Java File Editor is a tiny and portable utility that provides a standard text editor for compiling and executing Java code. It is very easy to use, thanks to its overall simplicity.

As installation is not an issue, you can drop the executable file somewhere on the hard disk and click it to run.

It is also possible to save Java File Editor to a USB pen drive or similar storage unit, in order to run it on any machine with minimum effort.

An important aspect to take into account is that the Windows registry is not updated with new keys, and no extra files are automatically created by the utility.

The GUI is represented by a common window with a layout that resembles the one of Windows Notepad, where you can write text in the traditional method, as long as it is Java code, of course.

The project can be saved to JAVA format. You can cut, copy, paste and delete text, format, compile and execute Java code, as well as enter command lines for execution. There are no other notable options available through this tool.

Java File Editor has minimal impact on system performance, running on a very low amount of CPU and RAM. It has a good response time and works well, without causing the operating system to hang, crash or pop up error dialogs.

We have not come across any issues throughout our evaluation. Unfortunately, the app has not been updated for a long time, and it has stability problems on later operating systems.
