1.使用Thread.stop()？
极力不推荐此方式，此函数不安全且已废弃，具体可参考Java API文档
2.设置终止标识，例如：
import static java.lang.System.out;
public class TestThread extends Thread
{
private boolean terminationFlag;
public void run()
{
for (int i = 0; i != 10000000; ++i)
{
if (terminationFlag)
break;
out.println(i + 1);
}
}
public void terminate()
{
terminationFlag = true;
}
}
3.使用Thread.interrupt()
interrupt()函数本身并不能终止线程，需要做一些处理方可终止线程
①若线程任务中包含Object.wait()、Thread.sleep(long)等可能引发InterruptedException的函数，则在调用interrupt()后会抛出InterruptedException
import static java.lang.System.out;
import java.util.logging.Logger;
import java.util.logging.Level;
public class TestThread extends Thread
{
private static final Logger LOGGER = Logger.getLogger("TestThread");
public void run()
{
for (int i = 0; i != 10000000; ++i)
{
try
{
Thread.sleep(100);
out.println(i + 1);
}
catch (InterruptedException ex)
{
LOGGER.log(Level.SEVERE, null, ex);
break; //执行break后退出循环，run()也将执行完毕
}
}
}
}
②若线程任务中不包含可能引发InterruptedException的函数，则可将Thread.isInterrupted()的返回值作为终止标识
import static java.lang.System.out;
public class TestThread extends Thread
{
public void run()
{
for (int i = 0; i != 10000000; ++i)
{
if (isInterrupted())
break;
out.println(i + 1);
}
out.println("TestThread.run() will be finished");
}
}
