While browsing in the programing section I saw books with Javascript, and Java 2 in the titles. What's the difference ? All I know is that they are mainly used in web pages.

I'm slow,but not accurate.
Javascript and Java are two completely different languages. Java is a full fledged programming language, that while it's use a lot on the web, was orginally developed to be a fully cross-platform capable language. It's actually a full fledged progrmming language that gets used for quite a large number of things, but because the general public's primary exposure to it is on the web, that's what it is associated with. Javascript, on the other hand, is a scripting language developed by Netscape specifically for web apps. It primarily is used for visual enhancements, such as graphics that "light up" when you scroll over them, and so on.

Java 2 is what Sun considers there newest version of the language (though the SDK I believe is called Java 1.3.something or other). It is basically just enhancements on Java itself. Sketch was completely on the ball with the differences between Javascript and Java.
To add something... you can use Java to built web applets as well as applications.

Yea, I wasn't too clear on that. In the real world, it's actually used as much for stand alone apps as it is for web pages, if not more.Quote:

Javascript is nothing but a branch of Java meant usually for the Internet programming like HTML but with a SHYT LOAD MORE features then HTML.
Java is the original Java 1.0, 1.1, 1.2 while Java 2 is nothing more then version 1.3 and future versions.
Javascript is not a branch of Java
Javascript is not an enhanced version of HTML, it's used WITH html
And I believe Java 2 refers to JDK 1.2 and later(1.3.0 right now).

I didn't mean it as branch my bad it was kinda hard to explain since I don't have the programmer terms and such and how to say it.
It's cool. I have a hard time at work understanding all the diferent java technologies. J2EE, EJB, etc... https://www.sharkyforums.com/images/.../2005/06/6.gifQuote:

Yeah thanx alot man I am new at this programming and Java...I have a IDG Java 2 Bible and tryed going off my head but I was alittle wrong. https://www.sharkyforums.com/images/.../2005/06/5.gif
Your right also it is or can be confusing...I am 40+pages into the 1,000+page book and am getting confused on what Java 2 is and can do. All the little diff versions of java and stuff.

Just keep reading and you will eventually get it. https://www.sharkyforums.com/images/.../2005/06/5.gifQuote:

Thanks man...BTW what can Java do like what *BIG* things can you make? Games?
You could, but the low efficiency of Java makes it of limited usefulness for things like games. Java is great for anything that needs to be cross platform compatible, but for which speed is a secondary concern.Quote:

This semester I have an operating systems course that uses java program in a unix environment. Our first program is writing a shell with java. But I thought unix and windows were both written in C.
Unix was definitly written in C. What I hear is that C and C++ were the languages behind most of Windows. I am not sure why you would want to write a shell in Java over C but professors often have there own hidden reasons for things. All I know is I took a class that required the writting of a shell kind of like KSH (minus a few features:P) but it was required to be in C.Quote:

Truth is I guess it doens't much matter though wouldn't you have to be running the JavaVM in order to run your Java shell?

The systems actually have both unix(using tshell)and solaris on them. So now I have to start working with java and pico editor but I guess I should be happy since in another class I have to use lex and yacc(then prolog,lisp,and ada).Quote:

Lex and Yacc.... I used Lex and Yacc when I did the shell. If I can promise anything it is that I will NEVER use either lex or yacc for anything again https://www.sharkyforums.com/images/.../2005/06/5.gif

Lex, Yacc: My favorite https://www.sharkyforums.com/images/.../2005/06/5.gif

Any ideas where to get some info on using the two? I would by a book but I only need it for part of the class.Quote:

"A Compact Guide to Yacc & Lex":
http://epaperpress.com/y_man.html
bison and flex are yacc and lex semi-clones:
http://www.gnu.org/manual/manual.html
there are probably more docs floating around various other fsf/gnu sites as well.
Good luck (and my condolences :)

Thanks for the sites. I can't wait until we are done with lex and yacc but then we move onto Prolog.Quote:
