<\/a> Okay, this is the only way I'm going to prep.<\/p>\n

Tomorrow, I am covering an AP Free Response question at our Super Saturday Tutorial Session.<\/p>\n

It's called String Coder. \"2010-03-05_2302\"<\/a> 
I've pulled the things I think they need from the Quick Reference, String class, List and some code from the Grid World does a for each.<\/p>\n

They get a String Coder class they can use.<\/p>\n

They have to do the following:<\/p>\n

<\/p>\n

\"2010-03-05_2313\"<\/a> <\/p>\n

<\/font><\/font> <\/p>\n

 <\/p>\n

<\/font><\/font><\/p>\n

I always have them write the return stuff first, as that will give some points.<\/p>\n

    String result = "";<\/p>\n

…<\/p>\n

    return result;<\/p>\n

Then I am going to have them figure out how to meet the post condition.<\/p>\n

\tfor (StringPart part : parts)<\/p>\n

   {<\/p>\n

\t    int start = part.getStart();<\/p>\n

\t    int length = part.getLength();<\/p>\n

       result += masterString.substring(start, start+length);<\/p>\n

   }<\/p>\n

Next they have to do:<\/p>\n

\"2010-03-05_2311\"<\/a>
Again, first we have to return an ArrayList of String Part:<\/p>\n

ArrayList<StringPart> result = new ArrayList<StringPart>();<\/p>\n

and <\/p>\n

return result.<\/p>\n

In the middle (instead of and).<\/p>\n

They have to go through the word, searching the parts of the master string <\/p>\n

while (word.length() > 0)<\/p>\n

{<\/p>\n

    StringPart part = findPart(word);   (they will find it according to the pre-condition)<\/p>\n

    result.add(part);<\/p>\n

    word = word.substring(part.getLength());<\/p>\n

}<\/p>\n

<\/p>\n

I'm going to have them give me the answers, I'm going to type the code in and see if it works.  If it doesn't, I'm going to have them debug it.<\/p>\n

I do have code to try.<\/p>\n

If we run out of time, I'll teach them how to program the XBox.  The other AP teachers will probably kill me.<\/p>\n
