Java for test automation | Java 21: Pattern matching in switch de-structuring, virtual threads ⚡

Java 21 allows you to pattern match types within switch statements that work for null and can even have conditions using when. All within a single line. The switch statement is becoming extremely concise and friendly to use

Also, we can destructure a complex nested record within an instanceof clause in if and easily access values without having to work with long cast statements

Lastly, we wrap up this one by an example of how you can use lightweight virtual threads to do parallel tasks in your automation. Pretty sleek if you ask me.

Hope you’ll make use of these in your automation and supercharge your java code while being extremely readable.
