Java中interrupted（）和isInterrupted（）之间的区别

Java中的interrupted()和isInterrupted() (interrupted() and isInterrupted() in Java)

Here, we will see how isInterrupted() differs from interrupted() in Java?

在这里，我们将看到isInterrupted()与Java中的interrupted()有何不同？

isInterrupted() (isInterrupted())

This method is available in java.lang package.
此方法在java.lang包中可用。
This is the non-static method so this method is accessible with the class object.
这是非静态方法，因此可通过类对象访问此方法。
This method is used to check whether a thread has been interrupted or not interrupted.
此方法用于检查线程是否已中断。
The return type of this method is boolean so it returns true if the thread has been interrupted else return false.
此方法的返回类型为boolean，因此如果线程已中断，则返回true，否则返回false。
In case of isInterrupted() method, we need to notice that this method returns true if the thread has been interrupted and then after interrupting it does not again set the boolean variable as false like as interrupted() method else returns false.
对于isInterrupted()方法 ，我们需要注意的是，如果线程已被中断，则此方法返回true，然后在中断之后不再将布尔变量设置为false，就像interrupted()方法一样，否则返回false。
The syntax of this method is given below:
该方法的语法如下：
```
public boolean isInterrupted(){
}
```

Example:

例：

/*  We will use Thread class methods so we are importing the package 
but it is not mandate because it is imported by default
*/
import java.lang.Thread;
class InterruptedThread extends Thread {
// Overrides run()  method of Thread class
public void run() {
for (int i = 0; i <= 3; ++i) {
/*  By using interrupted() method to check whether this thread 
has been interrupted or not it will return and execute 
the interrupted code 
*/
if (Thread.currentThread().isInterrupted()) {
System.out.println("Is the thread" + Thread.currentThread().getName() + "has been interrupted: " +  Thread.currentThread().isInterrupted());
} else {
System.out.println("Is the thread" + Thread.currentThread().getName() + "has been interrupted: " +  Thread.currentThread().isInterrupted());
}
}
}
public static void main(String args[]) {
InterruptedThread it1 = new InterruptedThread();
InterruptedThread it2 = new InterruptedThread();
/*  By using start() method to call the run() method of Thread class 
and Thread class start() will call run() method of 
InterruptedThread class
*/
it2.start();
it2.interrupt();
it1.start();
}
}

打断() (interrupted())

This method is available in java.lang package.
此方法在java.lang包中可用。
This is a static method so this method is accessible with the class name too.
这是一个静态方法，因此也可以使用类名访问此方法。
This method is used to check whether a thread has been interrupted or not interrupted and then set interrupted flag status.
此方法用于检查线程是否已被中断，然后设置中断标志状态。
The return type of this method is boolean so it returns true if the thread has been interrupted else return false.
此方法的返回类型为boolean，因此如果线程已中断，则返回true，否则返回false。
In case of the interrupted() method, we need to notice that this method returns true if the thread has been interrupted and then after interrupted flag or boolean variable is set to false else returns false.
对于interrupted()方法 ，我们需要注意的是，如果线程已被中断，则此方法返回true，然后在interrupted标志或布尔变量设置为false之后，否则返回false。
The syntax of this method is given below:
该方法的语法如下：
```
public static boolean interrupted(){
}
```

Example:

例：

/*  We will use Thread class methods so we are importing 
the package but it is not mandate because 
it is imported by default
*/
import java.lang.Thread;
class InterruptedThread extends Thread {
// Overrides run()  method of Thread class
public void run() {
for (int i = 0; i <= 3; ++i) {
/*  By using interrupted() method to check whether this 
thread has been interrupted or not it will return and 
execute the interrupted code 
*/
if (Thread.interrupted()) {
System.out.println("Is thread" + Thread.currentThread().getName() + " has been interrupted and status is set to " + " " + Thread.interrupted());
} else {
System.out.println("This thread has not been interrupted");
}
}
}
public static void main(String args[]) {
InterruptedThread it1 = new InterruptedThread();
InterruptedThread it2 = new InterruptedThread();
/*  By using start() method to call the run() method of 
Thread class and Thread class start() will call run() 
method of InterruptedThread class
*/
it2.start();
it2.interrupt();
it1.start();
}
}
