Practice with thread priority

nice thanks

For the second task get rid of (last) constructor: // public MyThread(ThreadGroup group, Runnable target, String name, long stackSize, boolean inheritThreadLocals) { // super(group, target, name, stackSize, inheritThreadLocals); // setPriority(priorityIncrement()); // }

first task

//change list 
List<String> list = new CopyOnWriteArrayList<>();
