  • In batch file? Linux, bash, or what? Or is it really a Java question? Do you want to do it inside your java code? – Dariusz Jun 05 '13 at 11:14
  • yes in windows and yeah I want to do it in my java code – user2455242 Jun 05 '13 at 13:01
  • @AlecHenderson_v1.00 I have already tried this but it reads all the running threads in system but not in the batch file. – user2455242 Jun 05 '13 at 13:04

You can get running threads like this:

Set<Thread> threadSet = Thread.getAllStackTraces().keySet();

Then output the information you need of each thread. Once donecreate a batch file which calls your java file using: java ProgrammName

The top rated answer to this question: kill -3 to get java thread dump suggests using jstack. Run this on the command line using the pid (from task manager) and redirect the output to a file. Then read it with your batch file.

For example:

jstack -l 5980 > threaddump.txt
