How to loop through a Map in Java

🎬 “You can’t control everything… but you can suggest it.” That’s true for life — and for Java threads too. 😄 In my latest video, I explored how to guide thread execution using thread priority and the sleep() method in Java. 💡 Here’s what we discussed: Understanding thread priorities — from MIN_PRIORITY (1) to MAX_PRIORITY (10) Why setting a high priority doesn’t guarantee faster execution (it’s all up to the scheduler!) Using Thread.sleep() to pause execution and bring synchronized rhythm between threads Real-world analogy: how schedulers decide which thread gets the stage light first This simple experiment of making “Tony” and “Star” dance in sync taught me something deeper — sometimes optimization is about timing, not control.

Day 24 of #50DaysOfCode – Java 💻 Today’s challenge was to check whether a number is an Automorphic Number. An Automorphic Number is a number whose square ends with the same digits as the number itself. Examples: 5 → 25 ✔️ (ends with 5) 76 → 5776 ✔️ (ends with 76) This problem helped me understand digit comparison, modulus operations, and number patterns in Java 🔍✨ #Java #CodingChallenge #50DaysOfCode #LearnToCode #ProgrammingBasics #LogicBuilding #CodeDaily #ProblemSolving #AutomorphicNumber #JavaBeginner

Day 20 of #50DaysOfCode – Java Today’s task: Find the sum of all odd digits in a given number! 🔢 A simple yet logical exercise that helps strengthen your understanding of loops, conditionals, and digit manipulation. 💡 👉 This program takes a number as input and calculates the total of its odd digits using a while loop and the modulus operator. #Java #CodingChallenge #50DaysOfCode #LearnToCode #ProgrammingBasics #LogicBuilding #CodeEveryday #JavaProgramming

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

Day 18 of #50DaysOfCode – Java Today’s challenge: Calculate the Product of Digits in a Number! A simple yet logical problem that enhances understanding of loops and arithmetic operations 💡 📘 Example: Input → 234 Output → 24 (2 × 3 × 4 = 24) #Java #CodingChallenge #50DaysOfCode #CodeEveryday #LogicBuilding #LearnToCode #ProgrammingBasics

Deadlock in Java A Deadlock happens when two or more threads are blocked forever — waiting for each other’s resources. This usually occurs when each thread holds a lock and is waiting for another lock to be released. Example scenario: Thread A has Lock1 and waiting for Lock2 Thread B has Lock2 and waiting for Lock1 Both are stuck → this is DEADLOCK ❌ Why it happens? Because of circular dependency between threads. How to prevent it? Always acquire locks in same order Use tryLock() (ReentrantLock) Minimize synchronized blocks Avoid nested locks Conclusion Deadlocks can freeze your entire application. As developers, we must design our locking strategy carefully in multithreading to avoid such situations. #Java #Multithreading #Deadlock #ThreadLifeCycle #JavaDeveloper #LearningJourney #100DaysOfCode #TapAcademy 🚀

Week 8 || Day 2💡 Reversing words in Java — step by step! Today I practiced reversing each word in a sentence using two different approaches: 🔹 Approach 1 — With .reverse() method: Split the sentence using split(" ") to separate words. Used StringBuffer for each word and applied .reverse() directly. Joined the reversed words back with spaces. 🔹 Approach 2 — Without using .reverse(): Again split the string into words. For each word, used a for loop running from the last character to the first. Appended each character manually into a new StringBuffer. Combined the reversed words carefully, avoiding extra spaces.⚡ #Java #StringBuffer #ProgrammingLogic #JavaFullStack

Excited to share my latest mini-project: a Temperature Converter built in Java! 🌡️ It converts between Celsius and Fahrenheit using a clean ternary operator approach. Great practice for mastering conditional logic and variable handling. #Java #CodingProjects #LearnByBuilding #SoftwareDevelopment GitHub repo:https://lnkd.in/ewB8XUJn

🎯 LeetCode — Day 3 | “Longest Substring Without Repeating Characters” (Medium, Java) 💭 Ever tried remembering all your passwords without repeating any character? That’s pretty much what this problem felt like 😅 Today’s challenge tested my patience and precision — finding the longest substring without repeating characters. 🧩 Key Idea: Use a sliding window with a HashMap to track character positions. Every time a duplicate appears, move the start pointer forward ->simple, elegant, efficient! ⚡ Result: ✅ Accepted | ⏱ Runtime: 0 ms 💪 Complexity: O(n) 💡 Logic: Focus on “expanding and shrinking” the window smartly Each day’s logic builds the next day’s confidence. #LeetCode #Day3 #Java #CodingJourney #ProblemSolving #DSA #TechMindset #Motivation

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
