Thread: I am having drouble with my java program for calculating the area and circumference of a circle

Here is the code that I wrote out:

//program that calculates the circumference and area of a circle

import java.util.Scanner;

public class circle{

public static void main(String[] args){

Scanner input= new Scanner( System.in);


double r; //declares radius
double A; //declares area
double C; //declares circumference

System.out.print("Entered the radius\n");//prompt
r=input.nextdouble();//entered the radius

A=3.14159*r*r;
C=2*3.14159*r;

System.out.printf("The value of the circumference is %d\n", C); //displays the result for the area

System.out.printf("The value of the area is %d\n", A);

}

}

And here is what is displayed in the command prompt when I compile my code:

circle.java:17: error: cannot find symbol
r.input.nextdouble();//entered the radius

symbol: method nextdouble()
location: variable input of type Scanner
1 error

What am I doing wrong

Java has many annoying features (to some). One of them it is that it is case sensitive. nextdouble() is not the same as nextDouble().
