Get Items

You can get the value associated with a key by using .get. If there is no value associated with that key it will return null.

import java.util.HashMap; class Main { void main() { var wins = new HashMap<String, Integer>(); wins.put("Lightning McQueen", 2); wins.put("Tow Mater", 0); System.out.println(wins.get("Tow Mater")); System.out.println(wins.get("Doc Hudson")); } }
