Change date formatting symbols in Java
For date formatting symbols, use the DateFormatSymbols class.Firstly, set weekdays using a string arrayString[] weekDays2 = { "", "monday", "tuesday", "wednesday", "thursday", "friday", "saturday", "sunday" };Now, set short week days withDateFormatSymbols mySymbols = new DateFormatSymbols(); mySymbols.setShortWeekdays(weekDays2);Get the date −dateFormat = new SimpleDateFormat("EEEE, dd MMM yyyy", mySymbols); System.out.println(dateFormat.format(new Date()));The following is an example −Exampleimport java.text.SimpleDateFormat; import java.text.DateFormat; import java.text.DateFormatSymbols; import java.util.Date; public class Demo { public static void main(String[] args) { String[] weekDays1 = { "", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday" }; String[] weekDays2 = { "", "monday", "tuesday", "wednesday", "thursday", "friday", ...
Read MoreJava program to print all distinct elements of a given integer array in Java
All distinct elements of an array are printed i.e. all the elements in the array are printed only once and duplicate elements are not printed. An example of this is given as follows.Array = 1 5 9 1 4 9 6 5 9 7 Distinct elements of above array = 1 5 9 4 6 7A program that demonstrates this is given as follows.Examplepublic class Example { public static void main (String[] args) { int arr[] = {1, 5, 9, 1, 4, 9, 6, 5, 9, 7}; int n = arr.length; ...
Read MoreConvert.ToUInt32 Method in C#
Convert a specified value to a 32-bit unsigned integer using the Convert.ToUInt32 method.The following is our string.string str = "210";Now, let us convert it to a 32-bit unsigned integer.uint res; res = Convert.ToUInt32(str);Exampleusing System; public class Demo { public static void Main() { string str = "210"; uint res; res = Convert.ToUInt32(str); Console.WriteLine("Converted string '{0}' to {1}", str, res); } }OutputConverted string '210' to 210
Read MoreJava Program to list Short Weekday Names
To list short weekday names, use the getShortWeekdays() from the DateFormatSymbols class in Java.DateFormatSymbols is a class for encapsulating localizable date-time formatting data.Get short weekday names in an arrayString[] days = new DateFormatSymbols().getShortWeekdays();Display the weekdayfor (int i = 0; i < days.length; i++) { String weekday = days[i]; System.out.println(weekday); }The following is an example −Exampleimport java.text.DateFormatSymbols; public class Demo { public static void main(String[] args) { String[] days = new DateFormatSymbols().getShortWeekdays(); for (int i = 0; i < days.length; i++) { String weekday = days[i]; System.out.println(weekday); } } }OutputSun Mon Tue Wed Thu Fri Sat
Read MoreUnderstanding IndexOutOfRangeException Exception in C#
It occurs when Index is outside the bounds of the array.Let us see an example. We have declare an array with 5 elements and set the size as 5.int[] arr = new int[5]; arr[0] = 10; arr[1] = 20; arr[2] = 30; arr[3] = 40; arr[4] = 50;Now, we try to add the value of an element that extends the size of our array i.e.arr[5] = 60;Above, we are trying to add element at 6th position.Exampleusing System; using System.IO; using System.Collections.Generic; namespace Demo { class Program { static void Main(string[] args) { ...
Read MoreJava Program to decrement a Date using the Calendar Class
Import the following package for Calendar class in Javaimport java.util.Calendar;Firstly, create a Calendar object and display the current dateCalendar calendar = Calendar.getInstance(); System.out.println("Current Date = " + calendar.getTime());Now, let us decrement the date using the add() method and Calendar.DATE constant. Set a negative value since we are decrementing the datecalendar.add(Calendar.DATE, -3);The following is an exampleExampleimport java.util.Calendar; public class Demo { public static void main(String[] args) { Calendar calendar = Calendar.getInstance(); System.out.println("Current Date = " + calendar.getTime()); // Decrementing date by 3 calendar.add(Calendar.DATE, -3); System.out.println("Updated ...
Read MoreReverse words in a given String in Java
The order of the words in a string can be reversed and the string displayed with the words in reverse order. An example of this is given as follows.String = I love mangoes Reversed string = mangoes love IA program that demonstrates this is given as follows.Exampleimport java.util.regex.Pattern; public class Example { public static void main(String[] args) { String str = "the sky is blue"; Pattern p = Pattern.compile("\s"); System.out.println("The original string is: " + str); String[] temp = p.split(str); String rev = ""; ...
Read MoreWhy are global and static variables initialized to their default values in C/C++?
Global and static variables are initialized to their default values because it is in the C or C++ standards and it is free to assign a value by zero at compile time. Both static and global variable behave same to the generated object code. These variables are allocated in .bss file and at the time of loading it allocates the memory by getting the constants alloted to the variables.The following is an example of global and static variables.Example#include int a; static int b; int main() { int x; static int y; int z = 28; ...
Read MoreDecrement a Month using the Calendar Class in Java
Import the following package for Calendar class in Javaimport java.util.Calendar;Firstly, create a Calendar object and display the current dateCalendar calendar = Calendar.getInstance(); System.out.println("Current Date = " + calendar.getTime());Now, let us decrement the month using the add() method and Calendar.MONTH constant. Set a negative value here since we are decrementingcalendar.add(Calendar.MONTH, -2);The following is an exampleExampleimport java.util.Calendar; public class Demo { public static void main(String[] args) { Calendar calendar = Calendar.getInstance(); System.out.println("Current Date = " + calendar.getTime()); // Decrementing Month by 2 calendar.add(Calendar.MONTH, -2); System.out.println("Updated Date ...

The byteLength property of the SharedArrayBuffer returns an unsigned, 32-bit integer that specifies the size/length of a SharedArrayBuffer. Syntax Its Syntax is as follows sharedArrayBuffer.byteLength Example JavaScript Example var sharedArrayBuffer = new SharedArrayBuffer(8); var result = sharedArrayBuffer.byteLength; document.write("length of the shared array buffer is: " + result); Output length of the shared array buffer is: 8
