Why does ThreadMXBean.getThreadCpuTime return the same time?

Asked 2020-May-28 at 08:52

I try to use ThreadMXBean.getThreadCpuTime to get the CPU time of main thread. However, I get the the same time although the thread must have done some work which needs time. Now, I doubt the accurancy of using ThreadMXBean.getThreadCpuTime to get the CPU time. My example code is below,

The time you see its based on your computer's OS behaviour, how the OS performs the task. 187ms you see it now, but if you restart your computer or run this code in another time then you will not see consistent 187ms time. I ran you code and this is the result:

QUESTION

Is it possible to only use lock and condition to get ABCABC result

Asked 2020-May-26 at 05:37

I try to get the result like this, ABCABCABCABCABC. I have already implemented it by using a flag to indict the current print state. However, I think I can remove the flag to implement the same function. But after my modification, the code is blocked in the construct of AlternateDemo. I could not find the root cause. Could anyone tell me the reason?

My code is below.

NOTE: thread-A is like A, thread-B is like B, and thread-C is like C

QUESTION

What does `synchronized` do when I get continuous result from the same thread?

I try to do some exercises for producers and consumers. Code is below, which is thread-safe, but this code does not solve the synchronization between producers and consumers.

ANSWER

Answered 2020-May-25 at 07:38

I think that when the "product is full", the producer should wait for the consumer to consume the product and when the "product is lack", the consumer should wait for the producer to produce the product. in this way the two threads will work "in tandem", while now they are working "sequentially".

this can be acheived easily using wait() and notify()/notifyAll() methods.

changing the Clerk class using wait() and notifyAll() to implement the "waiting" leads to your expected output:

QUESTION

Why will the CPU time be different without using volatile?

Asked 2020-May-25 at 00:49

Code 1: In this code, I use the System.out.println(); to get the value changed by other thread instead of using volatile.

ANSWER

Answered 2020-May-24 at 09:21

In Code 1, time spent in the OS Kernel to print the blank line (and maybe scroll the terminal window), is time not spent in the Java thread, so not all the CPU time is counted when printing.

The loop in Code 2 is a pure CPU loop, so all the time is spent by the Java thread.

File names When I run this, the slideshow doesn't appear. Do I need to install anything or am I missing a DOM? When I do open the file in the browser and then open console and enter my js code, the slideshow does appear. Maybe I need to update something or add an ext to vsc? Thank you in advance from this #codenewbie

Also, apparently if you run the snippet here, the slideshow appears. Just not when i run the page from VSC.

ANSWER

Answered 2017-Jul-08 at 15:03

Your Runnable run method, is only incrementing num when its prime and hence when it encounters 4 which is not prime its not incrementing num and your program is in that state for rest of period when its running. Fiddled with below mentioned piece which makes it go beyond that point and break at 100.
