Java Concepts I’m Mastering – Part 4: Constructor vs Method Continuing my Java fundamentals journey. Today’s focus: Constructor vs Method — a concept that looks simple but defines how objects behave. What is a Constructor? A constructor is a special block of code that: Has the same name as the class Is called automatically when an object is created Initializes object data class Student { String name; Student(String name) { this.name = name; } } It runs when: Student s1 = new Student("Kanishka"); What is a Method? A method: Has a return type Is called explicitly Performs actions class Student { String name; void display() { System.out.println(name); } } It runs only when you call it: s1.display(); Key Differences Constructor Method Same name as class Any name No return type Must have return type Called automatically Called manually Initializes object Performs operations What I Learned Constructors build the object. Methods define its behavior. Clean class design depends on understanding
