Java SimpleDateFormat - Constructors\n\n\n\nThere are four constructors that you can use so as to create a java.text.SimpleDateFormat.\n\n\n\n\nSimpleDateFormat()The simplest constructor which creates a java.text.SimpleDateFormat with a default pattern of date and a default locale.\n\n\n\nSimpleDateFormat(String pattern)The constructor which creates a java.text.SimpleDateFormat with a given pattern and a default locale.\n\n\n\nSimpleDateFormat(String pattern, DateFormatSymbols formatSymbols)Constructs a java.text.SimpleDateFormat with the given pattern and specific date format symbols. DateFormatSymbols is a class for encapsulating localizable date-time formatting data, such as the names of the months, the names of the days of the week, and the time zone data.\n\n\n\nSimpleDateFormat(String pattern, Locale locale)Constructs a java.text.SimpleDateFormat with the given pattern and a specific locale.\n\n\n\n\n2.

Example of SimpleDateFormat\n\n\n\nCreate a java class named SimpleDateFormatExample.java with the following code:\n\n\n\nSimpleDateFormatExample.java\n\n\n\n\n\n\n\n\n\n01\n02\n03\n04\n05\n06\n07\n08\n09\n10\n11\n12\n13\n14\n15\n16\n17\n18\n19\n20\n21\n22\n23\n24\n25\n26\n27\n28\n29\n30\n31\n32\n33\n34\n35\n36\n37\n38\n39\n40\n41\n42\n43\n44\n45\n46\n47\n48\n49\n\n\n\npackage com.javacodegeeks.corejava.text;\n \nimport java.text.ParseException;\nimport java.text.SimpleDateFormat;\nimport java.util.Date;\nimport java.util.Locale;\n \npublic class SimpleDateFormatExample {\n    public static void main(String[] args) {\n \n        Date curDate = new Date();\n \n        SimpleDateFormat format = new SimpleDateFormat();\n        String DateToStr = format.format(curDate);\n        System.out.println(\"Default pattern: \" + DateToStr);\n \n        format = new SimpleDateFormat(\"yyyy\/MM\/dd\");\n        DateToStr = format.format(curDate);\n        System.out.println(DateToStr);\n \n        format = new SimpleDateFormat(\"dd-M-yyyy hh:mm:ss\");\n        DateToStr = format.format(curDate);\n        System.out.println(DateToStr);\n \n        format = new SimpleDateFormat(\"dd MMMM yyyy zzzz\", Locale.ENGLISH);\n        DateToStr = format.format(curDate);\n        System.out.println(DateToStr);\n \n        format = new SimpleDateFormat(\"MMMM dd HH:mm:ss zzzz yyyy\",\n                Locale.ITALIAN);\n        DateToStr = format.format(curDate);\n        System.out.println(DateToStr);\n \n        format = new SimpleDateFormat(\"E, dd MMM yyyy HH:mm:ss z\");\n        DateToStr = format.format(curDate);\n        System.out.println(DateToStr);\n \n        format = new SimpleDateFormat(\"EEEEE dd MMMMM yyyy HH:mm:ss.SSSZ\", new Locale(\"el\", \"GR\"));\n        DateToStr = format.format(curDate);\n        System.out.println(DateToStr);\n \n        try {\n            Date strToDate = format.parse(DateToStr);\n            System.out.println(strToDate);\n        } catch (ParseException e) {\n            e.printStackTrace();\n        }\n    }\n}\n\n\n\n\n\n\n\n\n\n\nLet's explain the different formats of SimpleDateFormat class in the above code. Firstly, we create a Date object which is initialized with the current date and time. Then, we create different date formatters with different patterns, such as:\n\n\n\n\nThe default pattern, which shows the date in the form of month\/day\/year and the time using the 12-hour clock.\n\n\n\nyyyy\/MM\/dd, which shows the date in the form of year\/month\/day. As we can observe, the pattern for the year has 4 letters, which means that the full form of the year will be used (e.g. 2014). Otherwise a short or abbreviated form is used if available.\n\n\n\ndd-M-yyyy hh:mm:ss, which shows the date in the form of date-month-year (the month will be shown in the abbreviated form, as it has only one letter and not two as in the previous case) and futhermore, it shows the time (hour, minutes and seconds) while the hour is in am\/pm format.\n\n\n\ndd MMMM yyyy zzzz, which shows the date and the timezone in full format. We can observe that we also defined the locale of the date\/time: Locale.ENGLISH or Locale.ITALIAN below.\n\n\n\nE, dd MMM yyyy HH:mm:ss z, which shows the date, the day name of the week and the time (we can see that the hour is in capital, which means that the hour's values here are between 0 - 23, as we use the 24-hour clock).\n\n\n\nEEEEE dd MMMMM yyyy HH:mm:ss.SSSZ, which shows the day name, date, name of the month, year, 24H clock with seconds and 3 digits of milliseconds  and timezone.\n\n\n\n\nYou may notice that there is a slight but basic difference to the followings:\n\n\n\n\nmm: representes the minutes.\n\n\n\nMM: represents the Month.\n\n\n\ndd: represents the day.\n\n\n\nDD: represents the day in year (e.g. 189 out of 365).\n\n\n\nhh: represents the hour's value using the 12-hour clock.\n\n\n\nHH: represents the hour's value using the 24-hour clock.\n\n\n\n\nUsing all those formatters, we format dates as strings.\n\n\n\nFinally, we show a reverse example, where we parse a string into date, using the parse() method.\n\n\n\nIf we run the above code, we will have the following results:\n\n\n\nOutput\n\n\n\n\n\n\n\n\n\n1\n2\n3\n4\n5\n6\n7\n8\n\n\n\nDefault pattern: 7\/2\/14 11:48 PM\n2014\/07\/02\n02-7-2014 11:48:37\n02 July 2014 Eastern European Summer Time\nluglio 02 23:48:37 Ora estiva dell'Europa orientale 2014\nWed, 02 Jul 2014 23:48:37 EEST\nWed Jul 02 23:48:37 EEST 2014\n\u03a4\u03c1\u03af\u03c4\u03b7 22 \u0399\u03b1\u03bd\u03bf\u03c5\u03b1\u03c1\u03af\u03bf\u03c5 2019 22:33:46.896+0200\n\n\n\n\n\n\n\n\n\n\n5.
