Java Merge Two Arrays Algorithm

Arrays in java 💫 An array is defined as a homogeneous coollection of information. An array is a linear datastructure,the advantages of using array is, 1.creating an array is simple. 2.storing the data into in array is simple. 3.the retrival of the data from an array is simple. #GRNarendrareddy #Globalquesttechnologies

Day 10- What I Learned In a Day(JAVA) In the real world, input is not inbuilt-the user has to provide it. Today, I learned how to take user input in Java and understood how the Scanner class works. I learned: ✔ Why Java does not automatically take input ✔ How System.in reads from the keyboard ✔ How nextLine() reads full user input ✔ How to create a Scanner object import java.util.Scanner; class ClassName { public static void main(String[] args) { Scanner sc = new Scanner(System.in); // input here sc.close(); } } and also using the new tool(VSCODE) practiced 👇 #Java #LearningJourney #CodingDaily #JavaDeveloper

🚀Java practice - Day 87 Completed! 👍 Problem: Sum of Squares of Special Elements Language: Java Today’s problem was about identifying special elements in a 1-indexed array. An element is considered special if its index divides the length of the array (n % i == 0). The task was to calculate the sum of the squares of such elements.✨ #Day87 #Java #LeetCode #Arrays #ProblemSolving #DailyCoding #Consistency #100DaysOfCode

A stream in java is a sequence of objects, its just a way to get data out of a collection. Collection interface in java has the stream method so all collections support stream. Arrays dont have a stream method we can make a stream out of an array by using Arrays util class's stream static method. Stream is used to process data from a collection in a declarative way much like we do chaining of array methods in JS/TS. We can have finite or infinite streams. #Java #Backend #SoftwareEngineering

Day 68 of #100DaysOfCode 🚀 Today I implemented Pascal’s Triangle using Java. At first glance, it looks like just a pattern problem. But internally, it teaches something powerful — building current state from previous state. 🔹 The first and last elements of every row are always 1 🔹 Every middle element = sum of two elements from the previous row 🔹 This is a classic example of bottom-up thinking Instead of hardcoding values, we dynamically generate each row based on the previous one. This problem strengthened: Nested loop understanding 2D List handling in Java Pattern recognition Thinking in terms of recurrence Small problems. Strong foundations. Consistent progress. On to the next one 💪 #100DaysOfCode #Java #DSA #ProblemSolving #LearningInPublic #dsawithkunal

#Day13 – Advanced Strings & Mutable vs Immutable 🤯 Today was all about Advanced String concepts and understanding Mutable vs Immutable in Java. ✔ Difference between immutable and mutable strings ✔ How concat() creates a new object in Heap ✔ How reference update changes output ✔ Difference between String, StringBuffer, and StringBuilder ✔ Initial capacity (16) and dynamic capacity formula (n * 2 + 2) ✔ Methods like length(), charAt(), toCharArray() ✔ Split vs StringTokenizer (why split is recommended) TAP Academy Harshit T #Java #Strings #StringBuilder #StringBuffer #CoreJava #ProgrammingJourney #Consistency

✅ DSA Day 8 / 100 Solved Reverse an Array on HackerRank using Java. Problem: Given an array, return the array in reverse order. Logic : - Use the built-in method Collections.reverse() -This method reverses the elements of the list directly -Then return the reversed list This problem helped me understand how arrays/lists can be manipulated easily using Java utility methods. #DSA #100DaysOfCode #Java #HackerRank #LearningInPublic #BeginnerDSA

 𝐒𝐭𝐨𝐩 𝐮𝐬𝐢𝐧𝐠 𝐢𝐟-𝐞𝐥𝐬𝐞 𝐜𝐡𝐚𝐢𝐧𝐬 𝐟𝐨𝐫 𝐒𝐭𝐫𝐢𝐧𝐠 𝐦𝐚𝐭𝐜𝐡𝐢𝐧𝐠. 🛑 Today I explored Switch Statements in Java. While if-else blocks work fine for boolean conditions, they become unreadable "spaghetti code" when checking multiple specific values like strings. 𝐓𝐡𝐞 𝐈𝐦𝐩𝐥𝐞𝐦𝐞𝐧𝐭𝐚𝐭𝐢𝐨𝐧 (𝐒𝐞𝐞 𝐯𝐢𝐝𝐞𝐨): [1.] Built a CLI tool that takes a String input (Fruit name) and returns specific data. [2.] Used a switch block to handle cases for "Apple", "Orange", etc. [3.] This approach is significantly faster to read and easier to debug than a massive else-if ladder. Simplicity is the soul of efficiency. #Java #CleanCode #SoftwareEngineering #BackendDevelopment #LearningInPublic #CodeNewbie #100DaysOfCode #SoftwareEngineering #WeMakeDevs

✨DAY-23: 💡 Understanding Functional Interfaces in Java – Made Simple with Real-Life Examples! Sometimes, the best way to understand Java concepts is to connect them with real-world scenarios. This meme perfectly explains three important functional interfaces in Java: ✅ Predicate – Just like checking an ID to verify if someone is above 21. It takes input and returns true or false. ✅ Consumer – Like receiving and eating a pizza 🍕. It takes input and performs an action, but returns nothing. ✅ Supplier – Like a warehouse worker delivering new supplies. It doesn’t take input, but it supplies data when needed. Functional interfaces are the backbone of Lambda Expressions and the Stream API in Java. When we relate them to daily life, the concepts become much easier to understand and remember. 📌 Java becomes powerful when theory meets real-world thinking! #Java #FunctionalInterfaces #Java8 #LambdaExpressions #Programming #CodingLife

🧠 Revision Day – Strengthening the Basics Again Yesterday was focused on strengthening fundamentals. ✔️ Java – Datatypes, Variables, If/else, Loops, 1D Arrays ✔️ SQL – SELECT, WHERE, AND/OR, BETWEEN, ORDER BY Instead of just reading, I rewrote examples and queries from memory. Real confidence comes from revisiting basics calmly and consistently. #Java #SQL #Consistency #LearningInPublic #BackendJourney
