To list weekday names, use the getWeekdays () from the DateFormatSymbols class in Java.DateFormatSymbols is a class for encapsulating localizable date-time formatting data.Get weekday month names in an array −String[] days = new DateFormatSymbols().getWeekdays ();Display the weekdays −for (int i = 0; i < days.length; i++) {    String weekday = days[i];    System.out.println(weekday); }The following is an example −Example Live Demoimport java.text.DateFormatSymbols; public class Demo {    public static void main(String[] args) {       String[] days = new DateFormatSymbols().getWeekdays();       for (int i = 0; i < days.length; i++) {          String weekday ...

The bits of an integer number can be reversed to obtain another number. An example of this is given as follows −Number = 11 Binary representation = 1011 Reversed binary representation = 1101 Reversed number = 13A program that demonstrates this is given as follows −Example Live Demopublic class Example {    public static void main(String[] args) {       int num = 14;       int n = num;       int rev = 0;       while (num > 0) {          rev = 1;       }       ...

The length of the longest consecutive 1s in the binary representation of a given integer involves converting the integer to its binary form and then identifying the longest run of contiguous 1s. Here, we can represent each integer in binary as a series of 0s and 1s. Bitwise operations allow efficient bit manipulation, making it easy to count and update the longest sequence of consecutive 1s. Consider special cases such as when the integer is 0 (binary representation 0) or when it contains only 1s (e.g., for the number 7, binary 111). To understand the concept clearly, Let's go through ... Read More

Use the ‘d’ date conversion character to display two-digit day of the month, for example, 27, 28, 20, etc.System.out.printf("Two-digit day of the month: %td", d);Above, d is a date object −Date d = new Date();The following is an example −Example Live Demoimport java.util.Date; import java.text.DateFormat; import java.text.SimpleDateFormat; public class Demo {    public static void main(String[] args) throws Exception {       Date d = new Date();       DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss a");       String format = dateFormat.format(d);       System.out.println("Current date and time = " + format);       System.out.printf("Four-digit Year ...

In this article, we will discuss how to display the two-digit month. A two-digit month ensures that even the first month (i.e., January) is formatted to display as 01 instead of 1. This formatting provides a consistent two-digit representation for all months. To Display two-digit month in Java is quite easy. Let us learn the following ways: Displaying Two-Digit Month Using the "%tm" Specifier To retrieve a two-digit month from a given date, we can use the "%tm" specifier. This format specifier is used with the printf() method to display the month of a date as a two-digit number. Example ... Read More

Use the ‘j’ date conversion character to display three-digit day of the year.System.out.printf("Three-digit Day of the Year: %tj/%Tj", d, d);Above, d is a date object −Date d = new Date();The following is an example −Example Live Demoimport java.util.Date; import java.text.DateFormat; import java.text.SimpleDateFormat; public class Demo {    public static void main(String[] args) throws Exception {       Date d = new Date();       DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss a");       String format = dateFormat.format(d);       System.out.println("Current date and time = " + format);       System.out.printf("Four-digit Year = %TY", d);     ...

Use the ‘Y’ date conversion character to display four-digit year.System.out.printf("Four-digit Year = %TY",d);Above, d is a date object −Date d = new Date();The following is an example −Example Live Demoimport java.util.Date; import java.text.DateFormat; import java.text.SimpleDateFormat; public class Demo {    public static void main(String[] args) throws Exception {       Date d = new Date();       DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss a");       String format = dateFormat.format(d);       System.out.println("Current date and time = " + format);       System.out.printf("Four-digit Year = %TY",d);    } }OutputCurrent date and time = 26/11/2018 11:56:26 AM Four-digit Year = 2018

Use the ‘C’ date conversion character to display two digits of year −System.out.printf("Two-digit Year (Century Name) = %tC/%TC", d, d);Above, d is a date object −Date d = new Date();The following is an example −Example Live Demoimport java.util.Date; import java.text.DateFormat; import java.text.SimpleDateFormat; public class Demo {    public static void main(String[] args) throws Exception {       Date d = new Date();       DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss a");       String format = dateFormat.format(d);       System.out.println("Current date and time = " + format);       System.out.printf("Localized day name = %tA/%TA", d, d); ...

In this article, we will talk about creating iterators for efficient looping in Python functions. An iterator is something that helps you go through all the items one by one, like going through pages of a book one page at a time. In Python, we can use lists, tuples, dictionaries, and sets as iterators. So we will explore Python functions that generate iterators for efficient looping. Creating Iterators with Functions Python provides different ways to create iterators using functions. So let us see some examples of creating iterators for efficient looping in Python functions - Using Generator Functions Using ... Read More
