- Q1. Explain association, aggregation and composition.
- Ans.
Association, aggregation, and composition are types of relationships between classes in object-oriented programming.
Association is a relationship where two classes are related in some way, but not dependent on each other. Example: a student and a teacher.
Aggregation is a type of association where one class contains a reference to another class, but the referenced class can exist independently. Example: a car has an eng...
- Q2. Diff bw put and post mapping
- Ans.
PUT is used to update or replace an existing resource, while POST is used to create a new resource.
PUT is idempotent, meaning multiple identical requests will have the same effect as a single request.
POST is not idempotent, meaning multiple identical requests may have different effects.
PUT is typically used for updating an existing resource, like updating a user's information.
POST is typically used for creating a new r
- Q3. Internal working of hashmap
- Ans.
HashMap is a data structure that stores key-value pairs and uses hashing to efficiently retrieve values.
HashMap internally uses an array of linked lists to store key-value pairs.
When a key-value pair is added, the key is hashed to determine the index in the array where it will be stored.
If multiple keys hash to the same index, a linked list is used to handle collisions.
To retrieve a value, the key is hashed again to fi...
- Q4. Explain functional interface
- Ans.
Functional interface is an interface with only one abstract method, used for lambda expressions.
Functional interfaces can have multiple default or static methods, but only one abstract method.
