IO of the byte stream and character stream

IO of the byte stream and character stream
byte stream and character stream have mythical difference does it make?
Any data byte streaming image video text, etc.
The character stream can only handle plain text (plain text is also recommended when using a character stream)

The computer is the same Oh, so do not flow processing non-character file with the characters.
Because this is only the first IO of the opening so briefly

Byte stream

package IO;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
//1  选择源 
//2 选择流
//3 操作 
// 4 释放资源
public class 标准版文件字节流 {
public static void main(String[] args) {
	标准版文件字节流 f= new 标准版文件字节流();
	f.out();
}
