Data Structures Book FAQ and Errata

There's been at least one report of problems using the Macintosh version of DrJava in adding to the "Extra Classpath." Here's a movie of doing it: http://www.cc.gatech.edu/~mark.guzdial/AddingExtraClasspath.mov The trick is to double-click on the folders to enter them. If you click the Select button, you select the folder instead of entering it.
Page 234: The caption and figure should say tree.getRoot() not tree.root(). We changed the name of the accessor to be more in Java style, but forgot to update the figure.
Page 252: The last three lines of Java Code 81 currently say:

StudentNode node = (StudentNode) node1.getNext();
node = (StudentNode) node.getNext();
System.out.println(node.getStudent());


But as is evident from the following code which fixes this code, it was supposed to say:

System.out.println(node1.getNext().getNext().getStudent());


This was an example of having faulty code that we'd lead a student through fixing – but instead, including the fixed code!
Page 260: Strike implements BTreeNode from Java Code 82. The code got modified to implement Exercise 10.1, and we accidentally included the modified code.
