💡 Multithreading in Java 🧵 Thread: A thread is the smallest unit of a process that runs independently and executes a specific task. ⚙️ Multithreading: Multithreading in Java is the process of executing multiple threads concurrently, enabling applications to perform several tasks simultaneously. 🎯 Main Purpose: The main objective of multithreading is to utilize CPU time efficiently and improve the performance and responsiveness of applications. 🛠️ Ways to Create Threads in Java: 1️⃣ By extending the Thread class 2️⃣ By implementing the Runnable interface 🔹 run() Method: The run() method defines the code that a thread will execute. It represents the task that needs to be performed by the thread. 👉 If you call run() directly, it executes like a normal method — not in a new thread. 🔹 start() Method: The start() method is used to start a new thread. It internally calls the run() method but in a separate call stack, enabling concurrent execution. 👉 Always use start() to begin a new thread; calling run() directly won’t create a new thread. #Java #Multithreading #Threads #JavaDeveloper #Learning #TapAcademy #Concurrency #Coding #Programming

🚀 Multithreading in Java using a Single run() Method In Java, Multithreading allows multiple parts of a program to run concurrently, helping us utilize CPU time efficiently and improve performance. A thread is a lightweight subprocess — the smallest unit of processing. We can create multithreading in Java using: Extending the Thread class Implementing the Runnable interface However, we can also handle multiple tasks using a single run() method by managing the logic of different threads inside it. 🔹 Example Concept: A single run() method can execute multiple parts of logic by checking the current thread’s name or priority — helping us control different thread operations in one place efficiently. 🔹 Key Points: Helps manage multiple operations within a single block of execution. Reduces code duplication and simplifies debugging. Efficiently demonstrates how one run() method can serve multiple threads. 👉 Main Use: To perform multiple tasks concurrently and make full use of CPU cores for better performance. 💡 Summary Multithreading = Better performance + Efficient CPU utilization + Parallel execution #Java #Multithreading #Thread #JavaDeveloper #Coding #Programming #TapAcademy #JavaLearning #Concurrency

💻 Java Multithreading — Cake Baking Example 🍰 Today, I practiced multithreading in Java by simulating a cake baking process 👩🍳 Each team (thread) performs: 🧑🍳 Preparation 🥣 Mixing 🔥 Baking 🎂 Decoration All tasks run in parallel, showing how multiple threads share CPU time. Key concepts I explored: ✅ Implementing Runnable ✅ Setting thread names and priorities (MIN, NORM, MAX) ✅ Using isAlive(), join(), and sleep() ✅ Observing thread lifecycle states (NEW, RUNNABLE, TERMINATED) This small project helped me understand how synchronization and priority affect thread execution order. 🚀 Always fun to see theory come alive in code! #Java #Multithreading #CoreJava #CodingJourney #LearningByDoing #Programming Gitub Link:https://lnkd.in/grxxw5jr

Day 7 of #50DaysOfCode – Java Today I practiced arrays and conditional statements by writing a program to find the smallest number from five user inputs. 💻 What I did: Took 5 numbers from the user Stored them in an array Used a loop and if condition to find the smallest number 🧠 Concepts learned: Arrays (int[]) Loops (for) Conditional statements (if) Input/output using Scanner Step by step, getting stronger with Java! 💪 #Java #CodingJourney #LearnInPublic #Programming #50DaysOfCode

Today I read Item 4 of Effective Java. It talks about utility classes, why we should not make objects from them, and what is the best way to stop that. The good way is to make a private constructor, so nobody can create or extend the class. Very small idea, but really smart and useful. #Java #EffectiveJava #CleanCode #Programming

🚀 Exploring Java Fundamentals with a Practical Twist! Just shared a simple yet powerful Java program that identifies numbers divisible by both 3 and 5 within a user-defined range. It’s a great example of how object-oriented design and basic control structures come together to solve real-world problems. 🔍 What it does: Prompts the user for a range Iterates through numbers from 0 to that range Prints numbers divisible by both 3 and 5 💡 Whether you're just starting out or brushing up on your Java skills, this snippet is a great reminder of how clarity and logic go hand in hand in programming. #Java #Programming #ObjectOrientedDesign #CodingJourney #TechLearning #LinkedInLearning #SoftwareDevelopment

🧡Today, I learned two important OOP (Object-Oriented Programming) concepts in Java — Method Overloading and Method Overriding. Method Overloading: When multiple methods have the same name but different parameters in the same class. void show(int a, int b); void show(String name); Method Overriding: When a child class redefines a method of its parent class with the same name and parameters. class Parent{ void display(){sout ("I'm Parent class");} } class Child extends Parent{ void display(){sout ("I'm Parent class");} } Overloading → Compile-time polymorphism Overriding → Runtime polymorphism #Java #OOPs #Programming #LearningJourney #CodeNewbie #100DaysOfCode #JavaDeveloper #LinkedInLearning
