Java 学习笔记之 Sleep停止线程
2024-09-01 10:33:13
Sleep停止线程:
在Sleep状态下被interrupt，interrupted 状态会被擦除，返回false。
线程在Sleep状态下被interrupt：
public class SleepInterruptThread extends Thread{
@Override
public void run() {
try {
System.out.println("run begin");
Thread.sleep(2000000);
System.out.println("run end");
} catch (InterruptedException e) {
System.out.println("Interrupt in sleep stage. Interrupted status: " + this.isInterrupted());
e.printStackTrace();
}
}
}
public class ThreadRunMain {
public static void main(String[] args) {
testSleepInterruptThread();
}
public static void testSleepInterruptThread(){
try {
SleepInterruptThread sit = new SleepInterruptThread();
sit.start();
Thread.sleep(1000);
sit.interrupt();
} catch (InterruptedException e) {
System.out.println("Main catch");
e.printStackTrace();
}
System.out.println("end!");
}
}
运行结果：
线程在Sleep之前被interrupt：
public class BeforeSleepInterruptThread extends Thread{
@Override
public void run() {
try {
for (int i=0;i<100000;i++){
System.out.println("i="+(i+1));
}
System.out.println("run begin");
Thread.sleep(2000000);
System.out.println("run end");
} catch (InterruptedException e) {
System.out.println("First interrupt, then sleep. Interrupted status: " + this.isInterrupted());
System.out.println("First interrupt, then sleep. Interrupted status: " + Thread.interrupted());
e.printStackTrace();
}
}
}
public class ThreadRunMain {
public static void main(String[] args) {
testBeforeSleepInterruptThread();
}
public static void testBeforeSleepInterruptThread(){
try {
BeforeSleepInterruptThread bsit = new BeforeSleepInterruptThread();
bsit.start();
Thread.sleep(100);
bsit.interrupt();
System.out.println("end!");
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
