Examples of java.io.FileInputStream

java.io.FileInputStream
A FileInputStream obtains input bytes from a file in a file system. What files are available depends on the host environment.
FileInputStream is meant for reading streams of raw bytes such as image data. For reading streams of characters, consider using FileReader. @author Arthur van Hoff @version 1.68, 04/07/06 @see java.io.File @see java.io.FileDescriptor @see java.io.FileOutputStream @since JDK1.0
