() or Notifyall. This method can only be called in a synchronous method . If the current thread is not the holder of a lock, the method throws a illegalmonitorstateexception exception.void Wait (long Millis) and void wait (Long millis,int Nanos)Causes the thread to enter a wait state until it is notified or passes the specified time. These methods can only be called in a synchronous method . If the current thread is not the holder of a lock, the method throws a illegalmonitorstateexception exce

Recently, due to the needs of the projectYou need to use the sleep function to take a bunch of data from the database to perform certain operations.Sleep is waiting for at least one hoursI've been tested before.Using the sleep function to complete a few hours of operation is feasibleBut it's a scary question.The program uses sleep to find that the information can

===============windows Platform: ======================about void Sleep (DWORD dwmilliseconds); functions, many people feel that it is telling the system how many milliseconds to delay to execute the following code.However, in a non-real-time multitasking system such as windows, we cannot estimate how long we will sleep. Because a thread is not always executed. It is suspended by the system after a period o

Last time, I gave a general overview and summary of Java thread. Of course, most of them are in theory. This time I will explain two common and confusing methods in thread and use the example Code ... FDifferences Sleep () methodSleep () causes the current thread to enter the stuck state (blocking the current thread), giving rise to the usage of the cup to prevent the current thread from occupying the CPU resources of the process independently, to

There is a new sleep pattern in the Windows7 system, where the energy consumption is very low when the computer is in sleep mode. But when you wake up a system that Win7 sleep, it's very fast, and you don't have to wait for a long time to start like XP. So set the sleep mode correctly, not only save energy, but also

1. Introduction to sleep (suspend)In Linux, sleep mainly involves three steps:1) Freeze user-State processes and kernel-state tasks2) Call the suspend callback function of the registered device in the order of registration3) sleep the core device and enable the CPU to sleep. The frozen process is the kernel that sets t

task_uninterruptible ignores the signal, while a process in the task_interruptible state receives a signal that wakes up early and signals the signal. Processes in both states are on the same waiting queue, waiting for certain events to run.1. Waiting QueueHibernation is processed by waiting for a queue. The wait queue is a simple list of processes that wait for certain events to occur. The kernel uses wake_queue_head_t to represent the waiting queue. The wait queue can be created statically by

Now many people are starting to use the Win7 system, if you leave the computer for a period of time, do not want to shut down but also want to save electricity how to do, this tutorial for you to introduce the Win7 sleep settings skills. One, Windows7 fast sleep has a trick Click the Start menu, turn on the control Panel → hardware and sound → Power options. Click the Change schedule settings link next to

The meaning of Sleep (0) is to discard the current thread execution time slices and put itself in the waiting queue. At this point the other threads will get the time slice to program the program. Sleep (0) can reduce the execution speed of the current thread, such as: Now there are 100 threads in the system (assuming a thread bar) to perform different tasks, and they perform the same priority, and each tim

C language Pause () function: Let the process pause until the signal appearsheader file: #include To define a function: int pause (void); Function Description: Pause () will suspend the current process (go to sleep state) until it is interrupted by a signal (signal). Return value: Returns only-1. Error code: EINTR has a signal arrival interrupt this function. C language Alarm () function: Set signal transmission alarm Cl

The problem is that I bought a solid-state drive to reload the Win7 system, before the mechanical hard drive put power options off the monitor and the computer went into sleep mode both chose "never", the computer will not go to sleep state. I can remote my company's computer at home or in the field. But found the newly installed SSD computer set this power option, will still "

What do you know about sleep every day? The US National Sleep Foundation conducted a nationwide "Sleep provider" test. You might as well try it. 1. The brain is resting during sleep. Error. The brain remains very active during sleep, preparing for the next day's awaken

Reprint: http://blog.csdn.net/clam_clam/article/details/6803667The difference between sleep () and wait ()Multithreading in Java is a preemptive mechanism rather than a time-sharing mechanism. Threads have the following states: Can run, run, block, die. The preemption mechanism refers to having multiple threads in a running state, but only one thread is running. when there are multiple threads accessing the shared data, the threads need to be synchro

Java. lang. ThreadOfSleep ()Method to pause the current thread for a period of time (unit: milliseconds ). Note that the parameters of the sleep () method cannot be negative. Otherwise, an IllegalArgumentException exception is thrown. In addition, there is another method.Sleep (long millis, int nanos)This method can be used to pause the current thread in millis millisecond nanos nanoseconds. Note that the value range of the parameter nanos is [0, 9999

Thread. Sleep (long millis) and thread. Sleep (long millis, int Nanos) Static Methods force the currently executing thread to sleep (pause execution) to "slow down the thread ".When a thread is sleeping, it sleeps somewhere and does not return to a running state before waking up.When the sleep time expires, the system

There are three ways to sleep the system in wince:1. Select suspend from the Start Menu.2. You can press the power button to request the system to enter sleep mode (for example, if you want to press and shut down for a long time or press sleep for a short time)3. the user has not been operating for a long time. The system status is changed from power_state_on to

1. The two methods come from different classes , sleep comes from the thread class, and wait comes from the object class. Sleep is the static class method of thread, who calls who goes to bed, even if the A-line Chengri calls the B's sleep method, actually still a goes to bed, wants to let B thread sleep to call in B'
