JPA is the Java Persistence API , which is Java 's standard API for object-relational mapping . JPA is only an specification - you need an implementation of it to be able to use it. Hibernate is one of the most well-known and most used implementations of JPA, but there are others, such as EclipseLink JPA . The Spring Framework is a large framework to help you write enterprise-grade software easier. It contains support for many Java technologies, including JPA. The Spring Framework consists of a collection of projects , and one of these projects is Spring Data . The goal of Spring Data is to make it easier to work with different kinds of databases, from traditional relational databases to NoSQL databases. Spring Data supports JPA via the Spring Data JPA subproject. To write a program that uses JPA, you need at least a JPA implementation, such as Hibernate.

Java Array Interview Questions for Entry-Level Developers Part 01

-
1. What is a Java array? (Definition, purpose, characteristics: fixed size, contiguous memory) Definition A Java array is a data structure that allows storing multiple values of the same data type in a contiguous block of memory. It is a fixed-size collection of elements, each identified by an index. Purpose Arrays are used to efficiently store and manage a collection of data. They provide: Fast access to elements using an index. Memory efficiency since elements are stored contiguously. Characteristics Fixed Size When an array is declared, its size must be specified. The size cannot be changed dynamically (for dynamic collections, use ArrayList or other collections). Contiguous Memory Allocation Arrays are stored in a continuous block of memory, making access faster compared to linked lists. Indexed Access Elements are accessed using zero-based indexing, e.g., array[0] refers to the first element. Homogeneous Elements All elements in an array must be of the same data type. Efficien...
