Program Name: Circle.java

Programmer’s Name: Johny Velasquez

Program Description: In this program, radius of circle is taken as user input in JOptionPane

(GUI userinput Dialogue). The input radius taken is in String data type. We need to convert it into 

int data type as required in question. Now, i  converted radius from int to double 

to operate on decimal values. I calculate diameter , circumfrence and area of circle and

shows results in a Message Dialog.
