Why did I have to comment out the last part and use the p array loop. The getPerson() does work, just not in this case, any idea?

why did you not use [code] tags?

I don't see the declaration of personlist. Or the implementation of getPerson, for that matter. Or anything of even remote interest.

Nothing ruins my day more than to see Java code being posted on /prog/. Not to mention that OP didn't even freaking use [code][/code] tags.

Have you read your SICP?

You might want to wrap that commented-out block in a try { ... } catch(NullPointerException e) { } statement.  word1 may not always be "add," in which case you're searching personlist for a word2 that doesn't exist, but proceeding forward with it as if it did exist.  I don't know what the base case of getPerson(String) returns but I'm assuming null if it finds nothing.

If you're going to run with that for loop anyway, unless you allow redundant entries in personlist, break after you find the right person and have outputted their information.

If you're not going to include pertinent source code, methods, etc., do properly explain what it does and what it returns.
