I have this static class called from my lightning component, but am getting the error

          Static methods need to be called like this: Class.staticMethodName() i.e. String.valueOf()



          What you're currently doing is using an instance of a string to try to call a static method, which (as the error indicates) is not allowed.



          bad:



          selqenddate.valueOf(selqenddate)


          good:



          String.valueOf(selqenddate)


          Of course, you don't need to use String.valueOf() at all here because selquarter is a string, and substringBetween() also returns a string.



          Instead, you need to be using a method that takes a String as input, and gives you a Date as output such as Date.parse()

            As the error suggests, you are trying to use a static method valueOffrom String class on an instance of a String named selqenddate, which is not allowed.



            You are most likely are trying to construct a date from a string value, and that you will need to utilize the Date.valueOf()instead. Your code should look like something as below:



            Date startdate = 
            (Date.valueOf(selqenddate))
            .addMonths(-3)
            .toStartOfMonth();


            Note, there’s no property startOfMonth on Date class.
