Exception java.io.BufferedInputStream java code examples | Codota A BufferedInputStream adds functionality to another input stream-namely, the ability to buffer the input and to support the mark and reset methods. When the BufferedInputStream is created, an internal buffer array is created. As bytes from the stream are read or skipped, the internal buffer is refilled as necessary from the contained input stream, many bytes at a time. How to read file in Java – BufferedInputStream 2) Passed the file instance to the FileInputStream which opens a connection to the actual file, the file named by the File object file in the file system. 3) Passed the FileInputStream instance to BufferedInputStream which creates a BufferedInputStream and saves its argument, the input stream in, for later use. An internal buffer array is
I was trying to read a file into an array by using FileInputStream, and an ~800KB file took about 3 seconds to read into memory. I then tried the same code except with the FileInputStream wrapped into a BufferedInputStream and it took about 76 milliseconds.
