Why is my scanner not accepting any input after my user prompt?

I’m writing a program that assists Mars settlers in calculating the area/size of their potential house. The whole first half of the program works as intended, but for some reason when I prompt the user if they would like to input a second house, my scanner doesn’t accept any more input and the program execution ends, not allowing me to type in yes or no as a response, it just prints out the user prompt and cuts off. What am I doing wrong here?

import java.util.Scanner;

public class MartianHouses{
    public static void main(String[] args){
    /*Set up scanner & declare variables*/
    Scanner sc = new Scanner(System.in);
    double sqFt = 14.5;

    /*Receive input from user*/
    System.out.println("Enter the settler's name: ");
    String name = sc.nextLine();
    System.out.println("Enter the length of a side of the house: ");
    double s = sc.nextDouble();

    /*Calculate area of floor&roof*/
    double floorArea = 2*s*s*(1 + Math.sqrt(2));

    /*Calculate walls area*/
    double wallsArea = 8 * 12 * s;

    /*Calculate total area*/
    double totArea = (floorArea * 2) + wallsArea;

    /*Calculate floor cost*/
    double totCost = totArea * sqFt;

    /*Print results*/
    System.out.print(name + " has a house surface area of ");
    System.out.printf("%,.2f", totArea);
    System.out.print(" and a cost of $");
    System.out.printf("%,.2f", totCost);
    System.out.print(".");

    System.out.println(" Would you like to enter another house? Enter no to exit.");
    String response = sc.nextLine();
    double sqFt2 = 14.5;

    switch(response.toLowerCase()) {
        case "yes" : 
        System.out.println("Enter the settler's name: ");
        String name2 = sc.nextLine();
        System.out.println("Enter the length of a side of the house: ");
        double s2 = sc.nextDouble();

        double floorArea2 = 2*s2*s2*(1 + Math.sqrt(2));

        double wallsArea2 = 8 * 12 * s2;

        double totArea2 = (floorArea2 * 2) + wallsArea2;

        double totCost2 = totArea2 * sqFt2;

        System.out.print(name2 + " has a house surface area of ");
        System.out.printf("%,.2f", totArea2);
        System.out.print(" and a cost of $");
        System.out.printf("%,.2f", totCost2);
        System.out.print(".");
        break;

        case "no" : 
        break;
    }
        }
    }

>Solution :

When you do sc.nextDouble(), you type an input followed by a newline character (the enter button).

So the double s gets the value you entered but in your scanner buffer, you still have a newline character.

You can do this

1. After your sc.nextDouble(), do a sc.next() / sc.nextLine() to clear out the buffer.

2. Another option is to

String s = sc.nextDouble();

Then attempt to convert the s to an integer.
