Concurrency
In the previous chapter, we explored the nuances of streamlined data manipulation and parallelized operations that utilize the power of modern multi-core processors. This was already a little introduction to this chapter’s topic: concurrency!
Concurrency allows applications to perform multiple tasks at the same time. This makes the system more efficient. Any available resources can be utilized more efficiently, and this leads to overall improved performance. In order to do multiple things at the same in Java, we need to know quite a bit.
