RandomAccessFile random access file can jump to anywhere in the file read and write data
RandomAccessFile (File File, String MODE)
RandomAccessFile (String name, String MODE)
MODE meanings:
"R & lt": opened in read-only
"rw": to read, write, open the
"rws": read, write, open way, "s" represents a synchronous (sync)
"RWD": read, write, open the
