Hello,
When I am reading a file and printing the contents, it is displaying in some format with control characters (some boxes). I don't know which format it is. I need to convert it into string -- i have replace few values with others according to business logic which is not happening now. Please help.
Code is as below. The source file is in binary/byte format i guess..
public void copyFiles(File src, File dest) throws IOException {
// Check to ensure that the source is valid...
System.out.println("##### Called Copy Files #######");
//if (dest.exists()) { JOptionPane.showMessageDialog(null, "Destination already exists"); }
if (!src.exists()) {
throw new IOException("copyFiles: Can not find source: "
+ src.getAbsolutePath() + ".");
} else if (!src.canRead()) { // check to ensure we have rights to the
// source...
throw new IOException("copyFiles: No right to source: "
+ src.getAbsolutePath() + ".");
}
// is this a directory copy?
if (src.isDirectory()) {
if (!dest.exists()) { // does the destination already exist?
// if not we need to make it exist if possible (note this is
// mkdirs not mkdir)
if (!dest.mkdirs()) {
throw new IOException(
"copyFiles: Could not create direcotry: "
+ dest.getAbsolutePath() + ".");
}
}
// get a listing of files...
String list[] = src.list();
// copy all the files in the list.
for (int i = 0; i < list.length; i++) {
File dest1 = new File(dest, list[i]);
File src1 = new File(src, list[i]);
copyFiles(src1, dest1);
}
} else {
// This was not a directory, so lets just copy the file
FileInputStream fin = null;
FileOutputStream fout = null;
byte[] buffer = new byte[4096]; // Buffer 4K at a time (you can
// change this).
int bytesRead;
try {
// open the files for input and output
fin = new FileInputStream(src);
fout = new FileOutputStream(dest);
// while bytesRead indicates a successful read, lets write...
while ((bytesRead = fin.read(buffer)) >= 0) {
System.out.println("buffer :"+buffer);
String value = new String(buffer);
System.out.println("New buffer :"+value);
//byte[] encoded = Base64.encodeBase64(buffer);
String printMe = new String(buffer, "ASCII");
System.out.println("Latest buffer :"+printMe);
fout.write(buffer, 0, bytesRead);
}
} catch (IOException e) { // Error copying file...
IOException wrapper = new IOException(
"copyFiles: Unable to copy file: "
+ src.getAbsolutePath() + "to"
+ dest.getAbsolutePath() + ".");
wrapper.initCause(e);
wrapper.setStackTrace(e.getStackTrace());
throw wrapper;
} finally { // Ensure that the files are closed (if they were open).
if (fin != null) {
fin.close();
}
if (fout != null) {
fout.close();
}
}
}
}
