On your machine you have installed the required SDKs and tools, but now you have your Java programming codes on a USB stick and no access to your home computer or laptop.
So how do you compile and run the Java code?
You can always start afresh on the new computer. Google and download the SDK, JDK and probably also download your favorite editor off the Internet. For the first-time users, who are usually school and college students, installing IDE like Eclipse will require some assistance and time.
Even a regular developer will require some amount of time to setup the installation. But there’s a better way out of this mess. Probably the quickest way to run and compile your codes without installing SDK or downloading an IDE application is to use Compilr.
Compilr is an online integrated development environment supporting PHP, C++, Ruby, Java, C# and Visual Basic among several other programming languages.
Register Your Free Compilr Account
Before you begin compiling programs on Compilr, you need to create an account. Once you are done registering an account, which should not take more than a few minutes, you are free to use this tool!
iDeone is yet another similar tool to compile and run code online in no time. This online compiler and debugging tool allows anyone — without having to register an account — to run the code in more than 40 programming languages.
The tool does have its set of limitation. You cannot import a project or execute all the files together. On the brighter side, students who are learning programming concepts & languages will find this tool really useful.
