Compare ArrayList and LinkedList data structures in Java. Explore their differences in implementation, time complexity, memory usage, and guidance on when to use each based on use cases.

Discover 7 Java libraries for better unit and integration testing: AssertJ, Awaitility, Mockito, Wiser, Memoryfilesystem, WireMock, and Testcontainers. Simplify development, reduce testing time, and ensure code quality.

Hibernate requires the configuration of a SQL dialect in order to generate appropriate SQL statements for the specified database type. The org.hibernate.dialect package contains many Dialect classes for various RDBMS.

This article discusses the differences between TreeMap, HashMap, and LinkedHashMap in Java. It explains the characteristics and use cases of each of these classes to help you choose the right implementation of the Map interface for your project.

This article explores the Dependency Inversion Principle (DIP) in SOLID design principles, highlighting the benefits of creating flexible and easy-to-maintain code. It provides a Kotlin example for implementing DIP to achieve an adaptable codebase.

Learn how to use JUnit 5's feature for ordering test classes to run Spring Boot automated tests from unit to integration tests, with the fastest tests running first. Configure JUnit with a ClassOrderer for a predetermined order.

This article explains the Interface Segregation Principle (ISP), a SOLID design principle. ISP says that a class should only implement the methods it needs. The article gives an example of a bad practice that violates ISP and a better practice that follows it by creating small, specific interfaces for each class.

Implementing a Cache with Spring is a fairly easy task, due to the ease of implementation. For this Spring provides us with a series of annotations that we will see in the rest of the tutorial.

The Liskov substitution principle ensures that subclass objects can be used interchangeably with those of the superclass, preventing unexpected program errors. Adhering to this rule simplifies code management and increases predictability.

This article explains the Open-Closed Principle (OCP) of SOLID design, which advises creating flexible and maintainable code by keeping classes open to extension but closed to modification. It uses an example to show how to adhere to the OCP by defining an interface and creating separate classes for each shape.

The Single Responsibility Principle (SRP) is a design principle promoting maintainable code. It states that each class should have only one job. This post explains its importance with code examples, resulting in more understandable and maintainable code.
