Q: load() method
load() method is used to retrieve an object from the database by its identifier (primary key). It is used to initialize a proxy object instead of a fully-initialized object, so it can be used to lazily load the object when it is needed.
load() method does not retrieve the object from the database when it is called. Instead, it returns a proxy object that represents the object. The actual object is only retrieved from the database when it is needed, such as when a method of the object is called or a property is accessed. This technique is known as “lazy loading” and it is used to improve the performance of Hibernate by avoiding unnecessary database queries.

What is DOM in Java?
DOM addresses the Document Object model. The point when an article contains some data about XML reports is called DOM Parser. This seems to be a tree structure. DOM API is carried out by a DOM Parser, which is extremely simple and easy to utilize. It addresses an XML Document into a tree design in which every component addresses tree limbs, makes an In Memory tree portrayal of the XML record, and then parses it. More memory is expected for this.

What is Actuator in spring boot
Actuator is mainly used to expose operational information about the running application — health, metrics, info, dump, env, etc. It uses HTTP endpoints or JMX beans to enable us to interact with it. Once this dependency is on the classpath, several endpoints are available for us out of the box.
