Write a function that takes in the radius as input and returns the circumference of a circle.
import java.util.*;
public class Solutions {
public static Double getCircumference(Double radius) {
return 2 * 3.14 * radius;
}
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
Double r = sc.nextDouble();
System.out.println(getCircumference(radius));
}
}
Input a string from the user. Create a new string called ‘result’ in which you will replace the letter ‘e’ in the original string with letter ‘i’.
Example :
original = “eabcdef’ ; result = “iabcdif”
