Hi Friend,

Try the following code:

import java.io.*;
import java.util.*;

public class CopyFile{
private static void copyfile(String srFile, String dtFile){
try{
File f1 = new File(srFile);
File f2 = new File(dtFile);
InputStream in = new FileInputStream(f1);
OutputStream out = new FileOutputStream(f2,true);
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0){
out.write(buf, 0, len);
}
in.close();
out.close();
System.out.println("File copied.");
}
catch(Exception ex){
System.out.println(ex);
}
}
public static void main(String[] args){
Scanner input=new Scanner(System.in);
System.out.println("Source File");
String f1=input.next();
System.out.println("Destination File");
String f2=input.next();
copyfile(f1,f2);
}
}

Thanks
