    A)IsBlank – It Returns true if the specified String is white space, empty (”) or null, otherwise it returns false.
    B)IsNotBlank – It Returns true if the specified String is not white space, not empty (”) and not null, otherwise it returns false.

    Main Difference Between ISBLANK And ISNULL in Salesforce. ISBLANK determines if an expression has a value then returns TRUE if it does not. ... ISNULL determines if an expression is null (blank) then returns TRUE if it is. If the expression contains a value, then this function returns FALSE.
