[@kumararun8337]

one possible solution to activate the profile based on env is that usually the spring boot apps are run with java -jar command, so we can configure the deployment script in such a way that based on the env for example the dev deployment script should run the command -Dspring.profiles.active=dev java -jar app.jar and similarly the qa deployment script should call the command -Dspring.profiles.active=qa java -jar app.jar. This way based on the deployment env the corresponding application properties would be picked up

[@CodeDecode]

True !!👍👍

[@aabhasjain96]

Other solution is by setting the SPRING_PROFILES_ACTIVE environment variable in your production server's configuration: export SPRING_PROFILES_ACTIVE=prod correct me if I am wrong.

[@croydon21H]

@38:33 no offence but looks like people in India live and die in design patterns. I hardly use strategy pattern or observer etc, provided we use frameworks. After using streams there is significant reduction in boiler plate code, so very little scope to apply explicit design patterns ( as they are already inside framework for use)

Firstly in java 8 Metaspace came instead of PermGen. The biggest disadvantage of PermGen is that it contains a limited size which leads to an OutOfMemoryError. Due to the above problems, PermGen has been completely removed in Java 8. In the place of PermGen, a new feature called Meta Space has been introduced. MetaSpace grows automatically by default

[@CodeDecode]

👍👍

[@jambukumarr9627]

Metaspace is a new memory space. It has replaced the older PermGen memory space right?

[@CodeDecode]

Right

[@sumanlamichhane369]

11:50 use of super keyword in interface??? can someone explain more about this please.

[@sivabalarasup7556]

From Java 8, Funtional interface was introduced, so we can add Static and defaults methods with definition inside the interface rather than just abstract methods. Also, we can achieve multiple inheritance by implementing multiple interfaces, right. So, For eg.. we have the same methods in 2 interfaces like having eat() methods. , then how do we call them to differentiate. For that, we are using Interface.super.eat(). Interfaces are unique right.. So It solves the diamond problem.

[@rohangowda2001]

Inside the method implementation we call the interface implementation which we want to use like Interface.super.methordName()

[@shivambansal494]

PermGen in older versions, replaced by Metaspace in newer versions

[@CodeDecode]

👍👍

[@RupeshGupta-ny5qc]

Why we use wrapper classes.. one of the reason is our Generic type. Generic type arguments are constrained to extend Object , meaning that they are not compatible with primitive instantiations unless boxing is used, undermining performance. And most of the time we seen in collection extensive used Generics for type safety.

In choreography how we will handle parallel call using completable future

[@koustavghosh7627]

The diamond problem occurs in programming languages that support multiple inheritance, where a class inherits from two classes that have a common ancestor. This can lead to ambiguity in the inheritance hierarchy.
