The Java Employment Training course is my first book to learn Java in college, and it is also a textbook for my specialized courses in college. As a result of this experience, I have a special affection for this book, especially to hear the author of the book Zhang Xiaoxiang teacher Accidental death of the news, shocked me for a long time. After graduating for three years, I have read this book two times, a

1. OverviewBefore generics were introduced, Java types were divided into primitive types, complex types, where complex types were divided into arrays and classes. After introducing the paradigm, a complex typeIt can be broken down into more types.For example, the original type List, which is now subdivided into listNote that now ListThere is no inheritance between them, even if string inherits object. The following code is illegallistlistThe reason fo

In the previous section ("Java NIO Framework Netty Tutorial (12) Concurrent access Test (middle)"), we tested the Netty concurrency scenarios from all angles. In this section, we will focus on the last issue mentioned in the previous section. In the case of multi-threaded concurrent access, there will beWarning: EXCEPTION, implement One.coder.netty.chapter.eight.ObjectClientHandler.exceptionCaught () for pr

The problemJJTree is a part of JavaCC are a parser/scanner generator for Java. JJTree is a preprocessor for JavaCC this inserts parse tree building actions at various places in the JavaCC source. To follow along your need to understand the core concepts of parsing. Also Review basic JJTree documentation and samples provided in JavaCC distribution (version 4.0).JJTree is magically powerful, but it's as complex. We used it quite successfully at my start

Java annotations provide information about the code and have no direct impact on the annotated code structure. In this tutorial, we'll learn about Java annotations, how to write custom annotations, how annotations are used, and how to use reflection to parse annotations.Annotations are introduced in Java 1.5 and are no

. Media mapping When a static resource is requested, Tomcat automatically adds a Content-type header based on the suffix name to map the media type.The Tomcat built-in contains many mapping configurations, which are appended in Web. XML if required.Note: If the custom code download file must be added in response to the Content-type header. 10.jsp Configuration The Jsp-config element is primarily used to set the relevant configuration of the JSP, 11.

= bytebuffer.allocate (1024x768);//write data into buffersbytebuffer[] Bufferarray = {header, body};chan Nel.write (Bufferarray);The buffers array is the entry for the Write () method, and the write () method writes data to the channel in the order in which buffer is in the array, noting that only data between position and limit is written. Therefore, if a buffer has a capacity of 128byte, but contains only 58byte of data, then this 58byte of data will be written to the channel. Therefore, co

Java NiO channels are similar to streams, but are somewhat different: The data can be read from the channel, and the data can be written to the channel. But stream reads and writes are usually one-way. Channels can be read and written asynchronously. The data in the channel is always read to a buffer first, or it is always written from a buffer. As mentioned above, the data is read from the channel to the buffer, and the data is
