Threading problems
When working with concurrency, we have the opportunity to increase performance! However, with great power comes great responsibility; things can go awfully wrong as well. Therefore, we must be aware of several potential problems that can arise due to incorrect or inefficient synchronization. Let’s discuss four common threading problems: data races, race conditions, deadlocks, livelocks, and starvation.
Data races
We have just talked quite a bit about data races already. They occur when two or more threads access shared data concurrently, and at least one of them modifies the data, leading to unpredictable results. Here’s an example of an innocent-looking snippet of code that can lead to a data race in multithreaded environments:
class Counter { private int count = 0;
public void increment() {
count++;
}
