            Java8 Understanding tail-recursive function using a lambda expression:
            Asked 2021-Jun-15 at 08:49

            I am trying to lambda Java8 lambda expressions, Wherein I came across this example. I am unable to understand the program flow,

            The the below example when the factorialTailRec(1, 5).invoke() statement is called the program flow is as shown below:

            1. The program first goes to the factorialTailRec method and once and checks if the number value is equal to 1. In the first iteration, it's not so it goes to the else part.

            2. In the else block the flow is redirected towards the call method inside the TailCall class which will return the same object.

            3. Now the invoke method is called and then the Stream object tries to iterate through the result. I am not getting how the factorialTailRec is called again? They say its because of the below statement,

            It's worth reading the introduction to JUnit 5. You are making a common mistake in thinking that JUnit 5 is a monolith. Rather:

            https://junit.org/junit5/docs/current/user-guide/#overview-what-is-junit-5

            Unlike previous versions of JUnit, JUnit 5 is composed of several different modules from three different sub-projects.

            JUnit 5 = JUnit Platform + JUnit Jupiter + JUnit Vintage

            Like JUnit Jupiter, Cucumber is a test engine using the JUnit Platform. Extensions are a concept from JUnit Jupiter and don't carry over to Cucumber.

            Without a single example I could find in the cucumber documentation.

            You'll not find anything in the main documentation until the JUnit 5 integration is feature complete. Until that time it is perfectly possible to use Cucumbers JUnit 4 integration with JUnit Vintage.

            However if you're more experimentally minded you can use the documentation with the source code:

            https://github.com/cucumber/cucumber-jvm/tree/main/junit-platform-engine

            @CucumberOptions - there is an interface CucmberOptions which I can implement and return all required properties, but this feels like a step back from the parameterized annotation.

            The Cucumber JUnit Platform integration defaults to scanning for glue and features on the class path root. If you follow the conventional maven/gradle/java project layout no additional configuration is needed.

            So step definitions go in src/test/java/com/example and features in src/test/resources/com/example.

            If you have a more complicated setup you should either wait and use JUnit4/Junit Vintage or simplify your setup.

            Java 11 implementation has not introduced thread-safe implementation of java.util.HashMap.

            In the JDK documentation, it is clearly stated that access to Hashmap is NOT synchronized, so the behavior in a multithreaded application is unpredictable, and deadlock situation is indeed a possible side effect.

            In addition, it is also said that if you want to have synchronized access, you MUST provide synchronization policy by using static method Collections.synchronizedMap, this is the piece of code to realize that:

            There are two problems in your code:

            1. You haven't used Locale with DateTimeFormatter which is a Locale-sensitive type. Never use SimpleDateFormat or DateTimeFormatter without a Locale.
            2. You have used H instead of h for 12-hour format. The symbol, H is used for 24-hour format.
