推荐答案

一个带switch case的简单函数，这样做

A simple function with switch case, do this

Public String getDateSuffix( int day) { 
        switch (day) {
            case 1: case 21: case 31:
                   return ("st");

            case 2: case 22: 
                   return ("nd");

            case 3: case 23:
                   return ("rd");

            default:
                   return ("th");
        }
}
