If you are using PHP you can use the in_array function. Just put all the static values in an array and see if the string is in the array using the function.

If you are using Java then I would recommend checking this thread out.


Not sure what language you're using, but you could put those values into an array, and then do a search on the array to see if the value you're matching exists anywhere in the array.


You can create an ArryList as below:

ArrayList<String> arrList = new ArrayList<String>();
arrList.add("ABC");
arrList.add("DEF");
arrList.add("FGH");
arrList.add("IJK");
arrList.add("JKL");
System.out.println(arrList.contains("AAA"))
System.out.println(arrList.contains("FGH"));

The example result:

false
true


Create a static array of strings. Also java enum is a good idea.
