eclipse - Java package in package?

Question

I'm using eclipse 3.8 indigo and I don't know why, when I'm creating a new package the destination of the new package goes outside. I want to create new packages within a package: package in package. I tried to copy / paste the newly created package or to move, but it just copies.

For example, I want to create different packages: dialogs, views, tables, etc. in my main source package. For example:

com.new.application // this is the the main package created by wizard
com.new.application.view // package that contains all views.

In reality there is no such thing as a sub-package in Java - each package is a completely separate entity, with the names being seemingly hierarchical only for convenience. For example, items with default visibility are not visible in sub-packages, despite what one might expect.

If your problem has more to do with presentation and aesthetics than substance, then perhaps what you are looking for is the hierarchical package presentation setting in the Eclipse Package Explorer: click on the little downward triangle/arrow at the top right of the package explorer and select "Hierarchical" in the "Package presentation" submenu:

This is a global setting and will affect all your opened/un-opened projects.
