How do I get today's date to print to the console in Java (2018)? [on hold]

I know this question has been asked a lot, but I've tested code from hundreds of posts about this, and none of it is working for me.

I want to print something like this:

Today's date is: 07/29/2018
Day of Week: Sunday

Here is the code I am currently testing:

package javaDemo;

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

public class TodaysDate {

public static void main(Stringargs) {

System.out.println("Today's date is: "+DateTimeFormatter.ofPattern("MM/dd/yyyy").format(LocalDateTime.now()) + " Day of Week: "+LocalDateTime.now().getDayOfWeek());


}


}

Try with this if you use java8:

java8

System.out.println("Today's date is: "+DateTimeFormatter.ofPattern("MM/dd/yyyy").format(LocalDateTime.now()) + " Day of Week: "+LocalDateTime.now().getDayOfWeek());


if you use lower version of java8

java8

String finalDay={"SUNDAY","MONDAY","TUESDAY","WEDNESDAY","THURSDAY","FRIDAY","SATURDAY"};
Calendar c = Calendar.getInstance();
c.setTime(new Date());
int dayOfWeek = c.get(Calendar.DAY_OF_WEEK);
System.out.println("Today's date is: "+new SimpleDateFormat("MM/dd/yyyy").format(System.currentTimeMillis()) + " Day of Week: "+ finalDay[dayOfWeek]);


LocalDateTime is not a moment

LocalDateTime

Never use LocalDateTime when representing a moment. Lacking any concept of time zone or offset, this class represents potential moments along a range of about 26-27 hours, the range of time zones around the world.

LocalDateTime

For a moment, use Instant, OffsetDateTime, or ZonedDateTime.

Instant

OffsetDateTime

ZonedDateTime

Time zone

Specify a time zone. For any given moment, the date varies around the globe by zone.

ZoneId z = ZoneId.of( "Africa/Tunis" ) ;
LocalDate ld = LocalDate.now( z ) ;


If you need the time-of-day as well, use ZonedDateTime.

ZonedDateTime

ZonedDateTime zdt = ZonedDateTime.now( z ) ;


Generating strings

Specify the formatting pattern.

DateTimeFormatter f = DateTimeFormatter.ofPattern( "MM/dd/uuuu" , Locale.US ) ;
String output = ld.format( f ) ;


Use DayOfWeek enum. Call getDisplayName to automatically localize the name of the day of the week.

DayOfWeek

getDisplayName

DayOfWeek dow = ld.getDayOfWeek() ;
String output = dow.getDisplayName( TextStyle.FULL , Locale.US ) ;
