Eclipse Tips : Type Filters in Eclipse

This tutorial explains one of the cool feature in Eclipse, that is Type Filters to filter the suggestions listed as autocomplete for your object. If you type a class name with dot, Eclipse would suggest the list of methods in that class or object reference. Typically it retrieves all the methods from the super classes. If you look at the Object class, we have several methods which are rarely used by the programmers but it is suggested every time. We can filter the types which we don’t want in the suggestion box by adding the package or class name in the Type Filters option in Eclipse.

This tutorial provides crisp instructions to enable that feature. Look at the below screenshots for more details.
