🚀 Accessing Static Members Using the Class Name in Java (Oop Concepts) In Java, static members are associated with the class itself, not with instances of the class. Consequently, you should always access static members using the class name, rather than an instance of the class or the `this` keyword. Using the class name clarifies that you are accessing a shared, class-level property or method. This promotes code clarity and avoids confusion about the scope of the variable or method. #oopconcepts #programming #coding #tech #learning #professional #career #development

💻 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

Hello LinkedIn! Today I learned about Exception Handling in Java, which helps in handling runtime errors and keeping the program running smoothly. 📌 What I understood: ✅ What is an Exception ✅ Using try-catch blocks ✅ The finally block ✅ Types of Exceptions (Checked & Unchecked) ✅ Importance of handling errors in a program Exception handling helps developers write robust and reliable applications by preventing unexpected program crashes. Step by step, improving my Java fundamentals and programming skills 💻🔥 Consistency + Practice = Progress 🚀 #Java #Programming #ExceptionHandling #Coding #LearningJourney #Developer

⚙️ Java Interface vs Abstract Class This is one of the most important Java OOP concepts. Key differences: Interface: • Full abstraction • No constructor • Uses implements • Supports multiple inheritance Abstract Class: • Partial abstraction • Has constructor • Uses extends • Single inheritance Use Interface for contracts. Use Abstract Class for base classes. #Java #SoftwareEngineering #OOP #Programming

💻 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

Did you know this about Java Wrapper Classes? In Java, not all objects are created equal. Some wrapper classes cache frequently used values to improve performance and reduce memory usage. This means Java may reuse existing objects instead of creating new ones — something that can even affect how == behaves! Understanding this small internal optimization can make a big difference in interviews and real-world coding.
