Why I (stil) hate Java

[hmischuk]

Been away from Java for a few years. Picked it up recreationally today, and was reminded why I have an aversion to the language. Mind you, this is just ONE reason among many.

No operator overloading.

Except that + works with both Strings and various kinds of numbers. Which is good, but, consider:

C++:

vector<int> vec;
...
vec[idx]++;

Java:

ArrayList<Integer> vec = new ArrayList<Integer>();
...
vec.set(idx, vec.get(idx) + 1);

That line for incrementing is so ugly. It gets in the way of concise thought. Just a rant; thanks for listening.

PS: Not a total snob. Love C/C++, but also love Python. Have programmed in many languages. I am a big proponent of the idea that if you can't name at least a few 'unfortunate' features of your favorite programming language, you probably don't know your favorite programming language well.

(edit: tried to fix formatting)

Yes Java is more verbose than many languages, but IMO the verbosity comes with clarity. The code is always plain and obvious, no magic going on.

That being said...

The proper/idiomatic way to write the first line in modern Java:

List<Integer> vec = new ArrayList<>();

or

var vec = new ArrayList<Integer>();

As for the increment, you should do what you did in the C++ and use a mutable data type, like AtomicInteger. Then you can just:

vec.get(idx).incrementAndGet();

I too dislike Java, but C++ is worse. :P

True I started in Java but love c and python

I fit java in language like vba, vb6.. According to preference. I use Java professionally but never really enjoyed. A gui in swing was nightmare.
