Im getting an error when running the code however I have the correct output just a mismatch error. Please help I added a screenshot of the error.

import java.util.Scanner;

public class Project_31 {

public static void main(String[] args) {

// Scanner (input) Open

Scanner input = new Scanner(System.in);

// Yarn Name

String yarnName;

System.out.print("Enter the name of the yarn specified by your pattern. ");

yarnName = input.nextLine:();

// Yarn Balls

int yarnBalls;

System.out.print("Enter the number of balls of " + yarnName + " that are required. ");

yarnBalls = input.nextInt();

// Conditional Statement Positive Number

while (yarnBalls

System.out.print("The number of balls must be positive. Please re-enter. ");

yarnBalls = input.nextInt();

}

// Yarn Yards

double yarnYards;

System.out.print("Enter the number of yards per ball of " + yarnName + ". ");

yarnYards = input.nextDouble();

// Conditional Statement Positive Number

while (yarnYards

System.out.print("The number of yards must be positive. Please re-enter. ");

yarnYards = input.nextDouble();

}

// Sub Yarn Name

String subYarnName;

System.out.print("Enter the name of the substitute yarn. ");

subYarnName = input.nextLine();

// Sub Yarn Yards

double subYarnYards;

System.out.print("Enter the number of yards of " + subYarnName + ". ");

subYarnYards = input.nextDouble();

// Conditional Statement Positive Number

while (subYarnYards

System.out.print("The number of yards must be positive. Please re-enter. ");

subYarnYards = input.nextDouble();

}

// Sub Yarn Balls

int subYarnBalls;

subYarnBalls = (int) Math.ceil(((double) (yarnYards * yarnBalls) / subYarnYards));

System.out.print("You should purchase " + subYarnBalls + " balls of " + subYarnName + " instead of " + yarnBalls

+ " balls of " + yarnName + ". ");

// Scanner (input) Close

input.close();

}
