C# Enum Equals Method
To find the equality between enums, use the Equals() method.Let’s say we have the following Enum.enum Products { HardDrive, PenDrive, Keyboard};Create two Products objects and assign the same values.Products prod1 = Products.HardDrive; Products prod2 = Products.HardDrive;Now check for equality using Equals() method. It would be True since both have the same underlying value.Exampleusing System; class Program { enum Products {HardDrive, PenDrive, Keyboard}; enum ProductsNew { Mouse, HeadPhone, Speakers}; static void Main() { Products prod1 = Products.HardDrive; Products prod2 = Products.HardDrive; ProductsNew newProd1 = ProductsNew.HeadPhone; ProductsNew ...
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 MoreUse reflection to create, fill, and display an array in Java
An array is created using the java.lang.reflect.Array.newInstance() method. This method basically creates a new array with the required component type as well as length.The array is filled using the java.lang.reflect.Array.setInt() method. This method sets the required integer value at the index specified for the array.The array displayed using the for loop. A program that demonstrates this is given as follows −Exampleimport java.lang.reflect.Array; public class Demo { public static void main (String args[]) { int arr[] = (int[])Array.newInstance(int.class, 10); int size = Array.getLength(arr); for (int i = 0; i
Read MoreC# Enum Format Method
The Format method converts value of a specified enumerated type to its equivalent string representation. Here you can also set the format i.e. d for Decimal, x for HexaDecimal, etc.We have the following enumeration.enum Stock { PenDrive, Keyboard, Speakers };The default value gets assigned (initialize).PenDrive = 0 Keyboard = 1 Speakers = 2Now, let’s say you want the value of “Keyboard” name.Stock st = Stock.Keyboard;For that, try the following and get the constant value for Keyboard name.Enum.Format(typeof(Stock), st, "d")The following is the entire example.Exampleusing System; class Demo { enum Stock { PenDrive, Keyboard, Speakers }; static void Main() ...
Read MoreConvert array to generic list with Java Reflections
An array can be converted into a fixed size list using the java.util.Arrays.asList() method. This method is basically a bridge between array based AP!’s and collection based API’s.A program that demonstrates the conversion of an array into a generic list is given as follows −Exampleimport java.util.Arrays; import java.util.Collections; import java.util.List; public class Demo { public static void main(String[] args) { String str[] = new String[]{"apple", "orange", "mango", "guava", "melon"}; List list = Arrays.asList(str); System.out.println("The list is: " + list); } }The output of the above program is as follows ...
Read MoreC# Program to return specified number of elements from the beginning of a sequence
Set an array and arrange it in descending order using OrderByDescending.int[] prod = { 290, 340, 129, 540, 456, 898, 765, 789, 345};Now, use the Take() method to return specified number of elements from the beginning.Enumerable units = prod.AsQueryable().OrderByDescending(s => s).Take(2);Let us see the complete code.Exampleusing System; using System.Linq; using System.Collections.Generic; public class Demo { public static void Main() { int[] prod = { 290, 340, 129, 540, 456, 898, 765, 789, 345}; // Volume of top two products IEnumerable units = prod.AsQueryable().OrderByDescending(s => s).Take(2); foreach (int res in units) { Console.WriteLine(res); } } }Output898 789
Read MoreSort subset of array elements in Java
The java.util.Arrays.sort() method can be used to sort a subset of the array elements in Java. This method has three arguments i.e. the array to be sorted, the index of the first element of the subset (included in the sorted elements) and the index of the last element of the subset (excluded from the sorted elements). Also, the Arrays.sort() method does not return any value.A program that demonstrates this is given as follows −Exampleimport java.util.Arrays; public class Demo { public static void main(String[] args) { int arr[] = { 1, 9, 7, 3, 2, 8, 4, ...
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) { ...
