Design a program (copy. Java) to replicate files

Design 1Program(Copy. Java), which allows you to copy files.

 

Requirements:Simulate the Copy command of Dos. Input two path names to copy the file. If you enter the following command Java copy F: \ 1.txt F :\\ 2.txt, the contents of F :\\ 1.txt will be copied to f :\\ 2.txt.

Tip:You can use file, fileinputstream, and fileoutputstream.

 

 Package  Com. CMM. io4;  Import Java. Io .* ;  Public   Class  Copy {  /**  *  @ Param Arg * @ Peter Cao  */      Public   Static   Void  Main (string [] ARGs ){  //  Todo auto-generated method stub String filepath1 = "" ; String filepath2 = "" ; File file1 = Null  ; File file2 = Null  ; Byte [] Bt = New   Byte [1024 ];  If (ARGs. Length = 2 ) {Filepath1 = ARGs [0 ]; Filepath2 = ARGs [1 ]; File1 = New  File (filepath1); file2 = New  File (filepath2 ); If (File1.exists ()&& File1.isfile ()){  Try  {  //  Fileinputstream -- bufferedinputstream Fileinputstream fins = New  Fileinputstream (file1); bufferedinputstream bins = New  Bufferedinputstream (FINS );  // Bufferedinputstream bins = new bufferedinputstream (New fileinputstream (file1 ));  //  Fileoutputstream -- bufferedoutputstream Fileoutputstream Fouts = New  Fileoutputstream (file2); bufferedoutputstream bouts = New  Bufferedoutputstream (Fouts );  If (! File2.exists () {file2.createnewfile (); //  If the file does not exist, create the file.  }  While (Bins. Read (BT)> 0) //  Or bins. Read (BT )! =-1  {Bouts. Write (BT); bouts. Flush (); BT = New   Byte [1024]; //  Refresh byte [] } Bouts. Close (); Fouts. Close (); bins. Close (); fins. Close ();}  Catch  (Exception e) {e. printstacktrace ();}}}}}
