How to set name to the thread?

Check the Thread constructors, there are a few with a String name parameter. Or you can call setName(String) on an existing Thread.

You can easily pass a thread name in Its Constructor, like:

Thread foo = new Thread("Foo");

... or by calling Thread#setName:

public final void setName (String threadName)

Sets the name of the Thread.

as thread.setName("Thread-11"); or like Thread.currentThread().setName("Thread-11");
