c. The Thread moves into the Not-Runnable state
d. The Thread moves out of the Not-Runnable state
e. An InterruptedException is thrown when the Thread moves into the Running state

d. Calling Thread.interrupted after the InterruptedException is thrown will return true

hi ,
can anyone explain me the difference between the two things??
answers for the first is given by b and for the second given as b,c...
as far as i know...blocking is that one which waits for any resources(I/O)..it is in non-runnable state and when interrupted it goes into ready state..and Calling Thread.interrupted calling this i think shud return me true..but the answer says totally differ..i missing somewhere ..can anyone explain me.....

The answers are compatible with the javadoc on Threads. Therer is a different behavior if this method dependent of the Thread's status.
In case it's blocked the interupt status is cleared (moved to runnable) and an InteruptException is being thrown, else the interupt status will be set.
