#Day-31   Institute for Advanced Computing and Software Development (IACSD), Pune Today, Mrs. Madhura Anturkar taught us some key concepts in Servlets: 1) Servlet API  - public void init(ServletConfig config) throws ServletException: Initializes the servlet with the given configuration.  - public void service(ServletRequest request, ServletResponse response) throws ServletException: Processes requests and generates responses for each call to the servlet.  - public void destroy(): Cleans up resources when the servlet is terminated. 2) Servlet Deployment Methods  - Using Annotations: Configures servlets directly in the code with annotations like @WebServlet.  - Using XML Configuration: Defines servlets in the web.xml file for centralized configuration. 3) Centralized Exception Handling in Servlets:  - We learned how to manage exceptions in a centralized manner to ensure better error handling and smoother user experiences. 4) Page Navigation Techniques:  - Covered strategies for handling client-side and server-side navigation, including forward, redirect, and link-based navigation. 5) State Management:  - Discussed the importance of state management in web applications and explored techniques like sessions and cookies to maintain data consistency across multiple requests. We also practiced a mini-project that incorporated these concepts, applying the servlet lifecycle methods, deployment techniques, centralized exception handling, and state management. This practical experience helped solidify our understanding and prepare us for real-world web applications. #LetsConnect #100DaysOfCoding #Java #LearnInPublic #OOP #Tech #LetsGrowTogether #BuildInPublic #humanresources #hr, #jobinterviews #hiringandpromotion #jobalert #nowhiring, #job 

#Day-49 Institute for Advanced Computing and Software Development (IACSD), Pune Today, Mrs. Madhura Anturkar covered some essential topics in web development and Spring: 1) Model Attributes A ModelAttribute is an object used to share data between the controller (handler) and the view layer in an MVC application. We discussed two ways to send model attributes to the Dispatcher Servlet:  - ModelAndView  - Model 2) Redirect vs. Forward We learned how to replace a "forward" with a "redirect" in controllers. Redirecting is especially useful for avoiding duplicate form submissions and implementing PRG (Post-Redirect-Get) patterns. 3) Session Management We covered using HttpSession to track a client’s data across multiple requests, a key approach for implementing user sessions and handling persistent data on the server side. 4) MVC Architecture Layers We examined the typical layers in the MVC (Model-View-Controller) pattern, understanding the distinct roles each layer plays in separating data, user interface, and control logic. 5) Introduction to the Spring Boot Framework Ma'am introduced us to Spring Boot, a framework that simplifies the setup and development of Spring applications. We discussed its purpose, benefits, and how it streamlines the process of creating stand-alone, production-grade Spring-based applications with minimal configuration. Overall, today’s session was highly informative, setting a solid foundation for more advanced topics in web applications and Spring. #LetsConnect #100DaysOfCoding #Java #LearnInPublic #OOP #Tech #LetsGrowTogether #BuildInPublic #humanresources #hr, #jobinterviews #hiringandpromotion #jobalert #nowhiring, #job #NewJob, #NewRole, #CareerChange, #Networking, #PersonalBranding, #Employment, and #ProfessionalDevelopment #HiringNow, #JobOpening, #NowHiring

#Day-32 Institute for Advanced Computing and Software Development (IACSD), Pune Today, Mrs. Madhura Anturkar taught us some advanced Java topics: 1) Cookie-Based Session Tracking We learned how cookies help in session tracking by storing user information on the client side. Key methods covered:  - setMaxAge(int expiry): Sets the maximum age in seconds for the cookie.  - getMaxAge(): Retrieves the maximum age of the cookie.  - getName(): Gets the name of the cookie.  - getValue(): Gets the value associated with the cookie. 2) HttpSession Interface We explored the HttpSession interface, which helps manage user-specific data across multiple requests in a web application. Important methods include:  - getId(): Retrieves the unique session ID assigned by the server.  - setAttribute(String name, Object value): Adds or updates an attribute bound to this session.  - getAttribute(String name): Retrieves an attribute value based on the provided name.  - removeAttribute(String name): Removes an attribute associated with the session.  - invalidate(): Ends the session and removes all bound attributes. 3) HttpSession Life Cycle We studied the stages of the session life cycle, from creation to termination. Key stages include:  - Session Creation: Triggered upon a new user request, often through request.getSession(true).  - Session Management: Maintaining sessions using cookies or URL rewriting.  - Session Invalidation: Sessions can be invalidated through invalidate() or upon reaching the maximum inactive interval. To put these concepts into practice, we created a Voting Management Project. This project involved: Using cookies to track each user’s vote to prevent multiple voting. Managing user sessions through HttpSession to store voting information securely and reliably across multiple interactions. Implementing session expiration to ensure a secure voting process. #LetsConnect #100DaysOfCoding #Java #LearnInPublic #OOP #Tech #LetsGrowTogether #BuildInPublic #humanresources #hr, #jobinterviews #hiringandpromotion #jobalert #nowhiring, #job 

#Day-24  Institute for Advanced Computing and Software Development (IACSD), Pune As we near the end of our Core Java module, today we had another insightful session with Mrs. Madhura Anturkar Ma'am. She covered several important topics related to Multithreading and more. Here are the key concepts we learned: 1) #Multithreading Methods:  - public void start()  - public static void yield()  - public void setName(String name)  - public String getName()  - Thread priority and its scale  - public static Thread currentThread()  - public String toString()  - public static void sleep(long milliseconds)  - public void interrupt()  - public void join()  - public void join(long milliseconds) 2) Blocking vs. Non-blocking Triggers: 3) Blocking triggers halt thread execution, while non-blocking triggers allow other threads to continue. 4) Race Conditions: Race conditions occur when multiple threads access shared resources simultaneously, causing unpredictable outcomes. 5) Critical Sections: Critical sections are parts of code where shared resources are accessed, requiring careful management to avoid race conditions. 6) #Synchronization: Synchronization ensures only one thread accesses a critical section at a time, preventing conflicts and maintaining data integrity. The session included practical examples on multithreading, thread behavior, and synchronization techniques to avoid race conditions. #LetsConnect #100DaysOfCoding #Java #LearnInPublic #OOP #Tech #LetsGrowTogether #BuildInPublic #humanresources #hr, #jobinterviews #hiringandpromotion #jobalert #nowhiring, #job
