java.util.concurrent.ExecutionException exception,This is because our submitted task java.util.concurrent.Callable allows any exception to be thrown in the call () method, and the regular thread execution may throw a runtimeexception, so it simply wraps up all the exceptions, Executionexception thrown as an exception that occurs during execution.The above is the entire anomaly system, all concurrent operation exceptions can be attributed to the above categories.In many cases processing time is

sub-array there are several pairs of reverse pairs (currently there are two elements, reverse to add 2,2+2=4), 7>6, after comparing the P1 point to the value into the auxiliary array, The auxiliary array now has a number 7 and then moves the P1 forward one point to 56. Again determine the value that P1 and P2 point to, p1 is less than P2, because P1 points to the largest value in the first subarray, so there is no number in the sub-array that can be reversed against the 6 that the current P2 po

In Python 1.5.2 and previous versions, the module exists only on Unix platforms. After 2.0, the function is also implemented under Windows.
