You will write a Circle class $($can abbreviate, C$)$ with the following characteristics:

$$ Has a center that is denoted by x and y $($double$),$ a radius $($double$),$ and a color $($string$)$ that are all supplied in a constructor.

$$ A constructor that accepts all $4$ properties..

$$ A constructor that accepts a radius only. In this case the x and y should be set $0\mathrm{.}0$ each and the color set to $$orange$,$ using best practices.

$$ A constructor that accepts x and y only. In this case the radius should be set $1\mathrm{.}0$ and the color set to $$purple$,$ using best practices.

$$ A getter and setter for the radius property only. $($you do not need to write a getter and setter for the other properties; however, you can assume they exist$).$
