Java Thread类的静态布尔型interrupted()方法（带示例）
线程类静态布尔interrupted()
软件包java.lang.Thread.interrupted()中提供了此方法。
此方法用于检查线程是否已被中断。
此方法是静态的，因此我们也可以使用类名访问此方法。
此方法的返回类型为boolean，因此如果线程已中断，则返回true，然后将boolean变量或interrupted标志设置为false后，否则返回false；如果线程未中断，则返回false。
此方法引发异常。
语法：
static boolean interrupted(){
}参数：
在Thread方法中，我们不传递任何对象作为参数。
返回值：
此方法的返回类型为boolean，返回true或false，如果线程已中断，则返回true，然后将boolean标志设置为false，否则返回false。
Java程序演示interrupted()方法示例
/* 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
{
//覆盖run()Thread类的方法
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();
}
}输出结果
E:\Programs>javac InterruptedThread.java E:\Programs>java InterruptedThread This thread has not been interrupted This thread has not been interrupted This thread has not been interrupted Is thread Thread-1 has been interrupted: false This thread has not been interrupted This thread has not been interrupted This thread has not been interrupted This thread has not been interrupted
