#Day81 of #100DaysOfCode Focused on understanding functions (methods) in Java and how to write reusable code. Covered: - Creating functions with and without return types - Passing parameters and using arguments - Implementing logic using functions Practiced problems like sum calculation, even/odd check, and factorial using functions. #Java #Programming #Functions #100DaysOfCode

💫@𝐏𝐫𝐢𝐦𝐚𝐫𝐲 𝐯𝐬 @𝐐𝐮𝐚𝐥𝐢𝐟𝐢𝐞𝐫 𝐢𝐧 𝐒𝐩𝐫𝐢𝐧𝐠 𝐁𝐨𝐨𝐭: When working with dependency injection in Spring Boot, handling multiple beans of the same type can get tricky. That’s where @Primary and @Qualifier come into play 👇 👉 @Primary Used to define a default bean. If multiple beans exist, Spring automatically picks the one marked as @Primary. 👉 @Qualifier Used to explicitly specify which bean you want. Gives you precise control over dependency injection. 💡 Key Insight: Use @Primary for default behavior and @Qualifier when you need specific control. Together, they make your code more flexible and maintainable. #SpringBoot #JavaDeveloper #BackendDevelopment #DependencyInjection #SpringFramework #Java #Coding #SoftwareDevelopment #TechLearning #Developers #Programming #100DaysOfCode #JavaBackend #SpringAnnotations 𝐓𝐡𝐚𝐧𝐤𝐬 𝐭𝐨 𝐦𝐲 𝐌𝐞𝐧𝐭𝐨𝐫: Anand Kumar Buddarapu Saketh Kallepu Uppugundla Sairam

Looks the same… But behaves completely different 🤯 That’s Java for you 🧠 Two values can look identical, but if their types are different — the result changes ⚠️ This is where many developers get confused… Not because the code is complex, but because the concept is subtle. In Java, understanding types matters more than just values.

Day 45-What I Learned In a Day (JAVA) Today I explored some important concepts related to static in Java: 🔹 Static Method Learned how static methods belong to the class and can be called without creating an object. 🔹 Static Initializer (Static Block) Understood how a static block is executed only once when the class is loaded. 🔹 Single-Line Static Initializer Explored how we can initialize static variables in a single line. 🔹 Multi-Line Static Initializer Learned how to use static blocks for complex initialization logic.

Multithreading made more sense to me once I simplified it 👇 Multithreading = running multiple threads at the same time 😉 A thread is basically a lightweight unit of execution (smaller than a process, faster, and shares memory) Why use multithreading? ✔ Perform multiple tasks together ✔ Better performance ✔ Doesn’t block the entire program ✔ Efficient use of memory In Java, there are 2 main ways to create threads: 1️⃣ Extending the Thread class 2️⃣ Implementing the Runnable interface 👉 Runnable is generally preferred because it’s more flexible and reusable Thread lifecycle (simplified): New → Runnable → Running → Blocked → Terminated Some commonly used methods: • start() → begins execution • run() → contains the task • sleep() → pauses execution • join() → waits for another thread One thing I realized: 👉 Multithreading is powerful, but it also adds complexity So understanding when to use it matters more than just knowing how. Still learning this, but things are starting to connect now 💡 If you’ve worked with multithreading, what confused you the most in the beginning? 👇 #Java #Multithreading #BackendDevelopment #Developers #LearningInPublic #Programming
