Below programs illustrate the working of set2DigitYearStart() Method of SimpleDateFormat:
Example 1:
Java
// Java code to illustrate set2DigitYearStart() methodimport java.text.*;import java.util.Calendar;public class SimpleDateFormat_Demo { public static void main(String[] args) throws InterruptedException { SimpleDateFormat dt = new SimpleDateFormat("MM/ dd/ yy"); try { Calendar cal = Calendar.getInstance(); cal.setTime(dt.parse("10/ 27/ 16")); System.out.println("The Starting Time: " + cal.getTime()); // Setting 1916 instead of 2016 // Using set2DigitYearStart() method dt.set2DigitYearStart( dt.parse("01/ 01/ 1900")); cal.setTime(dt.parse("06/ 12/ 16")); System.out.println("The New Time: " + cal.getTime()); } catch (ParseException except) { except.printStackTrace(); } }} |
Output:
The Starting Time: Thu Oct 27 00:00:00 UTC 2016 The New Time: Mon Jun 12 00:00:00 UTC 1916
