“Knock, knock.”

“Who’s there?”

very long pause….

“Java.”

At least it's a way to have multi-platform stuff.

Knock knock...

Who's swift there?

Have you ever seen Python? In the Python documentation, you can see that even Java is faster than Python(for like 3 times).

Java was only slow the fist few years.

Startup time isn't very fast, yes.

I dont like java as its too verbose. But you definitely cannot complain about its speed. Unless you are a proficient c/cpp coder and are actually at rhe stage of optimisation, jit compiler could outperform an average c code base.
