threadb resources, threadb waiting for Threada resources (here because of the synchronization method used, So the resource exactly refers to the object-level lock of the D1 and D2, which causes the deadlock. While there is no good way to avoid deadlocks in Java, it is useful to follow some rules in programming to minimize the occurrence of deadlocks: minimizing the scope of the lock, such as using a synchr

Reference Java Programming Tutorial (second Edition) Yong Junhai's book 12 chapters The establishment of a server-side program design model usually consists of the following five steps: (1) On the server side, first create the ServerSocket instance object, register the port number to connect on the server side, and the maximum number of clients allowed to connect. (2) Call the ServerSocket member method acc

In Java network programming let us get a network address resources, we often use the URL Uniform Resource Locator (uniform Resource Locator), URL class Java.net.URL. The URL is defined as follows: [Scheme :] scheme-specific-part[ # Fragment] where the square brackets [...] are used to describe optional components, characters : and # represent themselves. View the API for more information. A, URL The main

We often encounter three problems in concurrent programming: atomicity, Visibility, and order, and here are a few three questions to analyze. If there are any mistakes, please criticize and correct them. first, the atomic nature Atomic lines: One or more operations as a whole, either all executed or not executed, and the operation is not interrupted by the thread scheduling mechanism during execution, and once the operation has started, it runs to the
