How to Compile and Run Java within Notepad++

When you are learning a programming language such as Java it is always recommended not to make use of IDEs like Eclipse or IntelliJ as when you type code without the help of real-time compilation error highlighting and intellisense, you make a lot of error, but that's how you learn the syntax of the language quickly.

So you can make use of editors like Notepad++ in such cases, as they will syntax highlight your code.

If you want to compile and execute your Java code within Notepad++ then you should make use of the Java Plugin.

Plugin to Compilation and Execution Java Code directly from Notepad++
