Kotlin vs Java for Android Development

🚀 Java Concept Series Java is a high-level, object-oriented language based on “Write Once, Run Anywhere.” It is widely used in real-world applications like: ✔ Banking systems ✔ Android apps ✔ Web applications ✔ Enterprise software 👉 Next: JVM, JDK, JRE (core basics) #Java #Programming #PlacementPreparation #LearnInPublic #CodingJourney 

Want your apps to run faster and smoother? 💻 👉 You need Multithreading It allows your program to handle multiple tasks at the same time — like: ✔ Downloading files ✔ Updating UI ✔ Processing data 👉 All at once ⚡ 💡 In Java, this is done using:...

Can a competing language actually help save Java? This article looks at a provocative idea: Kotlin may be one of the main reasons Java started evolving faster again. It covers practical points developers care about: - why Kotlin gained so much traction on Android and backend - which Java features arrived after Kotlin had already made similar ideas familiar on the JVM - why Kotlin may be pushing the whole JVM ecosystem forward, not just competing with Java A good read for developers interested in Kotlin, Java, and where JVM development is heading next. 👉 https://lnkd.in/dZ5AnKVn #Kotlin #Java #JVM #AndroidDevelopment #BackendDevelopment #SoftwareDevelopment

🔹 What is an Interface in Java? An interface is a blueprint of a class that contains only abstract methods (method without body). It tells "what to do" but not "how to do". - Example: A remote control – it has buttons, but how the TV works internally is hidden. - Key Points: ✔ All methods are abstract by default (before Java 8) ✔ Supports multiple inheritance ✔ Used to achieve 100% abstraction + Why use interface? - Improves flexibility - Supports multiple inheritance - Helps in loose coupling #fortunecloudtechnology #Java #MultipleInheritance #Interface #OOP

Java and Kotlin run on the same JVM, share the same ecosystem, and can even call each other's code. So why does picking one still feel complicated? Because the right choice depends on what you're building, not which language is objectively better. This decision tree makes it straightforward (see photo below) The full guide by roadmap.sh goes deeper, covering key differences in syntax, null safety, concurrency, and long-term maintenance so you can make a decision now that actually holds up later.

Java might be one of the “oldest” mainstream languages in tech, but it’s still evolving strongly in modern systems. With improvements in performance, virtual threads, and better cloud-native support, Java continues to power large-scale distributed applications.

⚠️ Deadlocks in Java — Small mistake, big problem. Deadlock occurs when two threads wait on each other forever. Thread 1 → holds Lock A, waiting for Lock B Thread 2 → holds Lock B, waiting for Lock A And the application just… freezes. 💡 How to avoid it: → Always follow a consistent lock order → Avoid unnecessary nested locks → Use tryLock() with timeout → Prefer high-level concurrency APIs Multithreading is not just about performance — it’s about writing safe and predictable code. #Java #Multithreading #Deadlock #Concurrency #BackendDevelopment

Ever been confused about what "Platform Independent" really means for Java? This infographic provides the clearest answer I've seen. Is Java Platform Independent? YES. But here is the crucial distinction that often gets overlooked: Java is Platform-Independent, while the JVM is Platform-Dependent. This is the core magic behind "Write Once, Run Anywhere." As the diagram perfectly visualizes, it's a two-step process: Step 1: Compilation Your Java Source Code (.java file) is compiled by javac into universal, platform-neutral Java Bytecode (.class file). This Bytecode is the single, universal binary. Step 2: Run Anywhere (The Key) This same single Bytecode file can then travel to any platform. BUT, for it to execute, that specific platform must have its own platform-specific Java Virtual Machine (JVM). The universal Bytecode goes into a JVM for Windows. The universal Bytecode goes into a JVM for macOS. The universal Bytecode goes into a JVM for Linux. The JVM acts as the final translator (an abstraction layer), taking that neutral Bytecode and converting it into the native machine instructions of that specific hardware and operating system. It's a powerful separation of concerns: you write and compile your code once, and the JVM handles the last-mile translation for any device.

🚀 The if-else Statement (Java) The 'if-else' statement provides an alternative code block to execute when the 'if' condition is false. If the boolean expression in the 'if' statement is true, the first code block is executed; otherwise, the code block within the 'else' statement is executed. This allows for handling two distinct scenarios based on a single condition. 'if-else' statements are a cornerstone of decision-making in programming.

Today I focused on understanding why Java is so popular using W3Schools and GeeksforGeeks. Key takeaways: • Java is platform independent (Write Once, Run Anywhere) • It uses JVM to run code on any system • Strongly object-oriented → helps in building scalable applications • Used in real-world systems like web apps, enterprise software, and Android I also revised the basic structure of a Java program and practiced simple code. Understanding why we learn something makes the journey more meaningful 💡 Slowly building consistency 🚀 #Java #CodingJourney #LearningInPublic #GeeksforGeeks #W3Schools
