Is that it is not possible to predict, and would be very difficult to measure. How long does a Java thread own a CPU time slice? (And my guess is that it is not evidence of any significance at all.) In short, whatever output you see from that program, it will not be clear evidence of time slicing behavior. has some hidden synchronization going on behind the scenes so that two threads printing at the same time don't cause corruption of the shared buffer data structures. It can also happen when a thread does blocking I/O, or when it attempts to acquire a Lock or a mutex, or wait(.) or sleep(.) or something similar. Java thread rescheduling doesn't just occur due to time slicing. It is also possible to create and delete system resources from threads during the normal operation of the application. (A low priority thread's time-slice may be cut short if a high priority thread needs to be scheduled.) The txapplicationdefine function defines all of the initial application threads, queues, semaphores, mutexes, event flags, memory pools, and timers. If there are higher priority threads running in the Java application itself or in other parts of the system, that will perturb time slicing. And the number of them that the OS makes available to your Java application. The output is likely to depend on the number of cores (or hyperthreads) on your system. However, there are a number of factors that could explain why the output is different to what you expect. So it is not possible to explain the former, or why the latter may be off-base. For example, if the unit is MONTH and the slicelength is 2, then each slice is 2 months wide. how many units of time are contained in the slice). This indicates the width of the slice (i.e. The expression must be of type DATE or TIMESTAMPNTZ. The JDK includes tools useful for developing and testing programs written in the Java programming language and running on the Java TM platform. The function returns the start or end of the slice that contains this date or time. First of all, you don't tell us what output you are seeing and what you are expecting to see. Java SE 8 Archive Downloads (JDK 8u202 and earlier) The JDK is a development environment for building applications using the Java programming language.
