Non-case Scala classes also supported, but they should have getter accessors for all arguments of a primary constructor Types that supported as map keys are primitives, boxed primitives, enums, String, BigInt, BigDecimal, java.util.UUID, java.time.*, literal types, and value classes for any...

Environment entry names are the names used by a component for a JNDI lookup of some customizable parameters. T his name also apperas as the value of the env-entry-name element within the env-entry element in the deployment decriptor of the component. ...
Ifnotgood at remembering bitwise operations, then conventional subtracting of ascii value should alsodothe job. We often need to return empty Set, List or Map when input is invalid. To make code more readable: returnCollections.EMPTY_SET;returnCollections.EMPTY_LIST;returnCollections.EMPTY_MAP; ...
Initialization code refers to the code that is responsible for configuring the processor and memory, initializing devices, and performing administrative tasks before the operating system can run. It plays a crucial role in transitioning the system from the reset state to a state where the operating ...
