Read MoreConvert LinkedList to ArrayList in Java
A LinkedList can be converted into an ArrayList by creating an ArrayList such that the parameterized constructor of the ArrayList initialises it with the elements of the LinkedList.A program that demonstrates this is given as follows −Exampleimport java.util.ArrayList; import java.util.LinkedList; import java.util.List; public class Demo { public static void main(String[] args) { LinkedList l = new LinkedList(); l.add("Orange"); l.add("Apple"); l.add("Peach"); l.add("Guava"); l.add("Pear"); List aList = new ArrayList(l); System.out.println("The ArrayList elements are: "); for ...
Read MoreConvert.ToSByte Method in C#
Convert a specified value to an 8-bit signed integer i.e. SByte.It is a signed 8-bit integer data type which stores value between -128 to 127.Let us see an example. We have a double variable.double doubleNum = -19.9;Now, let us convert it to SByte.sbyte res; res = Convert.ToSByte(doubleNum);Exampleusing System; public class Demo { public static void Main() { double doubleNum = -19.9; sbyte res; res = Convert.ToSByte(doubleNum); Console.WriteLine("Converted {0} to {1}", doubleNum, res); } }OutputConverted -19.9 to -20
Read MoreC++ Program to Find Quotient and Remainder
Quotient and Remainder are parts of division along with dividend and divisor.The number which we divide is known as the dividend. The number which divides the dividend is known as the divisor. The result obtained after the division is known as the quotient and the number left over is the remainder.dividend = divisor * quotient + remainderFor Example: If 15 is divided by 7, then 2 is the quotient and 1 is the remainder. Here, 15 is the dividend and 7 is the divisor.15 = 7 * 2 + 1A program to find quotient and remainder is as follows:Example#include ...
Read MoreJava Program to convert String to byte array
Here is our string.String str = "Asia is a continent!";Now let us use a byte array and the getBytes() method to fulfill our purpose.byte[] byteVal = str.getBytes();Now, if we will get the length of the array, it would return the length as shown in the complete example below −Examplepublic class Demo { public static void main(String args[]) { String str = "Asia is a continent!"; System.out.println(str); // converted to byte array byte[] byteVal = str.getBytes(); // getting the length System.out.println(byteVal.length); } }OutputAsia is a continent! 20
Read MoreDecimalFormat("###E0") in Java
DecimalFormat is a concrete subclass of NumberFormat that formats decimal numbers. Let us set DecimalFormat("###E0") and use the format() method as well.DecimalFormat decFormat = new DecimalFormat("##E0"); System.out.println(decFormat.format(-267.9965)); System.out.println(decFormat.format(8.19)); System.out.println(decFormat.format(9897.88));Since we have used DecimalFormat class in Java, therefore importing the following package is a must −import java.text.DecimalFormat;The following is the complete example −Exampleimport java.text.DecimalFormat; public class Demo { public static void main(String[] argv) throws Exception { DecimalFormat decFormat = new DecimalFormat("###E0"); System.out.println(decFormat.format(-267.9965)); System.out.println(decFormat.format(8.19)); System.out.println(decFormat.format(9897.88)); ...
Read MoreSimpleDateFormat('E, dd MMM yyyy HH:mm:ss Z') in Java
Using the SimpleDateFormat(“E, dd MMM yyyy HH:mm:ss Z”), wherein E is for Day of Week −// displaying current date and time Calendar cal = Calendar.getInstance(); SimpleDateFormat simpleformat = new SimpleDateFormat("E, dd MMM yyyy HH:mm:ss Z"); System.out.println("Today's date and time = "+simpleformat.format(cal.getTime()));Since we have used the Format and SimpleDateFormat class above, therefore import the following packages. With that, we have also used the Date −import java.text.Format; import java.text.SimpleDateFormat; import java.util.Date;The following is an example −Exampleimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { ...
Read MoreConvert.ToInt64 Method in C#
Convert a specified value to a 64-bit signed integer using Convert.ToInt64 Method.Let us take a double value.double doubleNum = 193.834;Now, convert it to Int64 i.e. long.long res; res = Convert.ToInt32(doubleNum);Exampleusing System; public class Demo { public static void Main() { double doubleNum = 193.834; long res; res = Convert.ToInt32(doubleNum); Console.WriteLine("Converted {0} to {1}", doubleNum, res); } }OutputConverted 193.834 to 194
Read MoreHow to create a thread in C#?
Threads are lightweight processes. A thread is defined as the execution path of a program. Threads are created by extending the Thread class. The extended Thread class then calls the Start() method to begin the child thread execution.Example of Thread: One common example of use of thread is implementation of concurrent programming by modern operating systems. Use of threads saves wastage of CPU cycle and increase efficiency of an application.The following is an example showing how to create a thread.Exampleusing System; using System.Threading; namespace Demo { class Program { public static void ThreadFunc() { ...
Read MoreC++ Program to find size of int, float, double and char in Your System
Data Types in C++There are many data types in C++ but the most frequently used are int, float, double and char. Some details about these data types are as follows −int - This is used for integer data types which normally require 4 bytes of memory space.float - This is used for storing single precision floating point values or decimal values. float variables normally require 4 bytes of memory space.double - This is used for storing double precision floating point values or decimal values. Double variables normally require 8 bytes of memory space.char - This is used for storing characters. ...
