I'm just playing around with some code and I can't figure out why this isn't working. It's only "encrypting" one word. Can anyone tell me what's wrong with it?
import java.util.*;
public class EncrypterDriver {
static String encrypt(String fileMessage)
{
String encryptedMessage = "";
char fileChar = '0';
String fileWord = "";
String encryptedWord;
StringTokenizer st = new StringTokenizer(fileMessage);
while(st.hasMoreTokens()) //While the fileMessage string has more words in it
{
fileWord = st.nextToken(); //Returns word from the fileMessage string and stores it in fileWord
System.out.println(fileWord);
encryptedWord = ""; //Resets encrypted word
for(int i = 0; i < fileWord.length() - 1; i++) //loops through each character in the fileWord string
{
fileChar = fileWord.charAt(i); // returns the character at position "i" from the string fileWord
fileChar+= 10; // adds 10 to the character
encryptedWord += fileChar; // puts the character in the String encryptedMessage
}
encryptedMessage += encryptedWord + " "; //stores a word in encrypted word and inserts a space after every word encrypted
}
return encryptedMessage;
}
public static void main(String[] args) {
String message = "";
String encryptedMessage = "";
Scanner sc = new Scanner(System.in);
System.out.println("Enter a message: ");
message = sc.next();
encryptedMessage = encrypt(message);
System.out.println(encryptedMessage);
}
}
