Java IO buffer Copy file

Directly write the code of the class and the package itself import create, hand hit very tired

public static void Main (String args[]) {

FileReader Fr=null; File input stream

FileWriter Fw=null; File output stream

BufferedReader Br=null; Character buffer input stream

BufferedWriter Bw=null; Character Buffer output stream

try{

File F = new file ("F:\\ha.txt");

Fr =new FileReader (f); Read the file F

File s =new file ("F:\\haha.txt"); Copy the generated file name

FW =new FileWriter (s); Write to S.

BR =new BufferedReader (FR); Buffer Storage FR Content

BW = new BufferedWriter (FW); Contents of buffer Memory write FW

Char c [] =new char[(int) (F.length ())]; The length of the character C is the length of the F file

int Len=br.read (c); Define an intermediate variable to accept C

Bw.writer (C,0,len);

System.out.print (New String (C,0,len)); Need to be aware of type conversions

}catch (FileNotFoundException e) {

E.printstacktrace ();

}catch (IOException e) {

E.printstacktrace ();

}finally{

try{

Br.close ();

Bw.close ();

}catch (IOException e) {

E.printstacktrace ();

}

}

}
