Here are four examples of the use of the SimpleDateFormat....

package examples;

import java.util.*;
import java.text.*;

public class SimpleDateFormatE {
public static void main(String[] args) {

System.out.println("\r\nSimpleDateFormat1: parsing a date in the format MM/dd/yy...");
SimpleDateFormat sdf1 = new SimpleDateFormat("MM/dd/yy");
try {
Date d = sdf1.parse("11/25/98", new ParsePosition(0));
StringBuffer sb = new StringBuffer();
sdf1.format(d, sb, new FieldPosition(0));
System.out.println(sb.toString());
}
catch (Exception e) {
e.printStackTrace();
}

System.out.println("\r\nSimpleDateFormat2 parsing a date in the format dd-MM-yy...");
SimpleDateFormat sdf2 = new SimpleDateFormat("dd-MMM-yy");
try {
Date d = sdf2.parse("25-NOV-98", new ParsePosition(0));
StringBuffer sb = new StringBuffer();
sdf1.format(d, sb, new FieldPosition(0));
System.out.println(sb.toString());
}
catch (Exception e) {
e.printStackTrace();
}

System.out.println("\r\nSimpleDateFormat3: Formatting a date... ");
SimpleDateFormat sdf3a = new SimpleDateFormat("dd-MMM-yy");
SimpleDateFormat sdf3b = new SimpleDateFormat("MM/dd/yyyy");
SimpleDateFormat sdf3c = new SimpleDateFormat("EEE MMM d hh:mm:ss z yyyy");
try {
Date d = new Date();

StringBuffer sb1 = new StringBuffer();
sdf3a.format(d, sb1, new FieldPosition(0));
System.out.println(sb1.toString());

StringBuffer sb2 = new StringBuffer();
sdf3b.format(d, sb2, new FieldPosition(0));
System.out.println(sb2.toString());

StringBuffer sb3 = new StringBuffer();
sdf3c.format(d, sb3, new FieldPosition(0));
System.out.println(sb3.toString());
}
catch (Exception e) {
e.printStackTrace();
}

System.out.println("\r\nSimpleDateFormat4: Formatting a date with different time zones...");
SimpleDateFormat sdf4 = new SimpleDateFormat("EEE MMM d hh:mm:ss z yyyy");
TimeZone tz = TimeZone.getTimeZone("PST");
String[] timeZoneIDs = tz.getAvailableIDs();
for (int i = 0; i < timeZoneIDs.length; i++) {
System.out.println("time zone: " + timeZoneIDs[i]);
sdf4.setTimeZone(tz = TimeZone.getTimeZone(timeZoneIDs[i]));
try {
Date d = new Date();
StringBuffer aStringBuffer = new StringBuffer();
sdf4.format(d, aStringBuffer, new FieldPosition(0));
System.out.println(aStringBuffer.toString());
}
catch (Exception e) {
e.printStackTrace();
}
}
}
