 Astronaut Sunita Williams and her colleague, Barry "Butch" Wilmore, recently returned to Earth after an unexpected nine-month mission aboard the International Space Station (ISS). Originally scheduled for a brief eight-day stay, their mission was extended due to technical issues with the Boeing Starliner spacecraft, leading to a prolonged 286-day duration in space.  Mission Extension and Challenges The mission's extension was primarily due to propulsion problems with the Starliner craft, necessitating their continued presence on the ISS. This unforeseen prolongation presented both physical and psychological challenges for the astronauts. Prolonged exposure to microgravity can lead to muscle atrophy, bone density loss, and other health concerns. To mitigate these effects, astronauts adhere to rigorous exercise regimens while aboard the station.  Health Observations Upon Return Upon their return, noticeable physical changes were observed, particularly with Sunita Williams,...

 Java Development Kit (JDK) 25, scheduled for release in September 2025, is set to introduce several significant enhancements. Here's an overview of the notable features: 1. Stable Values API (Preview): This feature introduces stable values—objects holding immutable data treated as constants by the Java Virtual Machine (JVM). By allowing greater flexibility in initialization timing compared to final fields, stable values aim to improve application startup times. They enable performance optimizations akin to constant-folding, previously exclusive to JDK code, and ensure thread-safe, single-time initialization. This decouples the creation of stable values from their initialization without significant performance penalties.  2. Removal of 32-bit x86 Port: JDK 25 plans to eliminate both the source code and build support for the 32-bit x86 port, which was deprecated in JDK 24. Maintaining this port has become less beneficial, especially with the challenges in keeping it updated wit...

How to Parse JSON with Date Field in Java - Jackson `@JsonDeserialize` Annotation Example Parsing JSON in Java is a common task, but dealing with date fields requires a little extra attention. JSON treats everything as a string, but Java has strong typing, meaning dates need to be handled differently. In this post, we will see how to parse a JSON with a date field using Jackson, focusing on the `@JsonDeserialize` annotation. Example Scenario Let’s assume we have a simple JSON that includes a date field: ``` {   "name": "John Doe",   "birthDate": "2024-09-05" } ``` In Java, we might want to map this to a class with a `LocalDate` for `birthDate`. This is where Jackson's `@JsonDeserialize` annotation comes into play. Step-by-Step Example Step 1: Add Jackson Dependency First, make sure you have the Jackson dependency in your `pom.xml` if you’re using Maven: ``` <dependency>     <groupId>com.fasterxml.jackson.core</groupId>     ...

 In modern Java applications—whether core Java applications or enterprise-level web applications—working with passwords is inevitable. Passwords are sensitive pieces of information, just like Social Security Numbers (SSNs), and if you’re handling real human data in systems such as online banking or healthcare portals, it’s critical to implement best practices for dealing with passwords securely. Below, I’ll share five essential best practices that I’ve learned and recommend for managing passwords, particularly when you are handling authentication and authorization. While these tips are a good starting point, be sure to tailor them to your application’s requirements and security policies. 1) Use SSL/TLS to Transfer Username and Password When users send passwords over the network, it is crucial to use SSL/TLS to encrypt the communication. This ensures that sensitive information is protected from eavesdroppers. Tools like LDAP and Active Directory are commonly used for storing usern...

How to create Immutable Class and Object in Java - Tutorial Example Writing or creating immutable classes in Java is becoming popular day by day, because of the concurrency and multithreading advantages provided by immutable objects. Immutable objects offer several benefits over a conventional mutable object, especially while creating concurrent Java applications. An immutable object not only guarantees the safe publication of an object’s state but also can be shared among other threads without any external synchronization. In fact, JDK itself contains several immutable classes like String , Integer , and other wrapper classes. For those who don’t know, immutable objects are those whose state cannot be changed once created. A good example is java.lang.String — once created, a String object cannot be modified. Any operation that seems to modify a String object (like trim() , toUpperCase() , etc.) actually results in a new object. What is an Immutable Class in Java? An immutabl...

Clean Architecture with Spring Boot: In the world of software development, architecture plays a crucial role in determining the maintainability, scalability, and testability of an application. One architecture style that has gained popularity is Clean Architecture . But what exactly is Clean Architecture, and is it a good idea to use it with Spring Boot? Let’s dive in! What is Clean Architecture? Clean Architecture is a software design philosophy introduced by Robert C. Martin, also known as "Uncle Bob." The main idea behind Clean Architecture is to separate the concerns of your application into distinct layers, making your codebase more modular, easier to maintain, and less dependent on external frameworks. The Layers of Clean Architecture Clean Architecture is typically divided into the following layers: 1. Entities : The core business logic of your application. This layer is independent of any external system or framework. It contains the business rules that are critical t...
