I'm not getting that green color button along with my code. how to do that? i'm just doing code changes in existing code and need to test it

Thanks for your question! Since I haven’t seen your exact code or project setup, this is an educated guess based on common issues. Here are a few things to check: *1.JUnit Library* Make sure the JUnit library is added to your project's pom.xml. It's essential for writing and running tests. Refresh your project after adding JUnit so IntelliJ detects it. *2.Location of Test Files* Your test files should be in a special test folder, like src/test/java. Right-click the test folder in IntelliJ and mark it as "Test Sources Root" if it isn't already. *3.Test Methods* Ensure your test methods have the @Test annotation. Without it, IntelliJ won’t recognize the methods as tests. *4.Fix Errors* Make sure your code has no compilation errors. Errors in your test or main code can prevent IntelliJ from showing the green run button. *5.IntelliJ Configuration* Go to File > Project Structure > Modules and ensure JUnit is listed as a dependency. If IntelliJ is acting up, try clearing the cache: File > Invalidate Caches / Restart > Invalidate and Restart. *6.Alternate way* *Auto-generate Tests:* IntelliJ can create basic tests for you. Right-click the class you want to test, then go to Generate > Test. *Run Without Green Button:* You can right-click the test class or method in the editor and select Run.

In my mac at JDK option it is showing "temurin-17 Eclipse Temurin 17.0.12" Can I continue with it or should I install JDK ?

I think you can continue with "temurin-17 Eclipse Temurin 17.0.12" .Temurin is a fully compatible, open-source build of the OpenJDK. It's essentially the same as the Oracle JDK, just with a different name and distribution.But keep in mind in that case you are using Java 17 .
