quickly testing the new Java 15 features.
It’s important to note that many features released in Java 15 are in preview. This means that though they’re fully working right now, things may be modified in the future. Some could be made a standard or simply removed in the next release cycles. In order to test preview features, you need to explicitly set
--enable-preview when running the JShell or Java Program as shown below:
jshell --enable-preview javac --release 15 --enable-preview Author.java
In the next few sections, let’s discuss the significant language changes in Java 15.
