3. Write a Java program to create a class called "Rectangle" with width and height attributes. Calculate the area and perimeter of the rectangle

            class Rectangle
            {
               private double width;
               private double height;
            public Rectangle(double w,double h)
              {
                  width=w;
                  height=h;
               }
            void setWidth(double w)
             {
                width=w;
            }
            void setHeight(double h)
             {
                height=h;
            }   
            double getWidth()
              {
                   return width;
               }
            double getHeight()
              {
                   return height;
               }
            double calculateArea()
             {
                  return width * height;
              }
            double calculatePerimeter()
             {
                  return 2 * (width + height);
              }
            void print()
            {
                 System.out.println("Width:"+width);
                 System.out.println("Height:"+height);
                 System.out.println("Area:"+calculateArea());
                 System.out.println("Perimeter:"+calculatePerimeter());
            }
            public static void main(String st[])
              {
                  Rectangle obj=new Rectangle(22.4,7.5);
                                    obj.print();
                                      
              }
            }
            
            
        

OUTPUT

          Width:22.4
          Height:7.5
          Area:168.0
          Perimeter:59.8
