Sleep is the thread class method that threads use to control their own processes, such as having a thread to tell the time, printing out a moment in each second, and then I need to add a single call to the Print method to perform it every second. It's like an alarm clock.
Wait is a method of the object class, used for communication between threads, which causes the process that currently owns the object lock to wake up when the oth
With the progress of Windows system, Microsoft also increasingly emphasizes the importance of sleep function. After sleep, the user can wake up the system in a few seconds, and the shutdown and then boot, I am afraid that time will be much longer, especially for Vista, such as the start time of the critically criticized system. As a result, Microsoft intends to significantly shorten the system startup time
One user consulted about the ability to set a timed shutdown for a Mac. In fact, OS X system comes with this related function, but "hidden" a bit deep. Here to share with you:
Open System Preferences-Energy saver, then click on the "Timing" button;
Tick the second check box (the one in front of sleep) and select Shut Down/restart/sleep in the dropdown menu;
Set the time on the right.
Note: The above met
For the Sleep () method, we first need to know that the method belongs to the thread class. The wait () method is part of the object class.The sleep () method causes the program to pause execution for the specified time, giving up the CPU to that other thread, but his monitoring state remains, and when the specified time is up, it will automatically resume its running state.During the call to the
OneSleep is a thread-class method that causes this thread to pause execution for a specified time, giving the execution an opportunity to another thread, but the monitoring State remains, and then automatically resumes after the call to sleep does not release the object lock. The synchronization method inside cannot be called because the object lock is not released.Sleep () causes the current thread to go to a standstill (blocking the current thread),

Definition and usage
The sleep () function delays code execution for several seconds.Grammar Sleep (seconds)seconds required. The pause time in seconds.return value
If successful, returns 0, otherwise false.Error/exception
If the specified description seconds is a negative number, the function generates a e_warning.
Example
Output:

This article mainly introduces the simple example of using the PythonSleep sleep function. This article provides two Implementation examples. For more information, see the time module in Python programming to sleep the program, the specific method is time. sleep (number of seconds). The "number of seconds" is measured in seconds, which can be Decimals. The value

The following figure shows the life cycle of the WP7 program:The sleep state and the tombstone state are confusing. The program stops running during sleep state, but the difference is that the entire process still exists in the memory. When this program is restored, you do not need to create a new instance. In this way, the program recovery and switching are accelerated, and we do not need to restore the to

Start with Java if you are familiar with multiple threads.
Read this articleArticleAll of my friends know the differences between processes and threads, and why multithreading is required.
The main sources of these two methods are sleep, which is used for thread control, and wait is used for inter-thread communication. The methods supporting wait include policy and policyall.
Difference 1:
Sleep
There are two useful functions in the Java Thread class: Sleep and yield. Sleep means the thread sleeps for a certain period of time, that is, the CPU is handed over for a period of time. yield is used to imply that the system gives control of the CPU. These two functions are particularly useful in multi-threaded development. They can allocate CPU resources reasonably and improve program running efficiency.

We may often use the thread. Sleep function to suspend the thread for a period of time. Do you understand the usage of this function correctly? Consider the following two questions:
Suppose it is 12:00:00. 000. If I call thread. Sleep (1000), this thread will not be awakened at 12:00:01. 000?

When we are not away from the computer for some time, the system will also automatically enter the sleep state, if the user does not have a special setting for sleep state, the system will run after the sleep of some software or programs are automatically stopped or disconnected, especially when downloading some resources will also stop downloading, which caused
"Sleep" is an energy-saving state that enables the computer to quickly restore full power when you need a computer to restart its work. Keeping your computer in sleep is like pausing the player, the computer stops working immediately, and is ready to continue working.
