The lambda expressions are introduced in Java 8. It is one of the most popular features of Java 8 and brings functional programming capabilities to Java. By using a lambda expression, we can directly write the implementation for a method in Java.In the below program, we can create a thread by implementing the Runnable interface using lamda expression. While using the lambda expressions, we can skip the new Runnable() and run() method because the compiler knows that Thread object takes a Runnable object and that contains only one method run() that takes no argument.Examplepublic class LambdaThreadTest {    public static void main(String args[]) {     ...

To get the capacity of a SortedList, the code is as follows −Example Live Demousing System; using System.Collections; public class Demo {    public static void Main(String[] args){       SortedList sortedList = new SortedList();       sortedList.Add("A", "1");       sortedList.Add("B", "2");       sortedList.Add("C", "3");       sortedList.Add("D", "4");       sortedList.Add("E", "5");       sortedList.Add("F", "6");       sortedList.Add("G", "7");       sortedList.Add("H", "8");       sortedList.Add("I", "9");       sortedList.Add("J", "10");       Console.WriteLine("SortedList elements...");       foreach(DictionaryEntry d in sortedList){       ...

To check whether the Unicode character is a separator character, the code is as follows −Example Live Demousing System; public class Demo {    public static void Main(){       bool res;       char val = ', ';       Console.WriteLine("Value = "+val);       res = Char.IsSeparator(val);       Console.WriteLine("Is the value a separator? = "+res);    } }OutputThis will produce the following output −Value = , Is the value a separator? = FalseExampleLet us now see another example − Live Demousing System; public class Demo {    public static void Main(){       ...

To convert the value of the specified Decimal to the equivalent 8-bit unsigned integer, the code is as follows −Example Live Demousing System; public class Demo {    public static void Main(){       Decimal val1 = 6.59m;       Decimal val2 = 30.12m;       Decimal val3 = 69.34m;       Console.WriteLine("Decimal 1 = "+val1);       Console.WriteLine("Decimal 2 = "+val2);       Console.WriteLine("Decimal 3 = "+val3);       byte res1 = Decimal.ToByte(val1);       byte res2 = Decimal.ToByte(val2);       byte res3 = Decimal.ToByte(val3);       Console.WriteLine("Byte value1 (Decimal ...

To get the TypeCode for value type Decimal, the code is as follows −Example Live Demousing System; public class Demo {    public static void Main(){       Decimal val = Decimal.MaxValue;       Console.WriteLine("Decimal Value = {0}", val);       Console.WriteLine("HashCode = {0}", (val.GetHashCode()) );       TypeCode type = val.GetTypeCode();       Console.WriteLine("TypeCode = "+type);    } }OutputThis will produce the following output −Decimal Value = 79228162514264337593543950335 HashCode = 1173356544 TypeCode = DecimalExampleLet us now see another example − Live Demousing System; public class Demo {    public static void Main(){     ...

To get the hash code for the current Decimal instance, the code is as follows −Example Live Demousing System; public class Demo {    public static void Main(){       Decimal val = 135269.38193M;       Console.WriteLine("Decimal Value = {0}", val);       Console.WriteLine("HashCode = {0}", (val.GetHashCode()) );    } }OutputThis will produce the following output −Decimal Value = 135269.38193 HashCode = 1328665595ExampleLet us now see another example − Live Demousing System; public class Demo {    public static void Main(){       Decimal val = Decimal.MaxValue;       Console.WriteLine("Decimal Value = {0}", val);       Console.WriteLine("HashCode = {0}", (val.GetHashCode()) );    } }OutputThis will produce the following output −Decimal Value = 79228162514264337593543950335 HashCode = 1173356544

To convert the specified string representation of a logical value to its Boolean equivalent, the code is as follows −Example Live Demousing System; public class Demo {    public static void Main(){       bool val;       bool flag;       val = Boolean.TryParse("true", out flag);       Console.WriteLine("Result = "+val);    } }OutputThis will produce the following output −Example Live Demousing System; public class Demo {    public static void Main() {       bool val; bool flag;       val = Boolean.TryParse("$", out flag);       Console.WriteLine("Result = "+val);    } }OutputThis will produce the following output −Result = False

To convert the value of the current DateTime object to Coordinated Universal Time (UTC), the code is as follows −Example Live Demousing System; public class Demo {    public static void Main() {       DateTime d = new DateTime(2019, 12, 11, 7, 11, 25);       Console.WriteLine("Date = {0}", d);       DateTime res = d.ToUniversalTime();       Console.WriteLine("String representation = {0}", res);    } }OutputThis will produce the following output −Date = 11/11/2019 7:11:25 AM String representation = 11/11/2019 7:11:25 AMExampleLet us now see another example − Live Demousing System; public class Demo {    public ...

To get the capacity of a list, the code is as follows −Example Live Demousing System; using System.Collections.Generic; public class Demo {    public static void Main(String[] args){       List list1 = new List();       list1.Add("One");       list1.Add("Two");       list1.Add("Three");       list1.Add("Four");       list1.Add("Five");       Console.WriteLine("Elements in List1...");       foreach (string res in list1){          Console.WriteLine(res);       }       Console.WriteLine("Capacity of List1 = "+list1.Capacity);       List list2 = new List();       list2.Add("India");     ...
