import java.util.Scanner;

System.out.print("Enter number of bunnies: ");
int n = input.nextInt();
// validate the user input where n must not be less than 0
while (n < 0){
System.out.print("Try agian! Enter number of bunnies: ");
n = input.nextInt();
}
// call bunny method
int count = bunny(n);
//call print method
BunnyEars object = new BunnyEars();
object.print(count);

}
public void print(int count){
//print the total number of ears (count)
System.out.println("Total ears are: " + count);
