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.

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

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

Solution 3

I found this online java compiler and runner. It works in realtime and also with threads. Amazing ! http://www.browxy.com

Solution 4

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.

This one is good for ruby.
