title: Creating My Own Library Of Utilities
body: <p>I have written a program that has a couple of utility classes.  Right now I have the class embedded in my program but I would like to pull it out to a JAR file that I can then use in multiple programs.  I am not asking how to import a JAR but, instead, how to create a JAR from my utility class.  It seems this must have been asked elsewhere but all of the references I have found have focused on how to import a JAR file into a project.</p>
  
  <p>I am familiar with exporting my java program to a JAR file in Eclipse.  But I thought that only made a runnable JAR.  So from what I understand from the comments if I package my utility class into its own package and export to a runnable JAR I can just include that JAR in my programs to use the API.  Did not realize it was that simple.</p>
