The following preferences can be set using the Java > Debug > Step Filtering preference page.

These preferences are used to configure step filters and step filtering options.

Defined step filters | This is a listing of all of the defined step filters (the listing itself) and whether the step filters are in use or not (the checked state of step filter) |
Add Filter button | Used to add a new step filter that is based on a regular expression |
Add Class button | Used to add a new Java class to the listing of step filters |
Add Packages button | Used to add new Java packages to the listing of step filters |

Filter simple getters | This option controls if simple Java bean-style getters should always be filtered or not while stepping | Off
Filter simple setters | This option controls if simple Java bean-style setters should always be filtered or not while stepping | Off
Filter constructors | This option controls if constructors should always be filtered or not while stepping | Off

Step through filters

This option controls step filters to always return from a filtered location or step through to a non-filtered location.

For example, if `java.util` is a filtered location, stepping into code in `HashMap` could result in a call-back to your application code to check the equality of an object. If you choose to Step through filters a step into would end up in your application code. However, when the Step through filters option is disabled, a step into `HashMap` would behave like a step over.
