Java实例-查看线程优先级

Java实例-查看线程优先级

Java 实例

以下实例演示了如何使用 getThreadId() 方法获取线程id：

Main.java 文件

public class Main extends Object {
private static Runnable makeRunnable() {
Runnable r = new Runnable() {
public void run() {
for (int i = 0; i < 5; i++) {
Thread t = Thread.currentThread();
System.out.println("in run() - priority="
+ t.getPriority()+ ", name=" + t.getName());
try {
Thread.sleep(2000);
}
catch (InterruptedException x) {
}
}
}
};
return r;
}
public static void main(String[] args) {
System.out.println("in main() - Thread.currentThread().getPriority()=" + Thread.currentThread().getPriority());
System.out.println("in main() - Thread.currentThread().getName()="+ Thread.currentThread().getName());
Thread threadA = new Thread(makeRunnable(), "threadA");
threadA.start();
try {
Thread.sleep(3000);
}
catch (InterruptedException x) {
}
System.out.println("in main() - threadA.getPriority()="+ threadA.getPriority());
}
}

以上代码运行输出结果为：

in main() - Thread.currentThread().getPriority()=5
in main() - Thread.currentThread().getName()=main
in run() - priority=5, name=threadA
in run() - priority=5, name=threadA
in main() - threadA.getPriority()=5
in run() - priority=5, name=threadA
in run() - priority=5, name=threadA
in run() - priority=5, name=threadA
