(JavaNIO (Chinese version), bought with money on Taobao, share it, and hope it will be helpful to everyone. JavaNIO explores the new I/O features of version 1.4 in depth, and tells you how to use these features to greatly improve the performance of Java code you write. This booklet discusses in detail the typical I/O problems faced by programmers, and explains how to make full use of the potential provided by the new I/O features. You will learn how to use these tools to manage the I/O problems often encountered in the actual office through examples, and understand how these new features have a direct impact on response rate, scalability and reliability. The NIOAPI is a supplement to, rather than a replacement for, the 1.3 I/O feature. Therefore, when to use the new API and when the old 1.3 I/OAPI is more suitable for specific use are also what you will learn.
