java - Setting DateTime to Certain Value -

I am using joda to compare an array of stars. My goal is to go through the array and see what the dates are missing. I am planning to complete this by specifying the first variable in the array for a DateTime variable, then the array and date time to calculate. If the date time is equal to array [x] , then both the datetime and the array increases by one if not the date time array (Which means that a date is missing) DateTime will increase by one and as long as date time is equal to array [x] . At the moment, I'm just trying to get it so that the first date (on holder [2]) is the value of the date before the date date.

My question is how do I create it so that I can assign date first date to holder [2] ? Assigning an holder [2] to first date is returning an error.

  DateTime first date = new date (time); DateTime Formator DTF = DateTime FormatPartin ("YEMEMMDD"); String date = dtf.print (first date); String fake; While ((Fake = Reader. Readline ()) = Faucet {String [] Holder = Fake Split (""); First Data = Holder [2]; // ****** Problem ****** System.out.printlain (first paid); }   
 Important things about my code:  
 
 
 I am using a  BufferedReader  (20 GB) then I am reading from the line text file line (and the date of each line is  holder [2] )  
 
 The format of the date on the text file is in yyyymmdd and I want to compare that string with the string of the  DateTime  (This is the first thing I need to do is change its first value  Dat Array for eTime  which forms my question).   
 
 I have set the right set at the right time     
 
 
 If you have a  holder [2] , the date format is represented by the string "yyyyMMDD", then you need to define the formatter that you define Do:  
  firstDate = dtf.parseDateTime (holder [2]);
