This article mainly introduces the relevant knowledge of the multi-thread synchronization class CountDownLatch in Java, which has a good reference value. Let's take a look at it with the editor. In multi-thread development, we often encounter operations that we hope will happen after a group of threads are completed. Java provides a multi-thread synchronization auxiliary class that can fulfill such needs: Common in the class Method: The construction method: CountDownLatch(int count) The parameter count is a counter, which is generally assigned with the number of threads to be executed. long getCount(): Get the current counter value. void countDown(): When the counter value is greater than zero, the method is called and the counter value is reduced by 1. When the counter reaches zero, all threads are released. void await(): Call this method to block the current main thread until the counter decreases to zero. Code example: Thread class: import java.util.concurrent.CountDownLatch; public class TestThr
