线程中断
线程中断
线程中断即线程运行过程中被其他线程给打断了，它与 stop 最大的区别是：stop 是由系统强制终止线程，而线程中断则是给目标线程发送一个中断信号 如果目标线程没有接收线程中断的信号并结束线程，线程则不会终止，具体是否退出或者执行其他逻辑由目标线程决定
例1 中断失败
package com.starry.codeview.threads.P05_ThreadInterrupt;
/**
* 线程中断失败， 因为目标线程收到中断信号并没有做出处理
*/
public class T01_ThreadInterrupt_Failed {
static int i = 10;
public static void main(String[] args) {
Thread t1 = new Thread(() -> {
while (i++ < 56) {
System.out.println("t1线程执行");
Thread.yield();
}
});
t1.start();
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
t1.interrupt();
}
}例2 中断成功
package com.starry.codeview.threads.P05_ThreadInterrupt;
/**
* 线程中断成功， 目标线程收到中断信号做出了处理
*/
public class T02_ThreadInterrupt_Successed {
static int i = 10;
public static void main(String[] args) {
Thread t1 = new Thread(() -> {
while (i++ < 56) {
System.out.println("t1线程执行");
Thread.yield();
if (Thread.currentThread().isInterrupted()) {
System.out.println("t1线程被中断，退出");
return;
}
}
});
t1.start();
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
t1.interrupt();
}
}例3 Sleep中断失败
package com.starry.codeview.threads.P05_ThreadInterrupt;
/**
* 线程中断失败，Sleep遇到线程中断catch到异常会清除掉中断标记，所以线程会继续循环
*/
public class T03_ThreadInterrupt_Sleep_Failed {
static int i = 10;
public static void main(String[] args) {
Thread t1 = new Thread(() -> {
while (i++ < 56) {
System.out.println("t1线程执行");
Thread.yield();
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
System.out.println("t1线程sleep被中断");
e.printStackTrace();
}
}
});
t1.start();
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
t1.interrupt();
}
}例4 Sleep中断成功
package com.starry.codeview.threads.P05_ThreadInterrupt;
/**
* 线程中断失败，Sleep遇到线程中断catch到异常会清除掉中断标记，但是catch异常块中做出了中断处理动作，所以中断成功！！！
*/
public class T04_ThreadInterrupt_Sleep_Successed {
static int i = 10;
public static void main(String[] args) {
Thread t1 = new Thread(() -> {
while (i++ < 56) {
System.out.println("t1线程执行");
Thread.yield();
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
System.out.println("t1线程sleep被中断");
Thread.currentThread().interrupt();
}
}
});
t1.start();
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
t1.interrupt();
}
