A weekly Java Coding Series – program 128 StringBuilder.append() method in Java – append () is a method of StringBuilder class. It is used to add or concatenate data to an existing string without creating a new object. It is used when strings need to be concatenated repeatedly and gives better performance. It is faster than StringBuffer. It modifies the same object in memory and helps keep the code cleaner and more readable. #java #softwaredevelopment #softwareengineer #linkedincreators #skilledshraddha Program and output –

A weekly Java Coding Series – program 130 Stream.generate() method in Java Stream.generate() is a static method in the Java Stream API. It is available from Java 8. It is used to create an infinite stream of elements. It is useful when values need to be generated dynamically. Elements are created only when required. This method helps reduce traditional loop logic. #java #softwaredevelopment #softwareengineer #linkedincreators #skilledshraddha Program and output –

A weekly Java Coding Series – program 129 Optional.orElseGet() method in Java This method is part of the Optional class introduced in Java 8. It returns the value if present, otherwise it generates a default value. The method ensures that the default value is created only when the Optional is empty. This helps avoid unnecessary object creation and makes the code cleaner. #java #softwaredevelopment #softwareengineer #linkedincreators #skilledshraddha Program and output –

Java Interfaces Today I learned about Interfaces in Java. An Interface is a collection of abstract methods that defines what a class should do, but not how it should do it. By default, all methods inside an interface are public and abstract. Interfaces help developers write flexible, reusable, and maintainable code. They also support multiple inheritance, which allows a class to implement more than one interface. Understanding interfaces helps in designing better programs and improving code structure in Java. 📚 Always excited to learn new concepts and grow my programming skills! #Java #Interfaces #Programming #LearningJourney#SoftwareDevelopment #JavaDeveloper

Java 8:Optional Class! NullPointerException is one of the most common issues developers face in Java. Java 8 introduced the Optional class to help developers write safer and more readable code by explicitly handling the absence of values. In this carousel you will learn: ✔ What Optional is ✔ How to create Optional objects ✔ Common methods developers use ✔ Best practices and mistakes to avoid If you're a Java developer, mastering Optional is a must for writing clean modern Java code. Which Optional method do you use the most? Comment! #Java #JavaDeveloper #Java8 #Programming #SoftwareDevelopment #Coding #TechLearning #JavaForbeginners #JavaTipsForProfessionals

💻 Java Programming Practice – Decimal to Binary Conversion. Today I practiced a Java program to convert a Decimal number into a Binary number. 📌 What this program does: • Takes a decimal number as input from the user • Uses division by 2 logic to find binary digits • Stores the values in an array • Prints the binary number as output ✅ Example: Decimal Number: 12 Binary Number: 1100 💡 Concepts used in this program: ✔ Java input using Scanner ✔ While loop ✔ Arrays ✔ Number conversion logic I am practicing Java programs daily to improve my coding and problem-solving skills for IT placements. #Java #Programming #CodingPractice #JavaDeveloper #LearningJourney #SoftwareDevelopment

Today I revised Java Wrapper Classes and understood why they are important. Java Collections store only objects, not primitive types — so wrapper classes help convert primitives like int, double, char into objects like Integer, Double, Character. Also practiced Auto-Boxing and Auto-Unboxing, which makes conversion between primitive and object types seamless. Small concept, but very important for writing clean Java code 🚀 Saketh Kallepu Anand Kumar Buddarapu #Java #WrapperClasses #AutoBoxing #JavaCollections #LearningJourney

💻 Java Programming Practice – Reverse a String. Today I practiced a Java program to reverse a string. 📌 What this program does: • Takes a string input from the user • Reads each character from the end of the string • Builds a new reversed string • Displays the reversed output ✅ Example: Input: Tiruvannamalai Output: ialamannavuriT 💡 Concepts used in this program: ✔ Java Scanner input ✔ String length method ✔ For loop ✔ Character handling I am practicing Java programs daily to improve my coding and problem-solving skills for IT placements. #Java #Programming #CodingPractice #JavaDeveloper #Learning #SoftwareDevelopment

💻 Java Programming Practice – Count Vowels in a String. Today I practiced a Java program to count vowels in a string. 📌 What this program does: • Takes a string input from the user • Checks each character in the string • Identifies vowels (a, e, i, o, u) • Counts the total number of vowels ✅ Example: Input: RamanathapuramEducation Output: Vowels in the String = 10 💡 Concepts used in this program: ✔ Java Scanner input ✔ String methods ✔ For loop ✔ Conditional statements I am practicing Java programs daily to improve my coding and problem-solving skills for IT placements. #Java #Programming #CodingPractice #JavaDeveloper #Learning #SoftwareDevelopment

In Java, both ArrayList and Vector are classes used to store dynamic arrays (resizable arrays). But there are important differences between them. 🔹 1️⃣ Basic Introduction Java provides both ArrayList and Vector in the java.util package. Both implement the List interface. Both allow duplicate elements. Both maintain insertion order. 🔹 2️⃣ ArrayList ArrayList is not synchronized, so it is faster. ✅ Features: Not thread-safe Faster performance Introduced in Java 1.2 Increases size by 50% when full 🔹 3️⃣ Vector Vector is synchronized, so it is thread-safe. ✅ Features: Thread-safe (synchronized methods) Slower than ArrayList Legacy class (introduced in Java 1.0) Doubles its size when full Thankful to my mentor, Anand Kumar Buddarapu, and the practice sessions that continue to strengthen my core Java knowledge.
