• Make the following public static variables as private

      public static final String[] months = {
          "January", "February", "March", "April", "May", "June",
          "July", "August", "September", "October", "November",
          "December"

      public static final String[] days = {
          "Monday", "Tuesday", "Wednesday",
          "Thursday", "Friday", "Saturday", "Sunday"
      };
  
      public static final String[][] timevals = {
          {"1000", "millisecond"},
          {"60", "second"},
          {"60", "minute"},
          {"24", "hour"},
          {"168", "week"}
      };
  
      public static final DecimalFormat df = new DecimalFormat("0.00;-0.00");
      public static final String DATE_FORMAT = "yyyy-MM-dd";
      public static final String DATE_TIME_FORMAT = "yyyy-MM-dd HH:mm:ss.SSS";
      public static final String TIME_FORMAT = "HH:mm:ss";
  

• Add public static methods as getDateFormat(), getDateTimeFormat() and getTimeFormat() methods and use them in following classes;

      DateTimeConverters.java
      UelFunctions.java
      CommonWidgetModels.java
      ModelFormField.java
      SetCalendar.java
      EbayStoreAutoPreferences.java
