  • Q3. Singleton design patterns
  • Q4. What is dependency injection
  • Ans. 

    Dependency injection is a design pattern where components are given their dependencies rather than creating them internally.

    • Dependency injection helps in achieving loose coupling between classes.

    • It allows for easier testing by providing a way to mock dependencies.

    • There are three types of dependency injection - constructor injection, setter injection, and interface injection.

  • Q5. N+1 problem of hibernate
  • Ans. 

    The n+1 problem in Hibernate occurs when a query results in multiple individual queries being executed for each row fetched.

    • Occurs when a query fetches a collection and then for each element in the collection, another query is executed to fetch related data

    • Can be resolved by using fetch joins or batch fetching to reduce the number of queries

    • Improves performance by reducing the number of database round trips
