Constructor overloading in Java allows a class to have multiple constructors with different parameter lists, enabling objects to be initialized in various ways.
Example: Constructor Overloading in a Box Class
class Box {double width, height, depth;// Constructor with three parametersBox(double w, double h, double d) {width = w;height = h;depth = d;}// Default constructorBox() {width = height = depth = 0;}// Constructor for a cubeBox(double len) {width = height = depth = len;}// Method to calculate volumedouble volume() {return width * height * depth;}}public class Test {public static void main(String[] args) {Box box1 = new Box(10, 20, 15); // Calls constructor with three parametersBox box2 = new Box(); // Calls default constructorBox cube = new Box(7); // Calls constructor for a cubeSystem.out.println("Volume of box1: " + box1.volume());System.out.println("Volume of box2: " + box2.volume());System.out.println("Volume of cube: " + cube.volume());}}コピーしました。✕コピーOutput:
