java - 如何将java中的if-else语句更改为switch case语句

Question

我的问题是如何将 if-else 语句更改为 switch case 语句，我已经做了一些工作，它在 netbean 中包含错误:

if(result.length <= 2){
            if ((result[0].equals("UC"))||(result[0].equals("uc"))){
                fix = "UC";
            }
            else if ((result[0].equals("LC"))||(result[0].equals("lc"))){
                fix = "LC";
            }
            else
                fix = "error";  
        }else
            fix = "length";

尝试这样

switch (result[0]) {
    case "UC":
    case "uc":
        fix = "UC";
        break;
    case "LC":
    case "lc":
        fix = "LC";
        break;
    default:
        fix = "error";
}
