Java线程组getMaxPriority()方法
ThreadGroup类的
getMaxPriority()方法返回线程组的最大优先级。
语法:
public final int getMaxPriority()
返回:
此方法返回线程组中的线程可以具有的最大优先级
示例
class NewThread extends Thread
{
NewThread(String threadname, ThreadGroup tg)
{
super(tg, threadname);
}
public void run()
{
for(int i = 0;i < 10;i++)
{
i++;
}
System.out.println(Thread.currentThread().getName() + " completed executing");
}
}
public class ThreadGroupGetPriorityExp
{
public static void main(String arg[]) throws InterruptedException,
SecurityException, Exception
{
// creating a parent threadGroup
ThreadGroup tg1 = new ThreadGroup("Parent thread");
// returns the maximum priority of parent thread
System.out.println("Maximum priority of Parent threadGroup: " + tg1.getMaxPriority());
// creating a child threadGroup
ThreadGroup tg2 = new ThreadGroup(tg1, "Child thread");
// returns the maximum priority of child thread
System.out.println("Maximum priority of Child threadGroup: " + tg1.getMaxPriority());
// creating a thread
NewThread t1 = new NewThread("Thread-1", tg1);
t1.start();
// creating another thread
NewThread t2 = new NewThread("Thread-2", tg2);
t2.start();
}
}
输出:
Maximum priority of Parent threadGroup: 10
Maximum priority of Child threadGroup: 10
Thread-1 completed executing
Thread-2 completed executing
