import java.util.Scanner; class Circle{ double radius; String color; Circle(){ radius=0; color="";} Circle(double radius, String color){ this.radius= radius; this.color= color;} double getArea(){ return 3.14 *radius* radius;} class HelloWorld{ public static void main (String[] args) { Scanner scan=new Scanner(System.in); Circle circle=new Circle (5.1,"green"); System.out.println(circle.getArea()); }}

Make the relevant attributes private. Then write set and get methods. get methods return the attribute value, set methods return void and take the new value as parameter.

You can link your code if you put it on sololearn playground: Go to Code/Create section, click +, select the programming language, insert your code and save. Come back to this thread, click +, Insert Code, sort for My Code Bits, select your code. You can increase the chance that somebody helps by properly indenting your code.

Setters and getters and constructors will be explained in the sololearn Java course. You can re-read the lessons as often as you like. If you need help with a code, please link this code as described above.

When printing decimals, you should use "System.out.printf("%.2f, ...) to format numbers to 2 decimal places. It would also be nice to have getters (ones that return instance variables) and setters(changing the variables) for extra security.
