Thread: Problem with option scanner input for a switch statement

I'm just trying to create a simple switch statement structure:

SwitchStatement.java:

public class SwitchStatement {
 
	public void displayMenu() {
		System.out.println("Select a bloodtype:\n Option 1: AB-negative\n Option 2: B-negative\n Option 3: AB-positive\n"
				+ " Option 4: A-negative\n Option 5: O-negative\n Option 6: B-positive\n Option 7: A-positive\n Option 8: O-positive");
	}
 
	public String Menu() {
		Scanner menuSelect = new Scanner(System.in);
		String bloodtype;
		switch(menuSelect.NextInt()) {
		case 1:
			bloodtype = "AB-negative";
			System.out.println("You selected the " + bloodtype + " bloodtype.");
			break;		
		case 2:
			bloodtype = "B-negative";
			System.out.println("You selected the " + bloodtype + " bloodtype.");
			break;
		case 3:
			bloodtype = "AB-positive";
			System.out.println("You selected the " + bloodtype + " bloodtype.");
			break;
		case 4:
			bloodtype = "A-negative";
			System.out.println("You selected the " + bloodtype + " bloodtype.");
			break;
		case 5:
			bloodtype = "O-negative";
			System.out.println("You selected the " + bloodtype + " bloodtype.");
			break;
		case 6:
			bloodtype = "B-positive";
			System.out.println("You selected the " + bloodtype + " bloodtype.");
			break;
		case 7:
			bloodtype = "A-positive";
			System.out.println("You selected the " + bloodtype + " bloodtype.");
			break;
		case 8:
			bloodtype = "O-positive";
			System.out.println("You selected the " + bloodtype + " bloodtype.");
			break;
		default:
			System.err.println("Invalid option. Choose an option between 1 and 8.");
			break;
		}
		return bloodtype;			
	}
}

Main.java:
[CODE]

Line 15 error: "The method NextInt() is undefined for the type Scanner"

What am I missing?

+ add bloodtype initialization before return it eg in switch default:
default:
bloodtype = "";
