There are hints, where You should google for: http://stackoverflow.com/questions/74674/how-to-do-i-check-cpu-and-memory-usage-in-java – icbytes Jun 06 '13 at 12:11

to simplify, the difference between threads and processes is that threads in a process share the same memory address space, so it can be said that the process's memory belongs to all the threads at the same time. – SirDarius Jun 06 '13 at 12:16

3What is "cpu memory". That is two different concepts. If you want memory then remove the word CPU. – Gray Jun 06 '13 at 12:16

You can't. There is no way to tie heap-memory resources created in the JVM to the thread that created it since all threads share a common heap. There are stack memory allocated to each thread but I know of no way to determine how much stack space has been consumed by each thread.
A profiler is the best way for you to go but I don't think even they show you the owning thread. You may be able to infer this information from the object call stack however.

You want to do that in your code or with a tool ?
With a profiler like VisualVM, this is easy. But in Java, it is harder because the JVM treats the heap as shared not separated heaps for threads.

1Yes. If you go in "Sampler", then choose "Memory", you have a tab with per thread memory allocation. – Baptiste Wicht Jun 06 '13 at 12:56
