1. TreeMap stores what in sorted natural order? Keys or Values
2. Does Vector also store objects in FIFO order?
3.A higher priority thread will prevent lower priority thread to get access to cpu-Its given this statement is false..Why??

1 TreeMap is sorted by keys.
2. Think of Vector like an array or ArrayList, it adds to the bottom of the list
3. Thread priority is just a suggestion to the JVM, not a guarantee that one thread will take precedence over another. Think of it like a lottery. A high priority thread has 10 entries, and a low priority thread has 3 entries. What is the probability that the entry drawn is from the high or low priority thread. There is still a chance the low priority gets drawn.
