CSC152 2006S, Class 26: Arrays and Vectors

Admin:
* Homework:
  * Do the vectors lab on your own.  (Nothing to submit.)
  * Read all about (a) linear structures; (b) stacks.
* Request: Play a silly game.

Overview:
* Basics of vectors and arrays.
* Lab.

* Need ways to organize and store data
  * A File
  * The array (like Vectors in Scheme)
* Array:
  Fixed-size collection of data
  Provides three main operations // Not with this syntax
  * Get(int i)
  * Put(int i, T value)
  * size()
* In Java, fairly simple, but ugly
* Because ugly and non-expandable, Java also provides Vectors

public static void printGrades(PrintWriter pen, String[] names, int[] grades)
{
} // printGrades(PrintWriter, String[], int[])
