How to create a subclass in Eclipse?

During lecture, my professor very quickly created a subclass in Eclipse.

The result has the "extend" keyword added to the subclass. I didn't see what buttons he clicked.

Does anyone know where should I click? (I think he right clicked on the current class in the package explorer, then New ==> class, then I'm lost on what to select).

When you create a class, replace the name of superclass with the your superclass name, that will do the job.

Rt click on class > Show in Package Explorer Ctrl-N > Class The selected class will be automatically populated as the super class and you can enter you class name to derive from that

When you are viewing the class you want to subclass, open Type Hierarchy (press F4). Right click on the parent-to-be class, and in the menu go to new -> class ( or Ctrl-n , class ).

You can try to bind Keys for New (New Wizard: Class) command (for eg.: Ctrl + Alt + N) by open Window> Preferences > General > Keys.

And then, on new wizard window, change the Superclass box.

Right click on project name on Package Explorer + Add New Class + Type package Name, Name (sub-class name), and Super class (or Click on Browse to choose super class).
