While this may be fine for one developer working on a project, teams or even an individual who has been away from a piece of code for a while can lose track of the usages of a value, and could unintentionally introduce a bug here. However, most of the time, its probably not important enough to sacrifice code readability. How do I launch a completely independent process from a Java program? } Put simply, batch processing is the process by which a computer completes batches of jobs, often simultaneously, in non-stop, sequential order. Object-oriented practices, particularly in Java, call for the use of whats known as the builder pattern when creating objects that have a number of different fields. This seems like a fairly common call pattern and I would expect there to be a library or much simpler design pattern to accomplish this, but I haven't been able to find anything. Remember, readability is key, and mental time spent filtering out redundant types is time not spent interpreting the meaning of a line of code. Disabled by default.
