Java Program For Constructor Overloading

class Box { double width; double height; double depth; // construct clone of an object Box(Box ob) { // pass object to constructor width = ob.width; height = ob.height; depth = ob.depth; } // constructor used when all dimensions specified Box(double w, double h, double d) { width = w; height = h; depth = d; } // constructor used when no dimensions specified Box() { width = -1; // use -1 to indicate height = -1; // an uninitialized depth = -1; // box } // constructor used when cube is created Box(double len) { width = height = depth = len; } // compute and return volume double volume() { return width * height * depth; } } class OverLoadConstructor { public static void main(String args[]) { // create boxes using the various constructors Box box1 = new Box(10, 20, 15); Box box2 = new Box(); Box cube = new Box(7); Box clone1 = new Box(box1); double vol; // get volume of first box vol = box1.volume(); System.out.println("Volume of box1 is " + vol); // get volume of second box vol = box2.volume(); System.out.println("Volume of box2 is " + vol); // get volume of cube vol = cube.volume(); System.out.println("Volume of cube is " + vol); // get volume of clone1 vol = clone1.volume(); System.out.println("Volume of clone1 is " + vol); box2.width=5; /*width,height,depth are default mumbers*/ box2.height=10; box2.depth=15; Box clone2 = new Box(box2); // get volume of clone1 vol = clone2.volume(); System.out.println("Volume of clone2 is " + vol); } }
