I don't know much about Python... the import statement has to be the first statement in a class (in Java). Where you can use wildcards and it does only build used classes of the library during compile time.
Do you know what you want to write yet? e.g. Applets and programs work a little different, use different methods to construct objects and have access to different libraries.

| Programming is about not trying to reinvent the wheel. That is why java is viewed as one of the best because it has so much power on the OOP side. As for a other languages there are ones that create more efficient output and there are some that make it easier to create (easier syntax). As an bosses standpoint java is very productive since most of the stuff you can grab from other classes, which where already created and distributed for free, without doing any work. |

Python is an at rumtime interpreted language where the notion of classes, objects, functions and basically everything is build around the concept of key-value (map). the import statement can thus appear anywhere in the code which is basically to say 'now read the definition of class/whatever' because I'm going to use it.
Java is a bytecode compiled language where every class is defined in its own file. When a class is loaded at runtime the classloader needs to know what classes are needed and load those first if needed before loading the actual class. That's just how the language is designed.

I'm beginning to understand... this java limitation ensures that a senior architect can fast see libraries that developers point on the beginning before a class. So he easy can see that developers don't use hacks from some libraries, for example, if the developer doesn't import the java.io.File then he cannot do manipulations with files. Then the Java are good for projects with many developers. Am I right?

Absolutely not. This just ensures that your code is not an ineligible mess. Think of it as of Python forcing you to indent. |

Quite funny but the C++ panel is out of date. Rvalue references and move semantics eliminate unnecessary copies.

The idea was to get zixnub to say something because I had a look at his wm and it's in java but he's disappeared

Already I've understood that the import isn't generally necessary operation in the Java. I had to read more books.
The Java is beautiful language. And I'm happy that I choose it.
Of course, I will be more happy if I've found the job via the Java.
How do you think, what must I learn after the Java Core? Hibernate, Spring or JavaEE? What would be better? |

Boy Im glad that's an individual perspective.
public static void CamelFuckingCase
public int CantFuckingReadWhatImTyping
public void HowManyGodDamnTimesDoIHaveToSayPublic
Individual perspective...
For me this is considered "beautiful":
std::sort(data.begin(), data.end(), predicate)
Either use a predicate function or functor or implement an operator<

Only constants and class names should start with capital letters 
Most python code I have seen, have variables and methods like:
def a(b):
def ab(b,c):
def abc(d,t):
How often do I have to say def here and how do I know what 'a' is or 'abc' etc.?!?

It seems creators of many languages never heard of the term Don't Repeat Yourself.
Dynamic languages are whole another clusterfuck.
How can you write a solid interface when your functions can take anything and everything?( just like a cheap prostitute)

When you visit a friend's house how often do you climb in through the windows, and how often to you enter via a door?

I'm sorry, I was looking at android.
Actually I wasn't but I thought that was a clever thing to say. Instead I was bussy refactoring my wm (current head in master doesn't even build properly) and get the bindings for Xcb automatically generated by swig (swig, not swing). Talking about swig, there is just NO java native autowrapper (except for swig) that can produce sane code (for xcb), let alone code, let alone run without blowing up and crashing. I was also bussy getting a decent jvm running on my raspberry pi.

No, it isn't beautiful. Someday you'll see that. But I'm glad you're happy. :)

It's more difficult than you think to get an entry level java position, but web development positions are abundant. I'd encourage you to learn coffeescript and apply for web dev jobs, playing up your coffeescript experience as javascript experience.
It _probably_ won't rot your brain, which is more than I can say for Java, _and_ there will be more viable job opportunities.

Hi, guys. OP is back.

Yes, you was right. I was learning the Java for 3 months and now I work as a Java developer (the middleware development). Today I've gotten my first salary.
Thank you all for an attention. The Java won in this topic. |
