🚀 Day 30 of My Automation Journey – Java Strings (Package, Memory, Limitations & Real-Time Usage) - part 2

When learning Java, most people understand what a String is , but very few understand: 👉 Which package it belongs to 👉 Why it has limitations 👉 How Java overcomes those limitations 👉 Memory behaviour of Strings 👉 Real-time usage in projects Let’s break everything down in a simple and practical way 👇 📦 1. Which Package Does String Belong To? 👉 The String class belongs to: java . lang . String Important Points: java.lang package is imported by default So you don’t need to write: import java.lang.String ; 👉 That’s why we directly use: String name = "Bala" ; 🧱 2. What Type of Class is String? 👉 String is a: Final class ❌ (cannot be inherited) Immutable class 🔒 (cannot be changed) public final class String Why final? 👉 For security and consistency ⚠️ 3. Demerits of String in Java Even though String is powerful, it has some drawbacks: ❌ 1. Immutable (Cannot Modify) String s = "Hello" ; s = s + " World" ; 👉 Creates new object every time ❌ 2. Memory Consumption Too many modifications → too man
