Eclipse Debug Multithreading Overview

Used to have a lot of thread development, multithreading development is a little bit of experience, but the beginning of multithreading development, encountered many walls. But in a sense, a good tool always gets the best of it. The tool I use is eclipse, in the development of multithreading, its debug mode is able to directly simulate the multithreaded environment, there are a lot of data online, but most of them are not very full. I hope I can record some of my experience, I hope to help also for multi-threaded development and tangled friends.

First write a simple multithreaded test case:

Package com.wxw.debug;

Publicclass Testmain extends Thread {

@Override

Publicvoid Run () {

System.out.println ("Hello World");

}

Publicstaticvoid Main (string[] args) {

Testmain T1 = new Testmain ();

Testmain t2 = new Testmain ();

T1.start ();

T2.start ();

}

}

This piece of code, the console prints out two lines

Hello World

Next, you'll demonstrate how to use the debug mode for step-by-step execution, and then gradually apply the knowledge extension

Location of breakpoints

Here is a point to note that the location of the breakpoint must be correct, run method or run after the call method, otherwise, the program ran out, debug mode is also only a main thread in the run, well, directly to see the results.
