1. Design a class named **CandyBar** to represent candybars,The class contains:
+ three data member variables.The first member holds the brand **name** of a candy bar.The second member holds the **weight** (which may have a fractional part) of the candy bar, and the third member holds **the number of calories** (an integer value) in the candy bar.
+ A method named `setCandyBar()` that should prompt the user to enter each of the items to set the corresponding member variables of the CandyBay .
+ A method named `showCandyBar()` that display the information of candybar. Write a test program that creates one **CandyBar** objects and display its information.A sample
run might look like this:
``` log
Enter brand name of a Candy bar: new
Enter weight of the candy bar: 4.5
Enter calories (an integer value) in the candy bar: 230
Brand: new
Weight: 4.5
Calorie: 230
```
2. Design a class named Rectangle to represent a rectangle. The class contains:
+ Two double data fields named width and height that specify the width and height of the rectangle. The default values are 1 for both width and height .
+ A no-arg constructor that creates a default rectangle.
+ A constructor that creates a rectangle with the specified width and height .
+ A method named `getArea()` that returns the area of this rectangle.
+ A method named `getPerimeter()` that returns the perimeter.
+ A method named `display()` that print out the information of rectangle.
Write a test program that creates two Rectangle objects ,one with width 4 and height 40 , and the other with width 3.5 and height 35.9 . Display the width, height, area, and perimeter of each rectangle in this order.A sample run might look like this:
``` log
Rectangle 1
-------------
Width: 4
Height: 40
Area: 160
Perimeter: 88
Rectangle 2
-------------
Width: 3.5
Height: 35.9
Area: 125
Perimeter: 78
```
