To open the Integrated Debugger browser, select Debug > Debugger from
any Window menu or click the Debug toolbar button . This will open the
Debugger browser to the Debug page, which lists running threads, their
states, and their methods' visible variables.
If you click the Breakpoints tab, or if you selected Debug > Breakpoints from the Window menu, then the Debugger browser opens to the Breakpoints page, which summarizes all methods in the workspace that have breakpoints set.
If one or more program are running when you open the Debugger, then the running threads are listed in the All Programs/Threads pane of the Debug page. If you suspend the thread, you can look at the methods on the thread, and inspect the methods' visible variables.
If you leave the Debugger open and start a program, the new program's threads will be added to the All Programs/Threads pane.
