设置Java线程的优先级 [英] Setting priority to Java's threads

问题描述

我有一个在几个线程中运行的程序。主线程与其他线程共享一个对象，在main中我有一个调用：

I have a program that runs in a few threads. The main thread shares an object with the other threads and in the main I have a call to:

synchronized(obj){
    do stuff
}

我怀疑主要线程是饥饿的无法访问 obj 。如何提高主线程的优先级或默认情况下它是否已高于其他线程？

I have a suspicion that the main thread is starved and isn't getting access to obj. How do I raise the priority of the main thread or is it already higher than the other threads by default?

推荐答案

你有一个Thread类中的setPriority（）方法。

You have a setPriority() method in the Thread class.

检查这个javadoc 。

将线程优先级设置为最大值：

Setting thread priority to maximum:

public static void main(String args[]) {
    Thread.currentThread().setPriority(Thread.MAX_PRIORITY);
    // Your main code.
}
