unnecessary. You has check this condition above, too.

You can in this cases write return false;

Same thing as above. return true;

Instead of == false use the not-operator !

Instead of this monster. You can use a = hash1.equals(hash2); For checking the equality of the HashMaps.

Remove unnecessary empty lines.
