Date.java

+public class Date { 
+  public int day; 
+  public int month; 
+  public int year;
+}

Instructions.md

+1. Run this code to ensure it does what you expect
+2. Change `day` from **public** to **private**
+   Does the code still run? Why not?
+3. Create a new method `setDay(int day)`. This method should check to ensure 0 < day < 32
+   Modify `main()` to use this method rather than setting day directly. Does this fix the code?
+4. Create a new method `getDay()` that returns the value of day. Update main to use `getDay()` in the 
+   output line.
