Java Strings Fundamentals and Manipulation

📘 Day 13 | Java Learning – Strings Today I explored one of the most important topics in Java — Strings. I learned how strings work internally, how they are stored in memory, and how different methods help in comparing and manipulating them efficiently. 📌 Key Concepts Covered: 🔹 Strings as a collection of characters enclosed in double quotes 🔹 Types of Strings:   • Immutable (cannot be changed)   • Mutable (can be modified) 🔍 String Comparison Methods: ✔ == ✔ equals() ✔ compareTo() ✔ equalsIgnoreCase() 🔗 String Operations: ✔ String concatenation ✔ Understanding String memory in the Heap 💻 Programs Practiced: ✅ Printing a string ✅ Reversing a string ✅ Reversing a string using logic ✅ Checking whether a string is a palindrome ✅ Comparing complete strings using equals() ✅ Comparing characters using == ✅ Counting spaces in a string ✅ Counting words in a string ✅ Counting vowels using if condition ✅ Printing consonants in a string 📈 Learning something new every day and growing step by step! #Java #CoreJava #StringsInJava #JavaLearning #CodingJourney #Programming #TAPAcademy #LearningEveryDay #StudentDeveloper

📘 Day 9 | Core Java Series Operators are the building blocks of every Java program. This visual explains the 4 most important types: 👉 Arithmetic 👉 Relational 👉 Logical 👉 Assignment If you remember just this: Arithmetic → Calculate Relational → Compare Logical → Combine Assignment → Store Everything else becomes easier. 📌 Save this for revision 💬 Feedback or corrections are welcome #Java #CoreJava #LearningInPublic #JavaBasics #Programming

☕ Strings in Java – Basics You Should Know In Java, a String is an object used to store a sequence of characters. Strings are immutable, which means once created, their value cannot be changed. ✔ Stored in String Constant Pool ✔ Provides many built-in methods ✔ Helps in secure and efficient data handling String immutability improves performance and security in Java. #Java #Programming #Coding #TapAcademy #Strings #OOP #SoftwareDevelopment #Learning #Developer TAP Academy Sharath R
