We would like to calculate the circle area.
Code structure you can use:
public class Main { public static void main(String[] args) { double radius; // Declare radius double area; // Declare area // Assign a radius radius = 20; // New value is radius /*from www .j a v a2s .c om*/ //your code here } }
public class Main { public static void main(String[] args) { double radius; // Declare radius double area; // Declare area // Assign a radius radius = 20; // New value is radius // Compute area area = radius * radius * 3.14159; // Display results System.out.println("The area for the circle of radius " + radius + " is " + area); } }
