I heartily encourage you to learn Java *before* attempting to get into
Android development, simply because most of the Java educational
materials out there are designed for non-Android environments.

There is no point in your instanceof test, as Java is strongly typed,
so it will always be a String. Also, I didn't tell you to *write* an
equals() method, but to *use* the equals() method, as you did inside
your own equals() method.
