As a computer science student, we all had a java programming language course on our one semester and we learnt it from bottom to top but not all. Chances are that we coded java for the semester end project and never really looked backed at it like making a executable file of it. As it is also not on the course syllabus people don?t tend to give it a try. So I?m here to tell my experience in making a windows executable file with a straightforward simple guide.

  1. Making a jar executable file
  2. Making a executable file

Before you go through this guide, you must already have initialized JDK and JRE path and installed Eclipse with a sample project with it.

Making a jar executable file

A JAR (Java ARchive) is a package file format typically used to aggregate many Java class files and associated metadata and resources (text, images, etc.) into one file for distribution.

  1. Open the eclipse with the java project.

Making a executable file

EXE is a file extension for an executable file format. An executable is a file that contains a program ? that is, a particular kind of file that is capable of being executed or run as a program in the computer. To make a executable file, we will need a separate tool for it called Launch4j. The download link for this software is down below.

http://launch4j.sourceforge.net/

Launch the software after installing it and follow the following guidelines.

  1. Add you own path for the Output file (Where you want to save it). Then add the path of the jar file that you just made on the Jar section. Optionally you can also add a icon for you executable file, just point the path of the .ico file on the Icon section.

2. Now head over to the JRE tab and add you Minimum Jre version on the Min JRE Version. As of March 4, i am adding 1.7.0 as my minimum Jre version. After that click on build (Gear icon).

3. Finally, you will have your executable file with your own icon (if added).
