Problem in copying a file in java

[Messenger]

Hello,
I'm studying Java at the moment and I would like to copy file FileCopy with (). The problem is that it makes me an error when I use it. Here is my code:

public class cpfl (
 
	
	public static void hand(String[] args) (
		
		File fl = null; File cp = null; 
		fl = new File("c:\ \test.txt "); 
		cp = new File("c:\ temp.txt ");
		
		if (fl.exists())(
			
			/ / cp.createNewFile ( );
			cp.FileCopy(myfile);
		)
		
		)
 
	)

This is not working, any help will be great. Thank you.

Check out the following code, this will help you

try (
BufferedReader buff = new BufferedReader(new FileReader("c: / test.txt")); BufferedWriter buffwrt = new BufferedWriter(new FileWriter("c: / temp.txt")); String ln;
while((ln = buff.readLine()) ! = null)(
    buffwrt.write(ln); buffwrt.NewLine();
)
buffwrt.close();
)
catch(Exception e)(
    e.printStackTrace();
)

This is the code you are looking for

try ( 
/ / Create the file: 
dst.createNewFile (); 
/ / Opening streams 
sfl = new java.io.FileInputStream (source); 
desfl = new java.io.FileOutputStream (dst); 
/ / Reading by segment 0.5Mo 
byte bf [] = new byte [512 * 1024]; 
int lec; 
while ((lec srfl.read = (bf))! = -1) ( 
desfl.write (bf, 0, lec); 
) 

/ / Copy success 
rst = true; 
) Catch (java.io.FileNotFoundException f) ( 
) Catch (java.io.IOException e) ( 
) Finally ( 
/ / Whatever happens, we close the stream 
try ( 
srfl.close (); 
) Catch (Exception e) () 
try ( 
desfl.close (); 
) Catch (Exception e) () 
) 
return (rst); 
)

The problem is that you make a copy in text mode. You must do a binary copy. Passes by simply FileInputStream and a FileOutputStream. Used an array of bytes and it will alone. I guess you are understanding what I am trying to say here.

Try the following code

String str = new String () ( 
try ( 
BufferedWriter fv = new BufferedWriter (new FileWriter ("name fv.txt")); 
flc.writeLine (str, 0, str.length ()); 
flc.close (); 
) 
catch (IOException e) ( 
System.out.println ("File error:" + e.ToString ()); 
)
