In File Reading and network data processing, the format conversion between Byte and String is often performed. Byte [] Byte Transfer to String object: Fin = mContext. openFileInput ("helloworld.txt "); Int size = fin. available (); Byte [] buffer = new

Byte array and String Conversion in java, bytestring // String to byte [] String str = "problem"; byte [] srtbyte = str. getBytes (); // byte [] to stringString res = new String (srtbyte); System. out. println (res );You can also set the encoding method. String str = "

use the MemoryStream object, which uses memory as a fallback memory (more efficient than performing file I/O, using memory; file i/ O execution speed is relatively slow).Image.Save methodImage.Save method (Stream, ImageFormat)This method saves the image to the specified stream in the specified format. The image must be saved in a zero offset stream. If any additional data has been written to the stream before the image is saved, the image data in the stream is corrupted.ResourcesStream Flow cla

In opencv, mat is a multi-dimensional dense data array. It can be used to process common multidimensional data such as vectors and matrices, images, and histograms. Mat has three important methods: 1. Mat MAT = imread (const string * filename); read the image 2. imshow (const string framename, input

Our machine can only read bytecode, but it is difficult for us to read bytecode. Therefore, encoding and decoding are required when people communicate with the machine. InputStreamReader and its subclass FileReader: (from byte to character) is a decoding process; OutputStreamWrite and its subclass FileWriter: (from character to byte) is a encoding process. In the decoding process of InputStreamReader, the m
