NIO（New I/O）是Java中一种提供了非阻塞式I/O操作的编程模型。它引入了一组新的Java类，用于取代传统的Java I/O类（如InputStream和OutputStream），以提供更高效、更灵活的I/O操作。// 部分NIO API实际上是阻塞的，例如File APIJava NIO允许执行非阻塞的IO。例如，线程可以 ...

2022年8月15日 · Java NIO是Java1.4之后推出来的一套IO接口，NIO提供了一种完全不同的操作方式， NIO支持面向缓冲区的、基于通道的IO操作。 新增了许多用于处理输入输出的类，这些类都被放在java.nio包及子包下，并且对原java.io包中的很多类进行改写，新增了满足NIO的功能。

2024年6月12日 · 本文介绍了Java NIO（New IO）及其主要组件，包括Channel、Buffer和Selector，并对比了NIO与传统IO的优势。 文章详细讲解了FileChannel、SocketChannel、ServerSocketChannel、DatagramChannel及Pipe.SinkChannel和Pipe.SourceChannel等Channel实现类，并提供了示例代码。

7 小时之前 · Reuters reported, citing four people familiar with the matter, that CATL is in talks to buy a controlling stake in Nio's power unit, which runs over 3,000 battery swapping stations in China.. The sources did not divulge how much CATL offered as part of the proposal. However, one of the sources told Reuters that Nio Power was valued at over RMB 10 billion ($1.37 billion) during a fundraising ...

2022年8月11日 · On August 4th, J.D. Power held a virtual award ceremony. NIO won three major recognitions at the event: NIO ES8 won first place in the 2022 China New Energy Vehicle Automotive Performance Execution and Layout (NEV-APEAL)*. This is the NIO ES8’s 2nd win since J.D. Power China NEV-APEAL was released in 2021.

The java.nio package defines the buffer classes, which are used throughout the NIO APIs. The charset API is defined in the java.nio.charset package, and the channel and selector APIs are defined in the java.nio.channels package.

2024年8月30日 · Nio topped the J.D. Power 2024 China New Energy Vehicle Customer Experience Value Index (NEV-CXVI) Study, which was released on August 29. In a vindication for the approach of the Chinese EV startups both Li Auto and Xpeng also scored highly. Reportedly, it is the sixth consecutive year that NIO has topped the chart.

Java I/O support is included in the java.io and java.nio packages. Together these packages include the following features: Input and output through data streams, serialization and the file system. Charsets, decoders, and encoders, for translating between bytes and Unicode characters. Access to file, file attributes and file systems.

19 小时之前 · A deeper HOMO energy level was found for cp/np-NiO x compared to cp-NiO x. The space-charge limited current (SCLC) method estimated a higher trap-state density in cp-NiO x than in cp/np-NiO x . The studies of light intensity-dependent open-circuit voltage ( V OC ) and short-circuit current density ( J SC ) revealed a less charge recombination ...
