Answer 1

No need to reinvent the wheel, use a NavigableMap. Example Code:

final NavigableMap map = new TreeMap();
map.put(0, "Cry Baby");
map.put(6, "School Time");
map.put(16, "Got a car yet?");
map.put(21, "Tequila anyone?");
map.put(45, "Time to buy a corvette");

System.out.println(map.floorEntry(3).getValue());
System.out.println(map.floorEntry(10).getValue());
System.out.println(map.floorEntry(18).getValue());

Output:

Cry Baby
School Time
Got a car yet?
