last paragraph |
The author states that - "It's possible for the main thread to call the interrupt() method just after the RandomCharacterGenerator has called the isInterrupted() method. The character-reading thread still executes the sleep() method, which won't be interrupted ( since the main thread has already executed the interrupt() method). This is another example of a race consition that we solve in the next chapter."
However if main executes the interrupt() method after RandomCharacterGenerator has called the isInterrupted() method, it's interrupted status will be set. So when the character reading thread executes the Sleep method, it doesn't go to sleep but immediately throws InterruptedException. So although it won't be interrupted, it still throws InterruptedException. I think this point could be added because although the race condition still applies, the description is ambiguous.
Thanks..
Chan.
Note from the Author or Editor:
Reword this paragraph:
It's possible for the main thread to call the interrupt() method just after the RandomCharacterGenerator has called the isInterrupted() method. The character-reading thread still executes the sleep() method, which won't be interrupted ( since the main thread has already executed the interrupt() method). This is another example of a race consition that we solve in the next chapter.
to this:
It's possible for the main thread to call the interrupt() method while the RandomCharacterGenerator is executing the isInterrupted() method. Depending on the timing, the character-reading thread could end up executing the sleep() method, which won't be interrupted ( since the main thread has already executed the interrupt() method). This is another example of a race condition that we solve in the next chapter |

Similarly, every time the variable is written, the value
must be stored in main memory. Since these operations are atomic,
we can avoid the race condition in our example by marking our done flag as
volatile.

Similarly, every time the variable is written, the value
must be stored in main memory. Furthermore, Java specifies that the
load and store operations are atomic for volatile variables, even for long and
double variables. Hence, we can avoid the race condition in our example by
marking our done flag as volatile.

We've already seen that in one case the answer is yes: you can use the
volatile keyword for an instance variable (other than a double or long).

Of course, the balance is very one sided; volatile variables can be safely used
only for a single load or store operation and can't be applied to long or
double variables. These restrictions make the use of volatile variables uncommon.

Second Last Para |
In the second last paragraph, the Callable interface is described. The method call is declared as follows.
public <V> call() throws Exception;
It needs to be changed as -
public V call() throws Exception;
as V here is the return type.
Chan.
Note from the Author or Editor:
On page 196, change the line reading
public <V> call() throws Exception;
to
public V call() throws Exception; |
