Answer 1

I think this can do what you want:

public class Base {
    public static void main(String[] args) {
    for (int i = 1; i < 31; i++) {
        System.out.println(i + getOrdinalFor(i));
    }
    }

    public static String getOrdinalFor(int value) {
        int tenRemainder = value % 10;
     if (value == 11 || value == 12 || value == 13) {
        return "th";
     }
     switch (tenRemainder) {
     case 1:
        return "st";
     case 2:
        return "nd";
     case 3:
        return "rd";
     default:
        return "th";
     }
 }
}

Answer 2

check this first where you are using.

if(value <=30){
   getOrdinalFor(value)
}else{
  return "st";
}

here is your core logic

public static String getOrdinalFor(int value) {
 int tenRemainder = value % 20;

 switch (tenRemainder) {
 case 1:
    return "st";
 case 2:
    return "nd";
 case 3:
    return "rd";
 default:
    return "th";
 }
}
