What is the difference between suspend and sleep

The question that was popped-up to us was what is the difference between suspend , wait and sleep methods of Java? Though minute, there is a subtle difference among the three. What this means is, while calling Thread.

The t. It suspends the thread on which it is invoked. If the target thread holds a lock on the monitor protecting a critical system resource when it is suspended, no thread can access this resource until the target thread is resumed. If the thread that would resume the target thread attempts to lock this monitor prior to calling resume , deadlock results.

The parent to all Java classes. The wait method causes the current thread call it T to place itself in the wait set for this object and then to relinquish any and all synchronization claims on this object. Thread T becomes disabled for thread scheduling purposes. Later, another thread can synchronize on the same lock object and call lock.

This wakes up the original, waiting thread T. You explained it well. Another useful article which I came across while searching was wait and sleep difference.

Do you know how to make your site mobile friendly? All you need to do is first check if your computer hardware is compatible with the mode.

Your PC will turn off. Next, turn ON the computer and check if the session you had before you entered the pm-hibernate command is intact or whether you logged into an empty desktop. If your session is lost, it implies your PC will not hibernate. Next, check if your swap partition is at least as large as your available RAM.

Swap size twice the size of RAM …. I think it is absurd to have a swap of 16GB — when you already have 8 GB of memory. Or is Linux and the linux apps that bad in memory management? Oh, And i have used hibernate in windows for maybe 20 years now. Such a disappointment. I believe you, when you say that implementing hibernate in an OS is difficult.

Still Windows has done it, on millions of different computer configurations, for a long time. It is not meant that way. I am just disappointed that something common as hibernate is so hard to configure in Linux. Save my name, email, and website in this browser for the next time I comment. Sign in.
