Hello,
I have written some code to encrypt the contents of a textfile by using the method Character.reverseBytes as shown below:
try {
reader = new BufferedReader(new FileReader(file));
writer = new BufferedWriter(new FileWriter(outfile));
String text = "";
// repeat until all lines are read
while ((text = reader.readLine()) != null) {
String reverseText = "";
for (int i=0; i<text.length(); i++) {
reverseText += Character.reverseBytes(text.charAt(i));
}
writer.append(reverseText + "\n");
}Then I use the same method to decrypt the contents of the encrypted textfile.
The thing is that when I execute this code from NetBeans, it can encrypt and decrypt the file fine.
However if I execute the java code from my computer as standalone program, encrypting returns a textfile full of "?" sings. And then when I try to decrypt it, I still get the same "?" signs.
Why is that?
Can you help?
Thank you very much for your valuable time.
