Day 63 of #100DaysOfCode – Multithreading in Java 🧵 Today, I explored Multithreading in Java — a powerful concept that allows multiple tasks to run at the same time, improving performance and responsiveness. 🔹 What is Multithreading? Multithreading means executing multiple threads simultaneously within a program. A thread is just a lightweight process that runs independently. 🔹 Why Multithreading? Faster execution Better CPU utilization Useful in games, web servers, chat apps, real-time processing 🔹 Ways to Create Threads in Java 1️⃣ Extending Thread class 2️⃣ Implementing Runnable interface 💡 Takeaway Multithreading makes programs efficient, but must be handled carefully to avoid race conditions and inconsistency. 10000 Coders Gurugubelli Vijaya Kumar #Java #Multithreading #FullStackDeveloper #Learning #CodeJourney #100DaysOfCode

🚀 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

🚀 Just built a simple Java Number Guessing Game!🎲 This simple console based game challenges the player to guess a randomly generated number within a specified range. Each guess provides hints, and the program also tracks the total number of attempts.  It is a fun way to practice Java fundamentals and improve programming logic. 💡This project helped me strengthen core Java concepts like loops, conditional statements, user input handling, and random number generation. 🔧 Features : ✔️ Random Number Generation within a specific range (1–100). ✔️ Interactive User Input using Scanner. ✔️ Loop-based Guessing System until the correct number is entered. ✔️ Count the number of attempts that user tried. ✔️ Give hints to the user for find the random number(Too High,Too Low). 🧠 Concepts Used : Basic console I/O , Random class for generating random numbers , Scanner class , do-while loop , if-else statements , Variables & counters. 🔗 GitHub Repository : https://lnkd.in/d-ght8jn #Java #JavaProject #CodingProject #LearnJava #JavaProgramming #ConsoleApp #CodePractice #JavaDeveloper #TechSkills #SoftwareEngineering #OOP #LearningByDoing #RandomNumberGenerator

🌳 Day 68 of Posting on LinkedIn LeetCode 112. Path Sum — Java Solution Today’s problem checks whether a root-to-leaf path exists in a binary tree such that the sum of the node values equals a target sum. This is a classic DFS (Depth-First Search) problem. We recursively explore left and right subtrees, subtracting the node’s value from the target at each step. When we reach a leaf node, we simply verify if the remaining sum matches the leaf’s value. ✅ Approach Use DFS recursion. At each node, subtract its value from the target sum. When a leaf node is reached, check if the remaining sum is zero. Return true if any path satisfies the condition. 🧠 Key Takeaways Classic DFS problem on binary trees Base case: checking leaf nodes Use subtraction to track required remaining sum #leetcode #leetcode112 #dsa #coding #java #binarytrees #programming #tech #interviewprep #softwareengineering #100daysofcode

Solved “Palindrome Number” in Java today. A classic problem, but always a good one for working on logic clarity and string manipulation skills. ✅ 11,511 / 11,511 test cases passed ⚡ Runtime: 6 ms (Beats 27%) 💾 Memory: Beats 89.5% The challenge: check if an integer reads the same backward and forward. The key: converting to the int to a string and using a two-pointer approach from both ends — clean, simple, and effective. Not the fastest runtime, but a small win for writing something readable, reliable, and authentic. #LeetCode #Java #Programming #StudentDeveloper #CodingJourney #KeepLearning

🔥 Day 64 of Learning Java – Multithreading Life Cycle Today, I revised how a Thread goes through different states in Java. Understanding this helps in debugging and writing efficient concurrent code. A Thread in Java does not just run and stop. It passes through multiple states like sleep and wait Life Cycle: NEW → RUNNABLE→BLOCKED / WAITING/ TIMED_WAITING → TERMINATED 🎯 Key Takeaways start() → moves thread from NEW → RUNNABLE. sleep() and wait() → move to TIMED_WAITING / WAITING. join() blocks current thread until target thread completes. After finishing execution → TERMINATED. 💡 Why is this important? Multithreading is used in high-performance applications, gaming engines, real-time systems, and backend services. Understanding thread states helps avoid: ✔ Deadlocks ✔ Unnecessary CPU usage ✔ Concurrency bugs #Java #Multithreading #ThreadLifeCycle #DailyLearning #100DaysOfCode #LinkedInLearning

🚀 Learn Java in 5 Minutes: Add Two Numbers! I just built a simple Java program that takes two numbers from the user and calculates their sum. A perfect exercise for beginners to practice variables, input, and output. Why it matters: Learn to use the Scanner class for user input ✅ Understand System.out.println() for prompts and output ✅ Build confidence before tackling bigger projects or coding challenges ✅ Sample Run: Supply a 12 Supply b 34 The sum of 12 and 34 is 46 💡 Tip: Start small. Tiny programs like this help you master the basics before moving to advanced Java concepts. You can expand it to subtraction, multiplication, or division in just a few lines. #Java #CodingForBeginners #Programming #SoftwareDevelopment #IEEEXtreme #LearnByDoing

🔒 Java Multithreading We all know synchronized lets only one thread run a block at a time. But that’s not its only job. It also fixes a hidden issue: instruction reordering. Example 👇 number = 42; ready = true; The JVM or CPU might reorder this to: ready = true; number = 42; Why? Because inside one thread, the order doesn’t matter — the CPU reorders for speed. 💥 Problem: Another thread might see ready == true but still read the old value of number. synchronized prevents this. It creates a memory barrier — forcing all updates before releasing the lock and reading fresh values when acquiring it. So it’s not just about locking. It’s about atomicity + visibility + correct ordering — the real trio of thread safety. If you enjoyed this, follow me — I’m posting one Java Multithreading concept every day in simple language.
