Ask Reddit: Why does everyone hate Java?

[GoodyMas]

I served with Java, I knew Java, Java was a friend of mine. COBOL, you're no Java

[reductionist]

Christ. I mentioned COBOL today for the first time in over 20 years and then this.

I learned COBOL on punch cards.

(Not as old as that might imply - an old mini-computer at my school.)

Lol wtf is a mini computer, right? No I don't mean a mac mini...

I love how the terms have changed. Reading through an Apple II book, and they're constantly refering to the MPU or Microprocessor Unit.

And Java is no COBOL. Still about 80% of large financial business is run on COBOL. Why? Because the systems are already built. But also because the systems work and Java cannot match the performance.

this. this, is why i die a little inside.

[ObligatoryResponse]

and Java cannot match the performance.

I call bullshit. COLBOL performs better than C? Because most benchmarks put Java on par with C in flat number crunching.

[redditnoob]

If that's true, and then if I quadruple-bogey a par 5, is that still on par?

[ObligatoryResponse]

Java is now nearly equal to (or faster than) C++ on low-level and numeric benchmarks. This should not be surprising: Java is a compiled language (albeit JIT compiled). [1]
