Arrays

• Using the value stored:
  System.out.println("The value of this data item is " + data[4]);
• Get array length as data.length. (Not a method!)
• Index values range from 0 to length - 1
• Accessing a nonexistent element results in a bounds error
  double[] data = new double[10];
  data[10] = 29.95; // ERROR
• Limitation: Arrays have fixed length
