Threading and synchronization are the core features of the Java programming language, which are described in the Java Language Specification (JLS). RTSJ extends the core functions of JLS in a variety of ways. (See Resources for links to JLS and RTSJ.

Garbage collection, like a double backgammon, takes only a few minutes to learn, but it takes a lifetime to master. Ben Evans, a senior trainer and advisor, discussed garbage collection from a basic perspective in the presentation of visual garbage

Before we talked about thread creation, that was the first step in the thread lifecycle, followed by starting thread with the start () method, which performs some internal administrative work and then invokes the thread's run () method, where the

Fail-fast Summary (through ArrayList to explain the fail-fast principle, solution) In front, we have learned the ArrayList. Next, we take ArrayList as an example to understand the fail-fast mechanism of iterator. 1 Fail-fast Profile The fail-fast

In fact, this study summary should be written early, but the technical blog does not grasp the place, always feel that the language is not vivid enough, expression also slightly far-fetched, in addition to paste a few lines of code, the middle of

As early as the summary, I will try to put the focus of the synchronized is simple: it is matching and object of the implicit lock use, attention must be the object of the implicit lock! So how does the following example explain this? Java code /**

There are two types of annotations in Java. The first is a traditional, C-style annotation, inherited from C + +. These comments start with a "/*", followed by a comment, and can span multiple lines, ending with a "* *". Note that many programmers

In many cases, there may be multiple threads that require access to a small number of resources. It is assumed that several threads are running on the server that answer client requests. These threads need to connect to the same database, but at any
