I'm trying to call the variable r from another class, but I'm having trouble making it.

public class Circle {
    
    final double PI = 3.14159;
    CircleTester temp = new CircleTester();
    double radius = temp.gettemprad();  //this is where i was gonna call a method but I was having trouble making one in my other class
    
    Circle(double newradius){
        newradius = radius;
    }
    Circle(){
        radius = 0.0;
    }
    void setRadius(double inputradius){
        radius = inputradius;
    }
    double getRadius(){
        return radius;
    }
    
    double getArea(){
       return PI * radius * radius;
    }
    
   double getDiameter(){
       return radius * 2;
    }
   double getCircumference(){
       return 2 * PI * radius;
   }
}

import java.util.Scanner;
public class CircleTester {
    public static void main(String [] args){
       double r;
       Circle c = new Circle();
        Scanner scan = new Scanner(System.in);
        
        System.out.println("What is the radius of the circle");
        
        r = scan.nextDouble();
        
        //after I got r to the other class i was going to call the methods below
                
        System.out.println("The circle's area is "+c.getArea());
        
        System.out.println("The circle's diameter is "+c.getDiameter());
        
        System.out.println("The circumference is "+c.getCircumference());
    
    }
    
}

Basically I want the user input (r) to go to the other class so I can get different measurements from it and then return those values back to the original class using System.out.print. Thanks.
