"Optimize your Java code with StringBuilder"

🚀 Multithreading in Java — Runnable Interface Approach After implementing multithreading using the Thread class, today I tried the second method: ✅ Implementing the Runnable interface 💡 Difference from previous approach: Instead of extending Thread We create a class that implements Runnable Then we pass that object to a Thread object and call start() In this example: ✅ One thread performs addition ✅ One prints numbers ✅ One prints characters Just like before: ✔ .run() → sequential execution ✔ .start() → runs independently and concurrently This method is more flexible because Java allows multiple interface implementations, but only single class inheritance — making Runnable a cleaner approach in real-world applications. ✅ I’ve attached the code screenshot below. ⬇️ #Java #Multithreading #Runnable #Threading #Programming #TapAcademy

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

🔥 Day 7 of Java Learning Series 🔥 Topic: 🧩 StringBuffer vs StringBuilder 🔹 StringBuffer (Java) Definition: A mutable sequence of characters that allows modification of strings without creating new objects. ✅ Thread-safe (synchronized), best for multi-threaded environments. 🔹 StringBuilder (Java) Definition: A mutable sequence of characters that allows modification of strings without creating new objects. ⚡ Not thread-safe, but faster, ideal for single-threaded environments. 🧠 Summary: Both allow efficient string manipulation, but choose based on thread safety vs performance. 10000 Coders #Day7 #Java #100DaysOfCode #Programming #StringBuilder #StringBuffer #JavaLearning #CodingJourney

As of Java 25, the main method no longer needs to be public or static, and it need not have a parameter of type String[] args Here are the complete rules for main methods 1. If there is more than one main method, static main methods are preferred over instance methods. 2. Methods with a String[] parameter are preferred over those with no parameters. 3. Private main methods are not considered. 4. If main is not static, the class must have a non-private no-argument constructor #Java25 #Java #Programming

As of Java 25, a main method no longer needs to be declared inside a class It implicitly declares a class whose name is derived from the source file. You cannot declare a constructor for an implicitly declared class. #Java25 #Java #Programming #ImplicitClasses

In Java 25, you don’t even need to write the class name, public static void main(String[] args), or System.out.println() anymore 😲 Just type: void main() { IO.println("Java 25 Version The Game Changer"); } …and it runs perfectly! 🚀 Java 25 is truly “The Game Changer.” 🔥 #Java #Java25 #Coding #Programming #Developer #JDK25 #Innovation #JavaUpdates

In my latest video, I’ve explained how to sort not just integers — but your custom objects (like students, names, anything!) — using Comparator, Comparable, and Lambda expressions. 📺 Watch the full breakdown here: https://lnkd.in/gkvb2VxY #Java #Programming #Coding #Comparator #Comparable #LearnJava #SoftwareDevelopment

💻 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

🚀🚀🚀Java 25 unlocks more memory for free! Every object in Java includes a metadata header used by the JVM to manage class pointers and identity hash codes. With Java 25’s *compact object headers*, this overhead drops from 12 bytes to 8 bytes—no code changes needed! Smaller objects mean less memory usage, fewer garbage collections, and faster performance. A big win for everyone ! 💪✨ #Java #Java25 #Programming #TechInnovation
