; }This is mistaken: read a paragraph first, write a paragraph, then change the offset, and then use the new offset to read a paragraph, write a paragraph, until the file read and write finished. But this is wrong, because after using BUFFEREDXXX, the process has been implemented. The offset in read (byte[] b, int offset, int length) actually refers to

path, but pass a OutputStream object?A: The reason is simple, the byte buffer stream only provides buffers, designed for efficiency. However, the actual read and write operation is also dependent on the basic flow object implementation.3. Bufferedoutputstream Write Data , code example:1 Packagecn.itcast_05;2 3 ImportJava.io.BufferedOutputStream;4 ImportJava.io.FileOutputStream;5 Importjava.io.IOException;

CGI has a 500 error because the HTTP header is notGI communication relies on stdout to communicate with the browser.So simply write inside the py-cgi-index.py:#!/usr/bin/env pythonprint ' Hello World 'It is wrong to write like this.The CGI interface specifies that the CGI script output should begin with an HTTP header.The character "Hello World" cannot be identified as any valid HTTP header,Therefore, if yo

Read file:is the process by which HDFs reads files:Here is a detailed explanation:1. When the client begins to read a file, the client first obtains the Datanode information for the first few blocks of the file from Namenode. (steps)2. Start calling read (), the Read () method, first to read the first time from the Namenode to obtain a few blocks, when the read is completed, then go to Namenode take a block of datanode information. (Step 3,4,5)3. Call the Close method to complete the read. (Step

Description (2017-7-31-16:25:06):1. There are two ways, the first is to create a txt with FileStream, write data with StreamWriter, the period also to add judgment, whether the existence of this TXT file, if not exist on the creation, there is an append write. It's too much trouble!2. The second type is direct File.appendalltext (string path, string contents), the first parameter is the TXT path + file name

decomposition point of the integer data and the floating-point data. Using the method of demarcation we actually completed the split conversion process of string-to-integer object and floating-point object.The use of the STR () member function allows the Istringstream object to return a string string, such as the output operation in this example (Cout2, the use of OstringstreamOstringstream is also constructed from a string object, and the Ostringstream class inserts a character into a string.T
