Notepad++ Compile and Run Java Programs

Notepad++ is a great file editor. It has many features. The most important feature which I like about Notepad++ is its light weight. It loads up so quickly, that's great. It also provides syntax highlighting for many languages. I use notepad++ to edit general files as well as my simple Java programs.
Although notepad++ provides functionality to run external programs, I prefer NppJavaTools plugin to compile and run Java programs using notepad++.
You can download NppJavaTools plugin from this page - NppJavaTools.


Installation of plugins in notepad++ is very simple process. All you have to do is copy plugin dll into plugins folder of notepad++ installation directory and restart the notepad++.

This plugin provides following features,

  1. Compile and run your Java files within Notepad++
  2. Set custom hotkeys for compiling and running Java Code
  3. Library support

Compile and Run

This function allows you to run your Java programs to compile and run from Notepad++.

Set Custom hotkeys

This function allows you to set custom hotkeys for Compile and Run command.NppJavaTools Settings

Library support

You can specify which libraries to use while compiling and running your Java programs using NppJavaTools. As shown in above image of Settings window, you can add, remove single or clear all the library files.


  1. Site unaviable, link dont work.

  2. Sure, Notepad++ is a great tool for java code editing, but definitely not the best one. As for me, such editors as Atom or Sublime Text has a way more customizing features in addition to their simplicity. Moreover, I ended up with notepad right after the moment when it suddenly crush all file associations on my laptop, so I couldn't open my codes anywhere. Glad that I found solution quickly here, it fixed all associations and allows me to open my java files as well as open txt file Don't know any exact alternative for npp, but I highly recommend you to switch to another editor

Spring AOP : JDK Proxy vs CGLib Proxy

Spring framework is one of the most widely used framework in Enterprise application development. It has so many features such as Dependency injection, Data access integration, MVC, AOP which takes care of most of the boilerplate part of project, and developers can then focus on business logic only.

One of the important feature in Spring is AOP. It is used by almost every enterprise application which is being developed using Spring.

AOP So what is AOP? Definition of AOP -
Aspect oriented programming is a programming paradigm which aims to increase modularity by allowing the separation of cross cutting concerns. Well, my understanding of AOP is - AOP allows us to introduce/join new modules in your project at pre-specified dynamic locations without having to code for it. Traditional examples of AOP is Transaction management, logging etc. You can read more about AOP at here.

This article is for those who know AOP, have used AOP in their projects but do not know how Spring or other DI fra…

Java Tools Plugin for Notepad++

This post and the plugin is outdated. Please use plugin from this link which is updated and allows customization of shortcut key mappings and much more.
Notepad++ is a great free editor. I like notepad++ because its a light weight editor and loads instantly. I use notepad++ for editing many files everyday. One plugin I always wanted was a plugin which lets me compile my java files and execute them from editor itself, but I couldn't find it so I wrote a myself. This plugin can be downloaded from this link.
I am working on this plugin to make it more effective, so that if user have more than one installations of JDK or JRE then user should be able to choose which one to use etc.
This is a simple plugin which has two commands-
Compile - compiles a java file.
Run - executes a java file.
For using this plugin Java must be installed on the system.
