Hashmap Within Hashmap Example Java
This example shows how the values are stored in hashset and hashmap. Here, we have two examples: Java hashmap class implements the map interface which allows us to store key and value pair, where keys should be unique.
If mapping function of this method returns null, then no mapping is recorded for that key. Here, we have two examples: Map<integer, object> targetfields = new linkedhashmap<integer, object> ();
Hashmap class in java extends abstractmap class and implements map, cloneable and serializable interfaces.
1 hashmap<string,string> hmap = new hashmap<string, string>(); If you try to insert the duplicate key, it will replace the element of the corresponding key. One has an inner map of strings, and the other is a map with integer and object values. One object is used as a key (index) to another object (value).
