SET08112 ArrayList Interface Tutorial

In this tutorial you will use the ArrayList and the HashMap or TreeMap to solve some common problems. You will use methods such as:

  • java.util.Collections.sort
  • add
  • get

Problem 1 - Sort a List

The file from http://www.dcs.napier.ac.uk/~cs66/SET08112/tut2/students.txt contains a list of students:

ADAMS, ROBERT
HASTIE, MARTIN
OTHIENO, JUDITH
ANDERSON, ROSS
...

Create a programme SortStudents.java that reads in this file and outputs the students in Alphabetical order.

  • You can use an ArrayList to hold the students.
  • ArrayList<String> names = new ArrayList<String>();
  • You can use java.util.Collections.sort to sort the ArrayList
