Java读存大块二进制资料文件，java.io 包中提供了BufferedInputStream 和BufferedOutputStream 类来缓存的读写流。但是读写大块的数据文件时，使用这两个类的效果并不是很好。本例演示了如何自定义缓存区，并使用不具有缓冲功能的DataInputStream 和DataOutputStream 类来读写大块的数据文件。效果如图所示，当按下“Start”按钮后，程序从源文件“d:\image.jpg”读取指定大小（缓冲区的大小）的数据放入缓冲区，然后将缓存区的数据写入目标文件“d:\a.jpg”，如此反复直到读完源文件。-Java read binary data files stored chunks, java.io package provides a BufferedInputStream and BufferedOutputStream classes to read and write cache flow. However, when reading and writing large data files, use these two classes of effect is not very good. This example demonstrates how to customize the cache and use DataInputStream and DataOutputStream class does not have the buffering functions to read and write chunks of data files. Results as shown, when you press "Start" button, the program from the source file "d: \ image.jpg" reads the specified size (buffer size) of data into a buffer, then the data cache written to the destination file "d: \ a.jpg", and so forth until you read the source file.
