ArrayList Capacity vs Size 📦 ArrayList Size vs Capacity – Not the Same! Many developers think size = capacity. 🔹 Size → Number of elements actually present 🔹 Capacity → Internal array length Example: ArrayList<String> list = new ArrayList<>(10); 👉 Size = 0 👉 Capacity = 10 When size exceeds capacity → resizing happens. ⚠ Frequent resizing = performance cost. #Java #ArrayList #CollectionsFramework #BackendDevelopment #SoftwareEngineering #JavaDeveloper #Programming #TechTips #PerformanceOptimization #day43ofJavaandSpringboot

String vs StringBuilder Both store text. But performance is the difference. String • Immutable • Every change creates a new object StringBuilder • Mutable • Changes happen in the same object Example: String s = "Hello"; s = s + " World"; // new object created StringBuilder sb = new StringBuilder("Hello"); sb.append(" World"); // same object 📌 Use StringBuilder in loops Small optimization. Huge performance impact. #Java #CodingTips #SoftwareDevelopment #Programming

Day 31- What I Learned In a Day(JAVA) Today, I learned about nested for loops and how they are used in pattern programming. A nested loop is simply a loop inside another loop. The outer loop controls the number of rows, while the inner loop controls what gets printed in each row (columns). 🔹 Outer loop → runs row by row 🔹 Inner loop → runs completely for each row 🔹 This helps in creating patterns like squares, triangles, and pyramids For every single iteration of the outer loop, the inner loop executes fully this is the key idea behind pattern problems. Understanding this concept improved my ability to break down problems step by step and visualize output clearly. I Practiced 16 Patterns 👇 #Java #Programming #Coding #LearningJourney #NestedLoops #PatternProgramming

Removing Elements from ArrayList Removing Elements from ArrayList – Do It Correctly Many developers write: for(String s : list) { list.remove(s); // ❌ Wrong } This throws: 👉 ConcurrentModificationException Because ArrayList iterator is fail-fast. Correct ways: ✔ Use Iterator: Iterator<String> it = list.iterator(); while(it.hasNext()) { it.remove(); } #Java #ArrayList #CollectionsFramework #BackendDevelopment #Programming #JavaDeveloper #CleanCode #SoftwareEngineering #TechGrowth #SpringBoot #day45ofJavaandSpringboot
