The future for Java is bright!

If you are coding in the JVM but the system you are working on was created using Java 11 or even 8 ๐Ÿšจ, and want to try out the new features of Java like:

  • Local Variable Type Inference
  • Local Variable Type in Lambda Expressions
  • Switch Expressions
  • Text Blocks
  • Pattern Matching of instanceof
  • Records
  • Sealed Classes

Maybe it’s time to use SDKMAN, it allows you to switch from different Java versions in an easy way.

Install SDK

curl -s "" | bash
source "$HOME/.sdkman/bin/"

Installing a specific version of Java

Then you can list all the available versions of Java

SDK will download and unzip the specified version of Java into a directory on your computer. Additionally, it will update the environment variables. Easy peasy

sdk install java 19-amzn

Ready to use โญ๏ธ

java -version

Switching Java Versions

You can check the current installations with:

ls -l ~/.sdkman/candidates/java

Happy Coding. Its time to try the new Java features while you still contributing to your legacy Application ๐Ÿš€

Then you should be able to use the Java version which allows you to work with the new features or legacy ones.

sdk use java <version>
