Java Multithreading Basics and Practice

Day 20– Multithreading Basics Today I explored Multithreading in Java, a concept that allows multiple tasks to run simultaneously. Instead of executing tasks one by one, threads help improve performance by running processes in parallel. Things I learned today: 🔹 What is a thread 🔹 Difference between process and thread 🔹 Creating a thread using Thread class 🔹 Importance of start() and run() 💡 Key takeaway: Multithreading helps in building efficient and high-performance applications by executing multiple tasks at the same time.

Today I learned about Abstraction in Java. Abstraction is a core concept of Object-Oriented Programming that focuses on hiding implementation details and showing only essential functionality. To understand it better, I implemented a simple payment system using an abstract class. Through this example, I understood: - How abstract classes work - How implementation is hidden from the user - How different behaviors can be achieved using the same structure I’m continuing to strengthen my understanding of Java and OOP concepts. #Java #Abstraction #OOP #LearningJourney

Today, I explored one of the core concepts of Object-Oriented Programming — Polymorphism in Java. - Understood how a single interface can represent multiple behaviors. - Practiced method overriding and runtime polymorphism. - Implemented real examples using inheritance and dynamic method dispatch. This concept really changed how I think about writing flexible and scalable code.

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.

Day 43-What I Learned In a Day(JAVA) Today I worked on String concepts in Java and practiced some interesting problems. What I learned: Creating and using strings in Java Converting a number into an array using strings Handling characters using charAt() Problems I practiced: ✅ Created and manipulated strings ✅ Converted number -array using string ✅ Moved zeros to the end of an array These problems helped me understand how strings and arrays work together and improved my problem-solving skills.

Day 9: Interfaces After abstraction, the next important idea is interfaces. An interface defines a contract. It tells a class what behavior it must provide, without giving the full implementation itself. In Java, a class uses `implements` to follow that contract. This makes code more flexible, because different classes can follow the same interface in their own way. #Java #OOP #Programming #SoftwareEngineering #ComputerScience #koofkee

How does Java manage memory without pointers? String str = new String("Hello"); str = null; When the reference is removed, the object is not deleted immediately. It simply becomes eligible for Garbage Collection. 👉 Eligibility ≠ Immediate deletion Java’s Garbage Collector automatically cleans such objects in the background, making memory management easier and safer. 💡 Understanding this concept helps in writing better and more efficient code. #Java #Programming #JavaDeveloper #Coding #ComputerScience #MemoryManagement

Day 21– Thread Methods in Java Today I explored how to control threads in Java using different methods. Things I learned: 🔹 start() – begins thread execution 🔹 run() – contains logic (called internally) 🔹 sleep() – pauses thread for a specific time 🔹 join() – ensures one thread finishes before another starts 💡 Key takeaway: Thread methods help manage execution flow and improve control over multithreading behavior.

Here is a Java code snippet on MethodOverloading. Excited to share how i explored using the same method name with different datatypes in java. #java #coding #programming @Raviteja T @10000coders

Nested types are a powerful way to organize and encapsulate logic in Java — but understanding the difference between static and non‑static nested types is key to using them effectively. This post breaks down how each kind works, how they access outer class members, how instances are created, and what the compiler does behind the scenes. Whether you’re structuring helper classes or managing deeper hierarchies, mastering nested types will help you write cleaner, more maintainable Java code. #Java #Programming #SoftwareDevelopment #RheinwerkComputingBlog Read the full post: https://hubs.la/Q048Shz50
