Java 为什么不是'；这个开关不工作吗？

我正在编写一些代码来计算层次结构的特定估值（以点为单位）。我将switch语句与scanner（声明为静态变量）一起使用，由于某种原因，在每个boardtype中，“y”和“n”的情况不会中断；他们只是进入下一个木板箱。我做错了什么

System.out.println("Are they on board? (y/n)");
isOnBoard = s.nextLine();
switch (isOnBoard){
case "y":
    System.out.println("Chapter, regional, or international board? ");
    boardType = s.nextLine();
    switch (boardType){
    case "chapter":
        System.out.println("Are they chapter president? (y/n)");
        switch(s.nextLine()){
        case "y":
            totalPoints = chapterPres;
            break;
        case "n":
            totalPoints = chapterBoardMember;
            break;
        }
    case "regional":
        System.out.println("Are they regional president? (y/n)");
        switch(s.nextLine()){
        case "y":
            totalPoints = regionalPres;
            break;
        case "n":
            totalPoints = regionalExecutive;
            break;
        }
    case "international":
        System.out.println("Are they international president? (y/n)");
        switch(s.nextLine()){
        case "y":
            totalPoints = internationalPres;
            break;
        case "n":
            totalPoints = internationalExecutive;
            break;
        }
    case "n": break;
}
