yield in Kotlin Coroutines In Kotlin Coroutines, the yield() function is a suspending function provided by the Kotlin Coroutines library. It is used to cooperatively give up control of the current coroutine, allowing other coroutines or tasks to run. This is useful in scenarios where you want to ensure fairness in execution or avoid blocking a thread for too long. In the example, doWork () is a suspend function that prints a message and then calls yield(). This allows other coroutines (in this case, jobB) to run in between the iterations of jobA. Without yield(), the jobA would run to completion before the jobB even started. Follow Outcome School for knowledge-packed content. Keep Learning, Keep Sharing, and Keep Growing.

Interview Question: Object Level Lock vs Class Level Lock in Java Answer: Object Level Lock: • Locks on the instance level. • Each instance has its own lock. Class Level Lock: • Locks on the class level. • Only one lock exists for the entire class. If there are 100 instances of a class, then only one thread will be able to execute the synchronized block in any one of the instances at a time, and all other instances will be locked for other threads.

Interview Question: Shallow vs. Deep Copy in Java Answer: When we create a copy of an object in Java, we have two options: shallow copy and deep copy. Shallow Copy • Creates a new object but only copies the references to the fields present in that object. • Reference fields (objects, arrays) are copied as references. This means that changes to the referenced objects affect both the original and the copied objects since both point to the same memory location. • Note: Primitive fields (int, boolean, etc) are copied directly. Deep Copy • Creates a new object and recursively copies all nested objects, creating independent copies of them. So, all fields, including references, are duplicated. • The copied and original objects do not share the same references, so the changes in one do not affect the other.

Kotlin Interview Question: What happens if an exception is thrown inside an async coroutine, but await() is never called? Answer: Unlike launch, which throws exceptions right away, async holds exceptions in its Deferred result. If you don’t call await(), the exception will go unnoticed. • async returns a Deferred, which captures the exception and only throws it when you call await(). • If await() is never called, the exception sits silently in the Deferred and is effectively ignored. val deferred = async { throw RuntimeException("Something went wrong") } // No await() here, so the exception is never seen. #Kotlin #AndroidDev
