New Hashmap Java
Map<String, String> myMap = new HashMap<String, String>() {{
put("a", "b");
put("c", "d");
}};
Fair Fly
Map<String, String> myMap = new HashMap<String, String>() {{
put("a", "b");
put("c", "d");
}};In computing, a hash table (hash map) is a data structure that implements an
associative array abstract data type, a structure that can map keys to values.
A hash table uses a hash function to compute an index, also called a hash code,
into an array of buckets or slots, from which the desired value can be found.
HashMap hm=new HashMap(int initialCapacity, float loadFactor); import java.util.HashMap; // import the HashMap class
HashMap<String, String> capitalCities = new HashMap<String, String>();
