No once a thread is stopped.It goes to the dead state hence we cannot invoke methods.If a thread is in suspend state(depricated) we can invoke methods.

The post is wrong. 10 >> 2 != 5. X >> Y is the same as X / (2 ^ Y). 10 is 1010 and >> 2 is right shift two. That would result in 2 (or 10 in binary), not 5 (101 in binary).

karthik

• Nov 1st, 2005

It is right shift operator, which will produce divide by 2 action. For example 10>>2 will produce 5. the binary value of 10 is "1010" if we right shift the above by one position it will be "0101" this is equivalent to 5.
