Thread 1-thread, Thread thread

Select two cities as the pre-selection destination. Implement two independent threads to display the city names for 10 times respectively. After each display, sleep for a random period of time (within ms). When the display is complete, decide the city to go. Use the Runnable interface and Thread class respectively.
