You will need to go to Project- Clean    then build your project  This will work  even when your source code does not contain any main method to run as an executable program  The  class files will appear in the bin folder of your project  in your workspace

In the case that you delete your  class file in Eclipse and then try to build it again from the  java file it will do nothing  If you try to run the  java file without the  class file you will get an error that it can not find the main class   You will either have to change and re-save the  java file then build it again  or else you have to run Clean on the project then build again
