交互设计算法基础（4） - Hash Table

 import java.util.Map;
 
 // Note the HashMap's "key" is a String and "value" is an Integer
 HashMap<String,Integer> hm = new HashMap<String,Integer>();
 
 // Putting key-value pairs in the HashMap
 hm.put("Ava", 1);
 hm.put("Cait", 35);
 hm.put("Casey", 36);
 
 // Using an enhanced loop to interate over each entry
 for (Map.Entry me : hm.entrySet()) {
   print(me.getKey() + " is ");
   println(me.getValue());
 }
 
 // We can also access values by their key
 int val = hm.get("Casey");
 println("Casey is " + val);

Processing内建HASH Table（哈希表），倒是挺方便的，就不用自己动手写啦!!☆⌒(*＾-゜)v
