can anyone help me solve the issue that I have ? in fact when I create a project on eclipse, the bin folder doesn\'t display and I am able to create a javadoc for my project
To change this behaviour and hide the “.class” files you need to do the following.
Find your class output folder in the “Project explorer” window. This is usually called “bin” or “target” for Maven projects
Right-click this folder and click “Properties”
Tick the “Derived” checkbox and click “OK”
“.class” files will now be hidden in future.

Your question is a bit vague but try right clicking on the project and choosing build path, and see if the output directory for your java classes is set to bin. It may not appear in your unless you add some Java source code
If your Eclipse version doesn't allow you to show "Java Output Folders" as mentioned by nanda, then try the Navigator View (From the main menu: Window > Show View > Navigator). The Navigator View shows the bin folder.
I don't know what the reason for your question but you can see the bin directory in Project Explorer (not Package Explorer). Here you click the triangle and select Customize View... and remove the click on Java output folders
