線程類(lèi)靜態(tài)布爾型interrupted() (Thread Class static boolean interrupted())

• This method is available in package java.lang.Thread.interrupted().

  軟件包java.lang.Thread.interrupted()中提供了此方法。

• This method is used to check the thread, whether a thread has been interrupted or not.

  此方法用于檢查線程是否已被中斷。

• This method is static so we can access this method with the class name too.

  該方法是靜態(tài)的，因此我們也可以使用類(lèi)名訪問(wèn)此方法。

• The return type of this method is boolean so it returns true if the thread has been interrupted and then after boolean variable or interrupted flag is set to false else returns false if the thread has not been interrupted.

  此方法的返回類(lèi)型為boolean，因此如果線程已中斷，則返回true，然后在boolean變量或interrupted標(biāo)志設(shè)置為false之后，否則返回false，如果線程尚未中斷。

• This method raises an exception.

  此方法引發(fā)異常。

Syntax:

句法：

static boolean interrupted(){}

Parameter(s):

參數(shù)：

We don't pass any object as a parameter in the method of the Thread.

我們不會(huì)在Thread方法中將任何對(duì)象作為參數(shù)傳遞。

Return value:

返回值：

The return type of this method is boolean, it returns true or false and if the thread has been interrupted so it returns true and then set a boolean flag to false else return false.

此方法的返回類(lèi)型為boolean ，它返回true或false；如果線程已中斷，則返回true，然后將boolean標(biāo)志設(shè)置為false，否則返回false。

Java程序演示interrupted()方法的示例 (Java program to demonstrate example of interrupted() method)

/* 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 classpublic 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(); } }
