Practicing adding Constructors, over write and overload the Object. On this assignment, reopen assignment 4.1 add the following to Rectangle class: 1) over right the java Default Constructor with this Rectangle(){:} 2) overload the Rectangle class with this constructor Rectangle(double length, double width ) 3) overload the public methods with following two methods: void setLength(double length){ this.length=length; } void setLength(double length, double width}{ this.length=length; this.width=width; } Hint- 1 package rectangledemo; 2 public class Rectangle { 3 private double length; 4 private double width; Rectangle() {...} 6 Rectangle (double length, double width) {...4 lines } .0 # void setLength (double length) {...3 lines } 3 void setLength (double length, double width) {...4 lines } .7 # void setWidth (double width) {...3 lines } double getLength() { 2 double getWidth() { return width; 14 } 15 double getArea() { 16 return width * length; } :8 public void display() { System.out.println("W="+ width+ " L="+length+" Area="+getArea()); } } |
