what are these void,extend,static,public,private

[Abilash ov]

Today i found a app that compiling j2me files in mobile.
From this site mumey.wen.ru

Thats why i started learning j2me today.
I cant to find meanings of these words.

'Void' is the main problem.i saw this in c++.

What is usage of these words

void,extend,static,public,private

Void is actually an English word, and it is really used in that sense: in Java, C, C++ and many other languages it is mandatory to define a return type for your methods/functions. However there are many cases where it has no real meaning, there is no result to return. Then you write 'void'. In C/C++ it has other uses (storing/passing/returning a pointer of unspecified/any type), but this is the Java board here.
Otherwise read some books. It is funny that you are asking questions here for a quarter year without knowing the language(s).
http://books.google.com may be a good starting point, and you can also search for xy tutorial with Google, where xy could be a language.

What you're asking is "please teach me Java and Object Oriented programming", and that's significantly beyond the scope of a forum. I could lecture you eight hours a day for a week just answering the question you've asked. And you'll have a dozen more questions the same.

When I was your age, we had no internet tutorials. We used "books". Since you need to know Java 2 (not Java 7), you might find an old, second-hand book about Java you can use.

I would start with the Java Tutorial because it is free and answers many things. Furthermore, it is for starters, cross-comers and experienced guys. And it is free. If you are more into books, it is available as book as well. Yes, it deals with J2SE 7 and not Java 1.1, we are using in J2ME MIDP – anyway it is a good and quite complete tutorial to learn Java.

Trust me, it is apparent from your question that there are other important things you don't know. We are reluctant to answer you, because we would be encouraging you to use this method of learning the smallest possible amount of knowledge you need to solve each problem, rather than engaging in a process of self-directed learning of the complete subject. Learning of the complete subject is necessary to give you the full set of tools for problem solving. OK, I will indulge you on this occasion, but if you require more information about the Java language, if you have problems that stem from not understanding the language basics correctly, or if you don't understand my answer because you're not understanding the concepts I'm describing, I will repeat my advice for you to get a book on Java.

extends: is a subclass of
public: (of class-member) is accessible within all other classes, (of a class) is accessible to classes in other packages
private: is accessible only within this class
class: begin the definition of a class
void: method does not return any value
return: return a value from this method (exiting the method, unless it is within a "try" or "catch" block that contains a corresponding "finally" clause, in which case finally clauses are executed first)
