Online compilers/runtime for Java, C++, Python and ObjC?

Question

Does anyone know of a good online compiler/runtime (for C++, Java, Python, ObjC etc.) that I can access on the web?

What I'm looking for is something that would allow me to type in a program in a web form and to run the program and see the results online.

(Let's not get into the why for now. Suffice it to say for the moment that I don't always have access to a compiler/runtime, and firing up an IDE is just overkill for testing out some code snippets)

I know of codepad.org -- but I'm looking for something better.

Answer 1

This works for java: http://www.zamples.com/JspExplorer/index.jsp

Answer 2

CodeIDE is an ok one: http://www.codeide.com/

Answer 3

For C++, you could try CodeControl, Comeau or the one from code.vcer.net.

Answer 4

http://codepad.org/

codepad.org is an online compiler/interpreter, and a simple collaboration tool. Paste your code below, and codepad will run it and give you a short URL you can use to share it in chat or email.

Languages:

C
C++
D
Haskell
Lua
OCaml
PHP
Perl
Plain Text
Python
Ruby
Scheme
Tcl

Answer 5

You can practice your SQL here.

Answer 6

This one is good for ruby.

Answer 7

Here is an open source one: http://codenode.org, which supports Python and Sage well, but also aims to support other languages like Ruby, R, etc. Probably the best description of Codenode is "Google docs combined with Mathematica Notebooks".

Answer 8

i have an java online compiler http://youjavait.com/java-online-compiler.html

Answer 9

ideone is something better but what particular advence do you need?

Answer 10

Right now, you can use http://sagenb.org. This is a free open source online Google Docs-like programming notebook environment, which I provide (thanks to a generous grant from the National Science Foundation). Once you create an account and create a new worksheet, click on the box (fourth from left) labeled "Sage" and change it to Python. Now all the code you type in is evaluated using Python. The main drawback is that there are well over 30,000 users of this resource, so sometimes it is slow.
