JAVA thread control, java thread
You can use the thread method to perform basic thread control. Besides the known start, run, and sleep methods, there are also isAlive, currentThread, and inte

In the Friday and the weekend, work to sneak in, looking at the Java cocurrent also by the way the Thread.Interrupt and Java 5 after the implementation of the Locksupport.
Before introducing, let's throw a few questions.
The relationship between Thread.Interrupt () method and Interruptedexception anomaly? is the interruptedexception exception triggered by the interrupt
keyword of the Java language, so it is a built-in feature. Lock is a class that enables synchronous access.
2. synchronized does not need to manually release the Lock. After the synchronized method or synchronized code block is executed, the system will automatically let the thread release the occupied Lock. The Lock must be manually released, if the lock is not released, a deadlock may occur.Ii. Common cl
Thread basics: thread (3) -- basic thread operations in JAVA (medium)1-4. Pay attention to the use of the synchronized keyword.
In the previous article, we mainly explained the working principle and operation method of the "Object lock" in the thread. When explaining the syn

2. sleep ()
Sleep () may throw a required check exception for InterruptException, and force a try/catch check exception in java.
3. thread
One, the phenomenon of Java interruptionFirst, look at some of the methods in the thread class:
public static Boolean interrupted
Test if the front thread has been interrupted. The interrupt state of the thread is purged by this method. In other words, i

The Thread Pool is useful for limiting the number of threads running at the same time in an application. Because each time a new thread is started, there will be correspo

A Futuretask object can be wrapped on an object that calls callable and runnable, because Futuretask also calls the Runnable interface so it can be submitted to executor for Execution.What is the difference between interrupted and Isinterruptedd methods in java?The main difference between interrupted () and isinterrupted () is that the former clears the interrupt state and the latte

In the previous article, we created a thread when we used the thread, so it was easy to implement, but there was a problem:
If you have a large number of concurrent threads, and each thread is finished with a short task, creating a thread frequently can g

It has the methods of starting and canceling operation, whether the query operation is complete and retrieving the result of operation. The result can be retrieved only when the operation is compl
