AES encryption init error

I'm trying to set up AES encryption for an application and Eclipse is throwing the following errors:

"Multiple markers at this line
    - Syntax error on tokens, ConstructorHeaderName expected instead
    - Syntax error on token "(", < expected
    - Syntax error on tokens, ConstructorHeaderName expected instead"

on lines

enccipher.init(Cipher.ENCRYPT_MODE, secretkey);

and

deccipher.init(Cipher.DECRYPT_MODE, secretkey, new IvParameterSpec(iv));

Here is my code:

private final byte[] salt = new SecureRandom().generateSeed(8);
SecretKeyFactory fact = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
KeySpec spec = new PBEKeySpec(null, salt, 65536, 256);
SecretKey tempsecret = fact.generateSecret(spec);
private SecretKey secret = new SecretKeySpec(tempsecret.getEncoded(), "AES");

private Cipher enccipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
enccipher.init(Cipher.ENCRYPT_MODE, secret);
private final byte[] iv = enccipher.getParameters().getParameterSpec(IvParameterSpec.class).getIV();

private Cipher deccipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
deccipher.init(Cipher.DECRYPT_MODE, secret, new IvParameterSpec(iv));

protected byte[] doEncrypt(String pass){
    return enccipher.doFinal(pass.getBytes());
}
protected String doDecrypt(byte[] ciphertext) {
    return new String (deccipher.doFinal(ciphertext), "UTF8");
}

Post your code - but my guess is that you're just entering text into the class body (where it says does not go not here) instead of inside methods (where it says code goes here).

public class XYZ {

   // variable and method declarations go here  
   // code does not go here

   public XYZ () {
   // code goes here
   }
}
