Document doc = Jsoup.connect("http://directory.binghamton.edu/directory/directory.deptlist").get();
System.out.println(doc);
Elements departments = doc.select("deptlist");

Here we go!

Document doc = Jsoup.connect("http://directory.binghamton.edu/directory/directory.deptlist").get();

Elements departments = doc.select("table#deptlist a"); // Select all 'a' in a 'table'-tag with id 'deptlist'
String name;


for( Element element : departments ) // Iterate over all Elements available
{
    name = element.text(); // Save the plaintext (no html) of the element
    System.out.println(name); // Simple output (as an example)
}

In your code you select a tag 'deptlist' not the table.
If you want to select all elements with id=deptlist (in my example you select only tables with that id's) you can use this selector: doc.select("#deptlist") .
