You can use the activeCount method to get an upper bound for the array; this method returns the number of threads put into the array.

Parameters: list An array to be filled with the thread references • THReadGroup getParent() gets the parent of this thread group. • void interrupt() interrupts all threads in this thread group and all of its child groups.

Depending on the order in which the data were accessed, corrupted objects can result. Such a situation is often called a race condition. An Example of a Race Condition To avoid corruption of shared data by multiple threads, you must learn how to synchronize the access. In this section, you'll see what happens if you do not use synchronization. In the next section, you'll see how to synchronize data access. In the next test program, we simulate a bank with a number of accounts. We randomly generate transactions that move money between these accounts.
