Checking Java Anagrams with String Manipulation

Today I Learned Operators in Java Understanding operators is essential for writing efficient and logical Java programs. Operators allow us to perform operations on variables and values, making them a core building block of programming. --> Types of Operators in Java 1. Arithmetic Operators Used for mathematical calculations Example: + - * / % 2. Relational Operators Used to compare two values and return a boolean result (true or false) Example: == != > < >= <= 3. Logical Operators Used to combine multiple conditions Example: && || ! 4. Assignment Operators Used to assign values to variables Example: = += -= *= /= %= 5. Unary Operators Operate on a single operand Example: ++ -- ! 6. Ternary Operator A shorthand form of the if-else statement Example: int max = (a > b) ? a : b; Key Takeaways --> Operators help perform computations and decision-making in programs --> Relational operators always return a boolean value --> The ternary operator simplifies conditional logic --> Understanding operators improves code readability and efficiency -->Currently strengthening my Java fundamentals as part of my learning journey in software development. #Java #JavaProgramming #LearnJava #JavaDeveloper #ProgrammingBasics #Coding #SoftwareDevelopment #Developers #TechLearning #CodeNewbie #JavaConcepts #ProgrammingJourney

🚀 Day 25 / 30 – Java Learning Journey Today I explored Queue and Deque in Java from the Java Collections Framework. 🔹 Queue Interface A Queue follows the FIFO (First In First Out) principle where elements are inserted at the rear and removed from the front. Key methods: • add() / offer() → insert element • remove() / poll() → remove element • element() / peek() → access the head element 🔹 Implementations of Queue • Hash-based and linked structures like LinkedList • Priority-based queues using PriorityQueue • Double-ended structures like ArrayDeque 🔹 Deque (Double Ended Queue) Deque allows insertion and deletion from both the front and rear. Important methods: • addFirst(), addLast() • removeFirst(), removeLast() • peekFirst(), peekLast() 🔹 PriorityQueue Elements are ordered by priority (default uses min-heap), where the smallest element is always at the head. 🔹 ArrayDeque A resizable array implementation of Deque that is usually faster than LinkedList for queue operations. 💡 Applications • Task scheduling • BFS algorithm in graphs • Printer queue • Top K elements problems Day 25 complete ✔️ Continuing the journey of mastering Java step by step. #Java #JavaCollections #Queue #Deque #JavaLearning #30DaysOfJava

🚀 Day 13 of My Java Journey Today I explored Java Keywords — the building blocks of Java programming 💻 🔑 Key Learnings: • Java has 53 reserved keywords • Keywords are predefined & cannot be used as identifiers • All keywords are written in lowercase • Learned categories: 👉 Program Control (if, else, for, while...) 👉 OOP Concepts (class, interface, extends...) 👉 Miscellaneous (import, package, this...) 💡 Interesting Fact: "true", "false", and "null" are reserved literals, not keywords! ⚠️ Bonus Tip: Keywords like "goto" and "const" are reserved but not used in Java Aman Soni 📌 Understanding keywords is the first step to mastering Java syntax and logic. #Java #Programming #CodingJourney #100DaysOfCode #JavaDeveloper #Learning #Tech #Beginners #CodeNewbie #DeveloperJourney

📘 Toggle Case in a String Using Java | String Manipulation Practice Continuing my Java programming and problem-solving journey, I implemented a program to toggle the case of characters in a string. The program converts uppercase letters to lowercase and lowercase letters to uppercase, while keeping digits unchanged. This helped me practice character handling and string traversal in Java. 🔎 What this implementation demonstrates: ✅ Taking string input from the user using Scanner ✅ Iterating through each character of a string ✅ Identifying uppercase letters, lowercase letters, and digits ✅ Converting case using Java Character class methods ✅ Keeping numeric characters unchanged 💻 Key Concepts Practiced: ✔ Java String handling ✔ Character classification using Character.isUpperCase() and Character.isDigit() ✔ Case conversion using Character.toUpperCase() and Character.toLowerCase() ✔ Looping through characters using charAt() 📌 Example Execution Input: hell2Jio7WellDeserve54ByE Output after toggling case: HELL2jIO7wELLdESERVE54bYe 🔎 Important Learning Moment: While implementing this program, I learned how Java’s Character utility methods help efficiently process and manipulate text data. 🚀 Step by step, continuing to strengthen my Java fundamentals, problem-solving skills, and DSA concepts. #Java #Programming #CodingPractice #StringManipulation #DSA #LearningJourney #StudentDeveloper #JavaProgramming

