The instance describes Java IO file replication, and the instance describes javaio IO streams are mainly divided into two categories: byte streams and byte streams. Note: 1. audio files, images, and videos (with a wide range) are throttled by words 2. if it involves only the text, the ghost stream is used. Use byte str

The use of the file class in the JAVAI/O section of the Java---(note)In Java, I/O (input/output) is a tedious thing, because I do not see the obvious effect, but the input/output is a necessary part of all programs-using the input mechanism, allowing the program to read external data (including data from disk, CD and other storage devices), user input data, using
