Java Interview Shorts 3 - What is an Entry object ? Java collections framework interview questions

In this video we will learn about Entry object in java. Entry is a nested interface present inside a java Map interface. Inside a map , we store key and value pair but we don’t store them directly. We store entry object inside a map (like Hashmap or treemap) which is a wrapper for the key and value objects.

The entry object can be accessed using Map.Entry as it is a nested interface.To access all the entries of a map objects use the entrySet() method and then use the getKey and getValue methods to access a specific entry’s key and value.