DAY 30: CORE JAVA 🚀 Understanding "this()" vs "super()" in Java – A Quick Guide! While working with constructors in Java, two important calls often come into play: "this()" and "super()". Though they may seem similar, they serve very different purposes. 🔹 "this()" Call - Used to achieve constructor chaining within the same class. - Helps reuse constructors in a clean and efficient way. - It is optional and depends on the programmer’s need. 🔹 "super()" Call - Used to achieve constructor chaining between parent and child classes. - It is automatically invoked by Java (default behavior). - Always placed on the first line of the child class constructor. ⚠️ Important Rule 👉 "this()" and "super()" cannot be used together in the same constructor, as both must be the first statement. 💡 Key Insight Subclass variables always have higher priority than superclass variables. To access parent class variables when both have the same name, we use "super". 📌 Mastering these concepts is essential for writing clean and efficient code using inheritance in Java.

While learning core Java concepts, I recently explored the Collection Hierarchy, and it gave me a clearer understanding of how Java manages and organizes groups of objects efficiently. The Java Collection Framework provides a set of interfaces and classes designed to store, retrieve, and manipulate data in different ways depending on the requirement. 🔹 List – Maintains insertion order and allows duplicate elements. Examples: ArrayList, LinkedList, Vector, Stack. 🔹 Set – Stores only unique elements and prevents duplication. Examples: HashSet, LinkedHashSet, TreeSet. 🔹 Queue – Designed for processing elements typically in FIFO (First In First Out) order. Examples: PriorityQueue, ArrayDeque. Understanding this hierarchy helps developers choose the right data structure based on ordering, uniqueness, and performance requirements. #Java #JavaCollections #SoftwareDevelopment #JavaDeveloper #Programming #Learning

🚀 Mastering Java Switch Statements – From Basic to Advanced I recently practiced different ways of using switch statements in Java, and here’s what I learned step-by-step 👇 🔹 1. Traditional Switch (Basic) ➡️ Used multiple case blocks with break statements ➡️ Works but repetitive and lengthy 🔹 2. Grouping Cases ➡️ Combined multiple cases using commas ➡️ Cleaner and reduces duplication 🔹 3. Switch with Arrow (->) ➡️ Introduced modern syntax ➡️ No need for break ➡️ More readable and concise 🔹 4. Using Variable for Output ➡️ Stored result in a variable ➡️ Better for structured and reusable code 🔹 5. Switch as Expression ➡️ Directly returns value ➡️ Makes code shorter and powerful 🔹 6. Using yield Keyword ➡️ Used in block-style switch expressions ➡️ Helps return values explicitly ➡️ Converted output to uppercase for better formatting ✨ Key Takeaways: ✔ Code readability improved step by step ✔ Reduced redundancy ✔ Learned modern Java features ✔ Understood difference between statement vs expression 🙏 Grateful for the Guidance: A special thanks to my mentor Anand Kumar Buddarapu sir for guiding me and encouraging me to explore Java pattern programming and logical coding techniques.

🚀 Day 25 of My Java Learning Journey Today I learned about the Object Class in Java and its important methods. 🔹 The Object class is the parent of all classes in Java. 🔹 toString() is used to convert an object into a readable string format. 🔹 clone() is used to create a copy of an object. 🔹 Java is not a purely object-oriented language because it uses primitive data types like int, char, and float. 🔹 Wrapper classes such as Integer, Double, and Character help convert primitive types into objects. Example: Employee e = new Employee(); System.out.println(e); Internally, Java calls: e.toString(); Every day I am improving my Java skills step by step 💪 Consistency + Practice = Growth 📈 #Java #ObjectOrientedProgramming #Programming #LearningJourney #100DaysOfCode #SoftwareDevelopment
