Java Thread类的boolean isInterrupted()方法（带示例）
线程类布尔isInterrupted()
包java.lang.Thread.isInterrupted()中提供了此方法。
此方法用于检查线程是否已被中断。
此方法不是静态的，因此我们也无法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；否则，如果线程未中断，则返回false。
我们需要记住，如果线程已中断，则此方法返回true，然后不像方法那样将标志设置为falseinterrupted()。
此方法引发异常。
语法：
boolean isInterrupted(){
}参数：
在Thread方法中，我们不传递任何对象作为参数。
返回值：
该方法的返回类型为boolean，返回true或false，并且如果线程已中断，则返回true，否则返回false。
Java程序演示isInterrupted()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.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();
}
}输出结果
