How to create package inside a project?

What Is a Package? A package is a namespace that organizes a set of related classes and interfaces. Conceptually you can think of packages as being similar to different folders on your computer. You might keep HTML pages in one folder, images in another, and scripts or applications in yet another. Because software written in the Java programming language can be composed of hundreds or thousands of individual classes, it makes sense to keep things organized by placing related classes and interfaces into packages. -> Right click on the Project (Make sure you should right click on project, because you are creating package inside the project). -> Go to New. -> Click on Package. -> In New Java Package window, enter package name in Name text box. -> Now click on Finish . -> Now you can see the package inside the project at Project Explorer area. Now your package is ready.
