// Question #1 on the 2011 AP Exam

// Arrays
// ======
// No Methods
// Use [index]

// new?
// String [] cats = new String[20];
// cats[0] = "Tom";
// cats.length

// int [] numbers = new int[10];
// numbers[0] = 98;
// numbers.length

// Horse [] horses = new Horse[10];
// Access
// horses[0] = new Horse("Silver", 15);



// Things you should do:
// READ the question 2 or 3 times
// Make notes, circle and/or box things
// Circle your instance variables
// Box off the method to write and note the pre and post conditions
// Draw pictures or draw on their pictures
// Think first and understand, then write your code.
// MAKE SURE THAT YOU WRITE YOUR CODE IN THE CORRECT PLACE
