Write a Java program to Compute Area and Circumference with
formatting and standard I/O.
(SOURCE CODE)
import java.text.*;
import java.util.*;
class Circle
{
public static void main(String[] args)
{
double PI = 3.14159;
String TAB = "\t";
String NEWLINE = "\n";
double radius, area, circumference;
Scanner scanner = new Scanner(System.in);
DecimalFormat df = new DecimalFormat("0.000");
System.out.println("Enter radius: ");
radius = scanner.nextDouble( );
area = PI * radius * radius; //compute the area and
circumference
circumference = 2.0 * PI * radius;
System.out.println("Given Radius: " + TAB + df.format(radius)
+ NEWLINE +"Area: " + TAB + df.format(area) + NEWLINE +
"Circumference: " + TAB + df.format(circumference)); //Display the results
}
}
