线程的生命周期
线程状态的转换
通过代码输出线程的状态，代码如下
public class ThreadState_ {
public static void main(String[] args) {
T t = new T();
System.out.println(t.getName() + " 状态 " + t.getState());
t.start();
while (Thread.State.TERMINATED != t.getState()) { //当t线程的状态，不等于终止状态
System.out.println(t.getName() + " 状态 " + t.getState());
try {
Thread.sleep(500);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
System.out.println(t.getName() + " 状态 " + t.getState());
}
}
class T extends Thread {
@Override
public void run() {
while (true) {
for (int i = 0; i < 10; i++) {
System.out.println("hi" + i);
try {
Thread.sleep(1000); //休眠1秒钟
} catch (InterruptedException e) {
e.printStackTrace();
}
}
break;
}
}
}
输出状态如下
Thread-0 状态 NEW Thread-0 状态 RUNNABLE hi0 Thread-0 状态 TIMED_WAITING hi1 Thread-0 状态 TIMED_WAITING Thread-0 状态 TIMED_WAITING hi2 Thread-0 状态 TIMED_WAITING Thread-0 状态 TIMED_WAITING hi3 Thread-0 状态 TIMED_WAITING Thread-0 状态 TIMED_WAITING hi4 Thread-0 状态 TIMED_WAITING Thread-0 状态 TIMED_WAITING hi5 Thread-0 状态 TIMED_WAITING Thread-0 状态 TIMED_WAITING hi6 Thread-0 状态 TIMED_WAITING Thread-0 状态 TIMED_WAITING hi7 Thread-0 状态 TIMED_WAITING Thread-0 状态 TIMED_WAITING hi8 Thread-0 状态 TIMED_WAITING Thread-0 状态 TIMED_WAITING hi9 Thread-0 状态 TIMED_WAITING Thread-0 状态 TIMED_WAITING Thread-0 状态 TERMINATED
