Method does not exist or incorrect signature: void ascending() from the type anon

I want to sort String values from a custom field from custom settings. I had no issues with the code but I get the error "Method does not exist or incorrect signature: void ascending() from the type anon'

Here's my code: 
public class SortNumbersFromCustomSetting {
	static Dev_Bootcamp__c value = Dev_Bootcamp__c.getInstance();
    
    static List<String> ListStringValue = new List<String>(value.Random__c.split('-'));
    
   		public static List<Integer> ascending(){
         List<Integer> ListIntValue = new List<Integer>();
            for(String str:ListStringValue){
                ListIntValue.add(Integer.valueOf(str));
            }
         ListIntValue.sort();
         Set<Integer> SetIntValue = new Set<Integer>(ListIntValue);
         List<Integer> FinalValue = new List<Integer>(SetIntValue);
         return FinalValue;
     }
    public static List<Integer> descending(){
        List<Integer> Temp = ascending();
        List<Integer> DescIntValue = new List<Integer>();
        for(Integer i = Temp.size()-1; i>=0; i--){
            DescIntValue.add(Temp.get(i));
        }
        return DescIntValue;
    }
}

Hi Sherwin,

If you are using the above class method in any other class or if your are trying to execute the above class then use the below ways:

SortNumbersFromCustomSetting.ascending();

or 

List<Integer> sortedInt = SortNumbersFromCustomSetting.ascending();


If you are directly call the method ascending() in outside of the above the class then you will get that error message.

Thanks,
