Debugging multi-threaded applications can be tricky because whenever one thread reaches a break-point, all other threads also stopped.

Intermittent issues arising from improper implementation of equals( ) or hashCode( ) methods or data related require a more thorough debugging.


I was reading as above  about Debugging challenges.

i have not understood clearly what it means.
please advise
Any links resources ideas highly appreciated. Thanks in advance

Well that information that you are reading, is not related to Java at least...

The above is NOT true, for Java applications. If you have a breakpoint in one thread that breaks execution, all other threads continue to run.

However, the general point they are trying to make still holds. Debugging multi-threaded applications is more difficult generally than single threaded apps, because there is generally some interaction between the different threads, and this is hard to keep track of when one thread is paused but others continue to run.
