My code keeps throwing a java.util.InputMismatchException and my .txt has the right data type.

My code is below and a picture of my file.

package shape;

public class Helper {

ArrayList shapes;

System.out.print("Enter a file name: ");

fileName = input.next();

shapes = create(fileName);

display(shapes);

input.close();

}

public static ArrayList create(String fileName) throws FileNotFoundException {

ArrayList shapes = new ArrayList();

File file = new File(fileName);

Scanner inputShapeFile = new Scanner(file);

String shapeType, shapeName;

double length, width, radius, sideOne, sideTwo, sideThree;

if (!(file.exists())) {

System.out.println("The file " + file + " does not exist.");

System.exit(0);

}

while (inputShapeFile.hasNextLine()) {

shapeType = inputShapeFile.nextLine();

inputShapeFile.nextLine();

switch(shapeType) {

rectangle.setName(shapeName);

rectangle.setLength(length);

rectangle.setWidth(width);

shapes.add(rectangle);

break;

case "Circle":

Circle circle = new Circle();

shapeName = inputShapeFile.nextLine();

radius = inputShapeFile.nextDouble();

inputShapeFile.nextDouble();

circle.setName(shapeName);

}

inputShapeFile.close();
