@Amit, Thanks for the code snippet. However, there's this one minor correction. In the if statements, instead of "!=", it should be "==".
Thanks again.

Best response saved me a lot of extra thinking, though I approached the problem using Switch cases, which shouldn't be a big of a difference, here is my snippet:

 

public static String castTypeToString(Schema.DisplayType inputType){
        System.debug(inputType);
        switch on inputType{
            when STRING{
                return 'STRING';
            }
            when BOOLEAN{
                return 'CHECKBOX';
            }
            when PICKLIST{
                return 'PICKLIST';
            }
            When INTEGER{
                return 'INTEGER';
            }
            When DOUBLE{
                return 'DOUBLE';
            }
            When PERCENT{
                return 'PERCENT';
            }
            When ID{
                return 'ID';
            }
            When DATE{
                return 'DATE';
            }
            When DATETIME{
                return 'DATETIME';
            }
            When TIME{
                return 'TIME';
            }
            When URL{
                return 'URL';
            }
            When EMAIL{
                return 'EMAIL';
            }
            When PHONE{
                return 'PHONE';
            }
            When LONG{
                return 'LONG';
            }
            When MULTIPICKLIST{
                return 'MULTIPICKLIST';
            }
            When ENCRYPTEDSTRING{
                return 'ENCRYPTEDSTRING';
            }
            when else{
                return '';
            }
        }
    }
