New Features of JDK 8-Lambda expressions and new features of JDK 8 lambda JDK 8 has been released for nearly four years. It seems a little out of date to talk about its new features ". Although JDK8 is no longer "new", Lambda expressions, one of its important features, are still not used by most developers or even well-known. As we all know in the development env

Java 8 only needs one line of code to read files-Beijing shangxue and Java 8 Java 8 only needs one line of code to read a file This method ensures that the file attribute is disabled when all the bytes of the file are read. Otherwise, an IO exception or other unchecked exceptions will occur. This means that you do not need to close the file after reading the last

Transferred from: https://www.cnblogs.com/kclteam/p/5278926.htmlThe new project, presumably the situation is this: there may be many countries, different language users, the analogy of Chinese, traditional Chinese, Korean, Japanese and so on, the development of the choice of UTF-8 coding, development smooth, no problem. Yesterday did a CSV export function, the export of something completely chaotic:Set mb_convert_encoding ($content, "gb2312", "UTF-

Bom--byte order mark, is the byte sequence mark In the UCS code there is a character called ZERO WIDTH No-break Space, and its encoding is Feff. Fffe is not present in UCS, so it should not appear in the actual transmission. UCS specification recommended that we transfer the byte stream before the transmission of the character "ZERO WIDTH no-break space." This means that if the recipient receives the Feff, the byte stream is Big-endian, and if Fffe is received, it indicates that the byte strea

If you want to experience Windows 8 consumer Preview (Beta), you can use the following methods: Through Virtualization (hyper-V), the premise is that I must have installed Windows Server 2008 Format the C drive and reinstall the system (the cost is huge) For dual-system installation, you have to create a new partition to install Win8. Start from vhd (virtual hard disk) "Starting from vhd" is the best way for me to experience Win

I am searching for it today. Program During UTF-8 correction, garbled characters are found in the generated UTF-8 format document. The original file Create_html.aspCodeAs follows: Copy code The Code is as follows: Set objrs = server. Createobject ("scripting. FileSystemObject ") Conn = server. mappath ("example. xml ") Set stream = objrs. opentextfile (Conn, 1, true,-2) Content = stream. readall Resp

As UTF-8 is a 8-bit encoding no BOM is required and Anyu+feff character in the decoded Unicode string (even if it ' s the F Irstcharacter) is treated as a ZERO WIDTH no-break SPACE.UTF-8 is encoded in bytes, its byte order is 様 in all systems, there is no byte order problem, and therefore it does not actually require a BOM ("Byteorder Mark"). But UTF-

New Features of Java 8: Default interface methods and static interface methods, new features of Java 8Interface Definition The function of an interface is to define the functions required by an instance of this type, that is, the tasks that must be executed, and you do not need to care about how these tasks are implemented. The method defined by the interface does not have a method body, and the interface cannot define instance variables. If a class i

Fallacy 8: The network configuration is similar.Mobile devices are always unexpected, relative to web openness. For an application, it is possible that most users are in a similar network configuration. Unfortunately, this assumption can lead to some problems in some cases.Similar to fallacy 6, not all networks have the same configuration. For example, some WiFi networks allow point-to-point communication between devices, some of which are not support
