Question

初学者在这里尝试返回评论方法：

public static String comment(int score, int parForHole) {
    if (parForHole - score > 4)
        return "condor!!!!";
    if (parForHole - score == 3)
        return "albatross!!!";
    if (parForHole - score == 2)
        return "eagle!!";
    if (parForHole - score == 1)
        return "birdie!";
    if (parForHole - score == 0)
        return "par";
    if (parForHole - score == -1)
        return "bogey";
    if (parForHole - score == -2)
        return "double bogey";
    if (parForHole - score < -2)
        return "triple+ bogey";

    return "asdasd"; // Replace by a suitable switch stmt.
}

使用switch语句有类似的方法吗？我对它不太熟悉。感谢任何帮助！

Answer 1

您可以计算parForHole总分 - 得分，然后通过switch语句运行结果。

public static String comment(int score, int parForHole) {
    int total = parForHole - score;

    switch(total) {

        case 3 :
            return "albatross!!!";


        //   ... and so on


    }

    if (total > 4)
        return "condor!!!!";
    if (total <= 3)
       return "triple+ bogey!!!!";

    return "asdasd";
}

但是对于比较＆gt; 4等我猜你必须保留if语句。

Answer 2

public static String comment(int score, int parForHole) {
    String strig;
    switch(parForHole - score){
        case 1:
            string = "something";
            break;
        case 2:
            string = "something else";
            break;
        default:
            string = "default string";
            break;
    }
    return string;
}

Switch只是基本上切换到你给它的情况。如果parForHole - 得分为1，它将切换到案例1.如果parForHole - 得分给出未定义的值，则切换将使用默认情况。
