abstract class, which is a superclass of all classes that represent the byte input stream. , the basic common function method of byte input stream is defined. int Read (): reads a byte and returns, no bytes returned -1. int Read (byte[]): reads a certain amount of bytes and stores it in a byte array, returning the number of bytes read to, no bytes returned -1. FileInputStream classTo read a file from an input stream 1. Create a subclass object for the byte input stre

system classes)Our program turns out this way:I added a method to read the file in Myutil, which is defined as follows:public static string Getfilecontent (String fileName)He can read the files in the current directory and return the contents of the file based on the file name passed in.We don't care about the implementation, we just need to call it. The Myutil code is as follows:1 Packageutil;2 3 ImportJava.io.*;4 5 Public classMyutil {6 7 Public Static voidprintln (String message)

Vue JS file and then use the Vue object to initialize the application on the line, very simple. But without the build process, it means that we need to write the Vue component with a hard-to-read string template or a more difficult-to-read render function, rather than writing it like Webpack 单文件组件 .This is obviously not tolerated. Written or read Webpack loader students should be clear, loader is actually a function of string processing, not what black technology, the reason Webpack added Vue-l

number of IO to the hard disk access, protect our hard disk. The buffer can be imagined as a small bucket, the data to be read and written into the water, each time the data read or write data before the data is loaded into the bucket, filled with the later to do processing. This is called a buffer. First put the data into the buffer, wait until the buffer is full, once again the buffer in the data written to the hard disk or read out, this can effectively reduce the number of access to the har

Here we'll derive json from the JavaScript syntax, and on that basis, how to use JSON on an AJAX application. In JavaScript everybody knows there's a arrays: an array. Its format is as follows: Copy Code code as follows: var Beatles = ["Paul", "John", "George", "Ringo"]; The example above is the form of an array and the following equivalence: Copy Code code as follows: var Beatles =new Array ["Paul", "John", "George", "Ringo"]; One more is objects, a

The last 2 months have been doing mobile phone and TV development, the development process encountered a variety of pits. Get fast New Year's day, finally put on the line. 2 months to dry down full of hard work, not so busy with their own preparation of the front-end performance tuning summary below, in order to facilitate the use of their own once again to be handy. Referring to the high-performance website Construction Guide-the essence of front-end engineer skills, this paper mainly summarize
