Java doesn't seem too popular here but used right it can work pretty well, imo.

For instance, I use Java for the backend of a name generator web app. It's astonishingly fast and displays results almost instantaneously despite running a good amount of backend calculations.

This speed became an issue because you'd push the go button and the names would update - but it seemed like nothing happened. So I ended up adding an artificial delay twice (the first time it wasn't enough of a delay).

On the other hand, its structure and methods can at times be frustratingly complex.
