The IDE supports multiple debuggers with multiple types. A debugger type is a collection of settings that tell a particular debugger
how to function.
You can view the debugger types in your version of the IDE by using the Options window. The debugger types are listed under Debugging and Executing Debugger Types.
By default, the IDE has four debugger types:
Additional debuggers might be installed in your version of the IDE by extension modules. You can install the JDK 1.1 debugger from the Update center. This debugger runs with J2SE v1.3.x software or earlier. See Updating the IDE for instructions.
One debugger type is selected as the default debugger. The default debugger type is used for all files and templates for which you have not specifically assigned a debugger type. You can view the default debugger type by opening the Options window, expanding the Editing node, and selecting the Java Sources node.
If you are not satisfied with how your file will be debugged, you can modify the properties of the debugger type that is assigned to the file. Or, if you want to preserve the properties of that debugger type, you can create a new debugger type and assign it to the file.
