Idea Multi-threaded multiple threads switching breakpoints running debugging tips

Multithreaded debugging settings can be consulted: http://www.cnblogs.com/leodaxin/p/7710630.html

1 Breakpoint Settings

2 test the code and then debug

3: Start Debug, we can double-click the thread that needs to be debugged in the Threads tab option

Then select the debug thread in the Frames tab option for shortcut key debugging.
