Java compilation errors on lines starting with *

Question

I am fairly new to Java and attempting to use the Java Crypto extension, so far I have this, except Eclipse is throwing errors on the lines with the * and I'm not sure why. I added in the *... they are not in the code normally.

private static byte[] getKey(byte[] paramArrayOfByte)

    throws NoSuchAlgorithmException
  {
    KeyGenerator localKeyGenerator = KeyGenerator.getInstance("AES");
    try
    {
      SecureRandom localSecureRandom1;
      SecureRandom localSecureRandom2 = SecureRandom.getInstance("SHA1PRNG", "Crypto");
 *    localSecureRandom1 = localSecureRandom2;
 *    localSecureRandom1.setSeed(paramArrayOfByte);
 *    localKeyGenerator.init(128, localSecureRandom1);
      return localKeyGenerator.generateKey().getEncoded();
    }
   catch (NoSuchProviderException localNoSuchProviderException)
    {
      while (true)

 *    SecureRandom localSecureRandom1 = SecureRandom.getInstance("SHA1PRNG");
  }
 }

all fixed, copy and paste error on my part, the infinite loop was for testing.

Answer 1

Assuming you introduced the asterisks ( * ) to highlight the problematic lines:

• localSecureRandom1 is not declared on the first line marked, and that should also be the message the compiler gives you.
• localSecureRandom1 is then declared in the catch -clause, which doesn't make sense
• You also have an infinite loop in your catch -clause
