Java class library

Question

Can we import this three ijava class and method library or whatever it's name in
sololearn Java?
import java.concurrent.Executors;
import java.concurrent.ExecutorService;
import java.concurrent ThreadPoolExecutor;

Answer 1

Sololearn have limited support for java libraries..
I think it can't support multi threads properly.. Just considers sequential flow instead of threads..

Answer 2

Try it this way

import java.util.concurrent.Executors;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.ThreadPoolExecutor;

You are missing the .util.

Answer 3

What is not working?
I get all three classes Imported w/o any error.

Answer 5

It doesn't work. I have imported java.util.concurrent Executors and Java.util.concurrent.ExecutorService.

Answer 6

Yes, But I tried not to use those 3 Java classes. Insrtead of import those classes, I juat import secure random generator to generate random numbers as timer for thread. I use conventional method for creating a thread by implementing Runnable interface, and it run successfuly.
