What is the difference between the Eclipse Package Explorer and the Eclipse Project Explorer?

Question

It seems to me these two views are virtually identical, especially since Galileo. Is this true, or am I missing out on some features of one or the other?

Answer 1

• Project Explorer - This is an instance of the CommonNavigator that is provided by the org.eclipse.ui.navigator.resources plugin. It provides a view of the workspace and has a large number of NCEs(Navigator Content Extensions ) contributed for resources, Java, C, Web Tools, Data Tools, PHP, etc. Source
• Project Explorer additional nodes for web projects, enterprise projects, spring beans and web services.
• Package Explorer - Provided by the Java Development Tools (JDT) UI project, this provides a view of Java classes for the workspace.
