Converting A SecretKey To String And Back Again

I'm using the class below to encrypt and decrypt data in my program. It works rather well with the exception that I can't for the mind of me get the recreation of the key to work. When the program runs the first time, it creates a key and saves it to Data.txt. This part works fine, and there are no errors, the encryption and decryption works until I reload the program and it tries to recreate the key using the String in the .txt.

read = loadFile.readline();
byte[] data = read.getBytes("UTF-8");
key = new SecretKeySpec(data, 0, data.length, "PBEWithMD5AndDES");

I've looked at:
java - convert Byte Array to Secret Key - Stack Overflow
java - Converted secret key into bytes, how to convert it back to secrect key? - Stack Overflow

and a number of other sites which didn't work, both of these however suggested the key = new SecretKeySpec. The actual key became: "[B@79fe3f51". Whereas the recreated key became: "[B@3e1d1648".So they are close, but not the same.I create the original key like this:

key = SecretKeyFactory.getInstance("PBEWithMD5AndDES").generateSecret(keySpec);

Encryption.java:

public class Encryption { 
public Cipher dcipher, ecipher; 
// Responsible for setting, initializing this object's encrypter and
// decrypter Chipher instances
Encryption(String passPhrase) {
