Let us format date in mm-dd-yyyy hh:mm:ss format −// displaying date in mm-dd-yyyy hh:mm:ss format Format f = new SimpleDateFormat("mm-dd-yyyy hh:mm:ss"); String str = f.format(new Date()); System.out.println("Current Date in MM-dd-yyyy hh:mm:ss format = "+str);Since we have used the Format and SimpleDateFormat class above, therefore import the following packages. With that, we have also used the Date −import java.text.Format; import java.text.SimpleDateFormat; import java.util.Date;The following is an example −Example Live Demoimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { // displaying current date ...

Using the SimpleDateFormat(“MMM”) to display three-letter month −Format f = new SimpleDateFormat("MMM"); String strMonth = f.format(new Date()); System.out.println("Month (Three-letter format) = "+strMonth);Since, we have used the Format and SimpleDateFormat class above, therefore import the following packages. With that, we have also used the Date −import java.text.Format; import java.text.SimpleDateFormat; import java.util.Date;The following is an example −Example Live Demoimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo {    public static void main(String[] args) throws Exception {       // displaying current date and time       Calendar cal = Calendar.getInstance();       SimpleDateFormat simpleformat = new SimpleDateFormat("E, ...

Using the SimpleDateFormat(“yyyy”) to display year −// displaying year Format f = new SimpleDateFormat("yyyy"); String strYear = f.format(new Date()); System.out.println("Year = "+strYear);Since, we have used the Format and SimpleDateFormat class above, therefore import the following packages. With that, we have also used the Date −import java.text.Format; import java.text.SimpleDateFormat; import java.util.Date;The following is an example −Example Live Demoimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo {    public static void main(String[] args) throws Exception {       // displaying current date and time       Calendar cal = Calendar.getInstance();       SimpleDateFormat simpleformat = new SimpleDateFormat("E, ...

Using the SimpleDateFormat(“E, dd MMM yyyy HH:mm:ss Z”), wherein E is for Day of Week −// displaying current date and time Calendar cal = Calendar.getInstance(); SimpleDateFormat simpleformat = new SimpleDateFormat("E, dd MMM yyyy HH:mm:ss Z"); System.out.println("Today's date and time = "+simpleformat.format(cal.getTime()));Since we have used the Format and SimpleDateFormat class above, therefore import the following packages. With that, we have also used the Date −import java.text.Format; import java.text.SimpleDateFormat; import java.util.Date;The following is an example −Example Live Demoimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { ...

To display the day number, use the SimpleDateFormat('d') as shown below −Format f = new SimpleDateFormat("d"); String strDay = f.format(new Date()); System.out.println("Day Number = "+strDay);Since, we have used the Format and SimpleDateFormat class above, therefore import the following packages. With that, we have also used the Date −import java.text.Format; import java.text.SimpleDateFormat; import java.util.Date;The following is an example −Example Live Demoimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { // displaying current date and time Calendar ...

The Z means "zero hour offset", also known as "Zulu time" (UTC) in the ISO 8601 time representation. However, ACP 121 standard defines the list of military time zones and derives the "Zulu time" from theGreenwich Mean Time (GMT).Let us see the usage of SimpleDateFormat(“HH:mm:ss Z”) −Format f = new SimpleDateFormat("HH.mm.ss Z"); String strResult = f.format(new Date()); System.out.println("Time = "+strResult);The following is the complete example that displays time with offset (HH:mm:ss Z) −Example Live Demoimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { ...

The format SimpleDateFormat(“HH.mm.ss”) displays time. To work with SimpleDateFormat class, we have imported the following package.import java.text.SimpleDateFormat;Here, we are using the SimpleDateFormat class to display date and time. Let us set it for the format we want i.e time - HH.mm.ss −Format f = new SimpleDateFormat("HH.mm.ss"); String strResult = f.format(new Date()); System.out.println("Time = "+strResult);The following is an example −Example Live Demoimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { // displaying current date and time ...

The following format displays time from −hh:mm:ssThe following format displays time with AM/ PM marker −hh:mm:ss aHere, we are using the SimpleDateFormat class to display date and time. Let us set it for the format we want i.e time and AM/PM Marker −Format f = new SimpleDateFormat("hh:mm:ss a"); String strResult = f.format(new Date()); System.out.println("Time = "+strResult);The following is an example −Example Live Demoimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { // displaying current date and time ...

The Z means "zero hour offset", also known as "Zulu time" (UTC) in the ISO 8601 time representation. However, ACP 121 standard defines the list of military time zones and derives the "Zulu time" from the Greenwich Mean Time (GMT).TimeZone can be formatted in z, Z or zzzz formats.The following is an example that displays how to implement SimpleDateFormat(“Z”) −Example Live Demoimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { // displaying current date and time ...

The toString() method gives string representation to a Long. Let’s say we have the following Long object −Long longObj = new Long(70); System.out.println("Long: " + longObj);To convert it to String, the toString() method is used −String myStr = longObj.toString();The following is the complete example −Example Live Demopublic class Demo { public static void main(String[] args) { // Long Long longObj = new Long(70); System.out.println("Long: " + longObj); // conversion String myStr = longObj.toString(); System.out.println("Converted to String: " + myStr); } }OutputLong: 70 Converted to String: 70
