Leniency

Leniency refers to whether or not a strict rule will be applied at parsing. If a DateFormat object is lenient, it will accept Jan 32, 2005. In fact, it will take the liberty of converting it to Feb 1, 2006. By default, a DateFormat object is lenient. import java.text.DateFormat; import java.text.ParseException; import java.util.Date; public class MainClass {   public static void main(String[] args) {     DateFormat shortDf = DateFormat.getDateInstance(DateFormat.SHORT);     DateFormat mediumDf = DateFormat.getDateInstance(DateFormat.MEDIUM);     DateFormat longDf = DateFormat.getDateInstance(DateFormat.LONG);     DateFormat fullDf = DateFormat.getDateInstance(DateFormat.FULL);     System.out.println(shortDf.format(new Date()));     System.out.println(mediumDf.format(new Date()));     System.out.println(longDf.format(new Date()));     System.out.println(fullDf.format(new Date()));     // parsing     try {       Date date = shortDf.parse("Jan 32, 2005");     } catch (ParseException e) {     }   } } 1/26/07 Jan 26, 2007 January 26, 2007 Friday, January 26, 2007
