Step filters are commonly used to filter out types that you do not wish to see or step through while debugging.
For example, if you did not want to the see or step through anything from the class java.lang.Object, you would add this to the list of filtered types. Adding types to the list of those to be filtered can be done in one of two ways:
  - Via the context menu - Right click on the stack frame for the type you wish to filter and use the Filter Type or Filter Package command. 
- Via the   Java > Debug > Step Filtering preference page. Java > Debug > Step Filtering preference page.
