Example 1: python datetime string
import datetime
today = datetime.datetime.now()
date_time = today.strftime("%m/%d/%Y, %H:%M:%S")
print("date and time:",date_time)
Example 2: datetime to string python
from datetime import datetime
now = datetime.now() # current date and time
year = now.strftime("%Y")
print("year:", year)
month = now.strftime("%m")
print("month:", month)
day = now.strftime("%d")
print("day:", day)
time = now.strftime("%H:%M:%S")
print("time:", time)
date_time = now.strftime("%m/%d/%Y, %H:%M:%S")

Example 3: Java convert date to string
import java.util.Date;
import java.text.SimpleDateFormat;
public class DateToStringDemo
{
public static void main(String[] args)
{
Date dt = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
String strDate = sdf.format(dt);
System.out.println("Date format - MM/dd/yyyy to string is : " + strDate);
sdf = new SimpleDateFormat("dd-M-yyyy hh:mm:ss");
strDate = sdf.format(dt);
System.out.println("Date format - dd-M-yyyy hh:mm:ss to string is : " + strDate);
sdf = new SimpleDateFormat("dd MMMM yyyy");
strDate = sdf.format(dt);
System.out.println("Date format - dd MMMM yyyy to string is : " + strDate);
sdf = new SimpleDateFormat("dd MMMM yyyy zzzz");
strDate = sdf.format(dt);
System.out.println("Date format - dd MMMM yyyy zzzz to string is : " + strDate);
sdf = new SimpleDateFormat("E, dd MMM yyyy HH:mm:ss z");
strDate = sdf.format(dt);
System.out.println("Date format - E, dd MMM yyyy HH:mm:ss z to string is : " + strDate);
