This Java code demonstrates the use of the Calendar class and formatted output with the System.out.printf method. Here's what the code does step by step:

1. Create a Calendar instance:

   Calendar cal = Calendar.getInstance();
   

   • Calendar.getInstance() creates a calendar object set to the current date and time based on the system's default locale and time zone.

2. Print the current date and time:

   System.out.printf("The current date and time is: %tc\n\n", cal);
   

   • The %tc format specifier formats the Calendar instance (cal) or a Date object into a string that represents the complete date and time in the default format.

3. Set a specific date and time in the calendar:

   cal.set(1956, 9, 8, 5, 30, 12);
   

   • Set the calendar to a specific date and time: October (Java months are zero-indexed, so 9 represents October), 8th, 1956, at 05:30:12.

4. Create a string containing a name:

   String name = "Hitesh R. Pulimi";
   

5. Print another formatted output:

   System.out.printf(
       "My name is %s.\nI was born at %Tr on a %tA,\nthe %teth ", 
       name, cal, cal, cal
   );
   

   • My name is %s.: %s inserts the name string.
   • I was born at %Tr: %Tr formats the time (hour, minute, second) of the Calendar instance.
   • on a %tA: %tA outputs the full name of the day of the week (e.g., "Monday").
   • the %teth: %te outputs the day of the month, and appending "th" is a formatting choice for ordinal numbers.
   • The + operator concatenates the two parts of the string.

Example Output:

If the system's current date is October 1, 2023, and the above code runs, the output will look something like this:

The current date and time is: Sun Oct 1 00:00:00 IST 2023

My name is Hitesh R. Pulimi.
I was born at 05:30:12 on a Monday,
the 8th 

Key Points:

• The current date and time is fetched by Calendar.getInstance().
• The specific date and time (October 8, 1956) is set using cal.set.
• Formatting specifiers (%tc, %s, %Tr, %tA, %te) are used with printf for nicely formatted output.
