C# Console.WindowHeight Property
The WindowHeight property gets or sets the height of the console window.Declare a variable.int height;Now, get the height of the current window.height = Console.WindowHeight;The following is the complete example −Exampleusing System; using System.Numerics; using System.Globalization; class Demo { static void Main() { int height; height = Console.WindowHeight; Console.WriteLine("Current window height = "+height); } }OutputCurrent window height = 0
Read MoreParsing and Formatting a Byte Array into Binary in Java
Set a BigInteger object.BigInteger one;Now, create a ByteArray.byte byteArr[] = new byte[] { 0x1, 0x00, 0x00 }; one = new BigInteger(byteArr);For Binary, we have used 2 as the toString() method parameter.String strResult = one.toString(2);The following is an example −Exampleimport java.math.*; public class Demo { public static void main(String[] args) { // BigInteger object BigInteger one; byte byteArr[] = new byte[] { 0x1, 0x00, 0x00 }; one = new BigInteger(byteArr); String strResult = one.toString(2); System.out.println("ByteArray to Binary = "+strResult); } }OutputByteArray to Binary = 10000000000000000
Read MoreC# difference in milliseconds between two DateTime
Let’s say the following are two DateTime objects for our dates.DateTime date1 = new DateTime(2018, 8, 11, 08, 15, 20); DateTime date2 = new DateTime(2018, 8, 11, 11, 14, 25);Find the difference between both these dates using TimeSpan.TimeSpan ts = date2 - date1;Now to get the Milliseconds, use the following property −ts.TotalMillisecondsLet us see the complete code.Exampleusing System; using System.Linq; public class Demo { public static void Main() { DateTime date1 = new DateTime(2018, 8, 11, 08, 15, 20); DateTime date2 = new DateTime(2018, 8, 11, 11, 14, 25); TimeSpan ts = date2 - date1; Console.WriteLine("No. of Seconds (Difference) = {0}", ts.TotalMilliseconds); } }OutputNo. of Seconds (Difference) = 10745000
Read MoreDictionary Methods in C#
Dictionary is a collection of keys and values in C#. Dictionary is included in the System.Collection.Generics namespace.The following are the methods −Sr.NoMethod & Description1AddAdd key-value pairs in Dictionary2Clear()Remove all keys and values3RemoveRemoves the element with the specified key.4ContainsKeyChecks whether the specified key exists in Dictionary.5ContainsValueChecks whether the specified key value exists in Dictionary.6CountCount the number of key-value pairs.7ClearRemoves all the elements from Dictionary.Let us see how to add elements into a Dictionary and display the count.Exampleusing System; using System.Collections.Generic; public class Demo { public static void Main() { IDictionary d = new Dictionary(); ...
Read MoreDetermine day of week in month from Gregorian Calendar in Java
To work with the GregorianCalendar class, import the following package −import java.util.GregorianCalendar;To get the day of week in month, use the following field −cal.get(Calendar.DAY_OF_WEEK_IN_MONTH)Above, cal is the GregorianCalendar object we created before −GregorianCalendar cal = new GregorianCalendar();The following is an example −Exampleimport java.util.GregorianCalendar; import java.util.Calendar; import java.util.Date; public class Demo { public static void main(String[] args) { GregorianCalendar cal = new GregorianCalendar(); // date information System.out.println("Date Information.........."); System.out.println("Year = " + cal.get(Calendar.YEAR)); System.out.println("Month = " + (cal.get(Calendar.MONTH) + 1)); System.out.println("Date = ...

Read MoreGet byte array from BigInteger in Java
First, set the BigInteger object with binary.BigInteger val = new BigInteger("100000000110001100000", 2);Now, use the toByteArray() method.byte[] byteArr = val.toByteArray();The following is an example −Exampleimport java.math.BigInteger; public class Demo { public static void main(String[] argv) throws Exception { BigInteger val = new BigInteger("100000000110001100000", 2); byte[] byteArr = val.toByteArray(); for (int i = 0; i < byteArr.length; i++) { System.out.format("0x%02X", byteArr[i]); } } }Output0x10 0x0C 0x60
Read MoreHow to initialize an empty DateTime in C#
Set a DateTime to its minimum value.DateTime.MinValue;The above will display the minimum value i.e.1/1/0001Let us see how to display the minimum value and avoid adding null to a date to initialize it as empty.Exampleusing System; using System.Linq; public class Demo { public static void Main() { DateTime dt = DateTime.MinValue; Console.WriteLine(dt); } }Output1/1/0001 12:00:00 AM
Read MoreJava Program to return a Date set to the first possible millisecond of the day after midnight
Let us first set the calendar object.Calendar calendar = Calendar.getInstance();Use the getMinimum() method in Java to return the minimum value for the given calendar field. We will use it to set the minute, hours second and milliseconds.For hour and minute.calendar.set(Calendar.HOUR_OF_DAY, calendar.getMinimum(Calendar.HOUR_OF_DAY)); calendar.set(Calendar.MINUTE, calendar.getMinimum(Calendar.MINUTE));For second and milliseconds.// second calendar.set(Calendar.SECOND, calendar.getMinimum(Calendar.SECOND)); // millisecond calendar.set(Calendar.MILLISECOND, calendar.getMinimum(Calendar.MILLISECOND));The following is an example that returns a Date set to the first possible millisecond of the day after midnight.Exampleimport java.util.Calendar; import java.util.GregorianCalendar; public class Demo { public static void main(String[] argv) throws Exception { Calendar calendar = Calendar.getInstance(); // hour ...
