The priority of a Newly created Thread can be changed by the method
public final void setPriority(int newPriority) ? True/False?
The answer is false, and explain as below
The priority of a newly created Thread depends on the Thread that created it。

But I think the answer explains an another concept and "true" should be the answer.

The initial priority of a new thread is indeed set equal to the priority of the thread that created it. However, the priority of a thread can be changed using the Thread.setPriority method after the new thread is created.
The following is quoted from the javadoc of the Thread class.

public final void setPriority(int newPriority)
Changes the priority of this thread.
First the checkAccess method of this thread is called with no arguments. This may result in throwing a SecurityException.
Otherwise, the priority of this thread is set to the smaller of the specified newPriority and the maximum permitted priority of the thread's thread group.
