<分区>
总的来说，我无法理解线程。就我而言， 使用 Java 和 Android。
假设我有一个名为 A 的线程，它启动线程 B。如果线程 A 停止，则线程 B 将继续存在。这怎么可能？谁现在属于线程 B？到主线程？
线程类
public class ParentThread extends Thread {
public void run(){
Log.e("PARENT THREAD", "STARTS RUNNING");
new Thread(new Runnable() {
@Override
public void run() {
while (true) {
Log.e("CHILD THREAD", "IS ALIVE");
try {
Thread.sleep(1000);
}
catch (InterruptedException exc) {
e.printStackTrace();
}
}
}
}).start();
Log.e("PARENT THREAD", "STOPS RUNNING");
}
}
Activity
new ParentThread().start();
Logcat 输出
