In programming and software, Java is mostly preferred as the first choice for many programmers. The reason why most programmers use Java. It gives the best result in no time. It is fast and easy to use. You can find varieties of libraries in Java that helps in building a language.
Many students are pursuing this field of computer programming language because they are in great demand. Java is a platform where you can create a new programming language with some unique tools to use.
The Hibernate is an open-source framework in Java. It works on the principle of ORM (Object Relational Mapper). The reason why many programmers extensively use hibernate is that it’s lightweight. Due to its lightweight, it can perform the actions fast.
Hibernate framework consists of independent database queries like HQL (Hibernate Query Language). It can draw data from a variety of tables that simplifies the complex issues in the Hibernate framework.
The main function of Hibernate is to process and store the essential data for extensive use. It can easily work with many technologies like servlet, JDBC, and much more.
Looking at such different aspects and availability of such tools. Many students are planning to appear for the interview. It has got a variety of benefits to give which encourages the students. To be a skilled programmer.
Let’s have a look at the most tricky Hibernate Interview Questions below.
Top Tricky Hibernate Interview Questions
What is Hibernate?
It is the most obvious question that every interviewer will ask. However, it is not a tricky question but an expected one. Hibernate comes under the category of the most popular framework in Java. The database interacts with the development made by the programmer of the Java application. It works on the principle of ORM (Object-relational Mapper).
It has an abstraction layer that internally switches the implementation of an application. Hibernate is a lightweight framework with some powerful tools. It progresses persistent logic that helps in the processing and storage of data for further use.
What are the advantages of using Hibernate over JDBC?
Hibernate has tons of features and advantages, like it supports Connotations, assortments, and inheritance in the Java framework. Whereas on the other, all the features mentioned above don’t work in JDBC. JDBC is much oriented towards SQL (Structured Query Language). While Hibernate is much oriented towards Java and HQL (Hibernate Query Language).
In Hibernate, you don’t have to worry about writing codes as it has got in-built transaction management that eliminates the practice of try-catch blocks. While in the JDBC, you have to engrave tons of try-catch blocks code.
The code airs cleaner and understandable in the Hibernate, eliminating tons of codes like boilerplate, which comes straight with the JDBC API. With the help of rollback and commit, JDBC writes the code for transaction management. At the same time, Hibernate uses simplicity for transaction management.
What is a One-to-one association in Hibernate?
It is much more parallel to the many-to-one association. It is different in one condition to the many-to-one association because it has to be set unique in the one-to-one association. The one-to-one association can also be defined with the help of the elements in the many-to-one association.
For a defined variable, a column name in the parent table is a must in the field of column attribute. And in the parent class, a name attribute is a must. The only single object gets associated with another because it has a unique feature.
Explain the key components of Hibernate?
Query – the object is created when the system uses HQL and SQL string as it uses the string to collect the important data from the database.
Criteria – this key component helps to collect the objects and to implement and build object-oriented queries.
Session Factory – this key component helps organize hibernate for the instantiates the session object, and with the provided configuration file, it forms the application.
Configuration – this key component in the Hibernate embodies the properties of files which is mandatory for the process.
Transaction – this key component deals with the database of the Hibernate that signifies the unit of work.
Session – this key component deals with the database of the Hibernate to attain the physical network.
What are some of the databases that Hibernates supports?
Hibernate has the potential to provisions all the chief relational databases. There is ample list that supports Hibernate are as follows. MySQL, Sybase SQL Server, Oracle, HSQL Database Engine, Microsoft SQL Server Database, PostgreSQL, FrontBase, and Informix Dynamic Server.
What personality will you bring to the team?
Again, a very basic yet easy answer which will define your personality. So, while answering this, you must show how you work, your presence of mind, your anger management, and a lot of other stuff to look after.

It will also make all the tricky points very clear as all the answers are mentioned in the article and are the easiest to deal with. Many students are drifting to this field as it is more diverse than any other sector. IT sector has boomed in recent time that has a great opportunity for the upcoming generation to build some outstanding programs.
