如何在Java中向switch语句添加同义词？

int day = 1;
switch (day) {
    case 1:
    case 2:
        System.out.println("Weekday");
        break;
    case 3:
    case 4:
        System.out.println("Weekend");
        break;
    default:
        System.out.println("Invalid day");
}

public class SynonymResolver {
    public static int resolveSynonym(String synonym) {
        switch (synonym) {
            case "Monday":
            case "Mon":
                return 1;
            case "Tuesday":
            case "Tue":
                return 2;
            // 添加更多的同义词映射
            default:
                return -1; // 未知同义词返回-1
        }
    }
}

// 在其他地方使用：
String daySynonym = "Mon";
int day = SynonymResolver.resolveSynonym(daySynonym);
switch (day) {
    case 1:
    case 2:
        System.out.println("Weekday");
        break;
    // 添加更多的case语句
    default:
        System.out.println("Invalid day");
}
