List-Set-Map-Interfaces-Java

In Java, the Set and Map interfaces are integral components of the Java Collections Framework, designed to facilitate the storage and manipulation of collections of objects. The Set interface represents a collection of unique elements, ensuring that no duplicates are allowed, while the Map interface provides a structure for storing key-value pairs, allowing for efficient data retrieval based on keys. Common implementations of the Set interface include HashSet and TreeSet, whereas HashMap and TreeMap are popular implementations of the Map interface. Understanding these interfaces is essential for effective data management in Java applications.
