There are different scoping rules for lambda expression in Java. In lambda expressions, this and super keywords are lexically scoped means that this keyword refers to the object of the enclosing type and the super keyword refers to the enclosing superclass. In the case of an anonymous class, they are relative to the anonymous class itself. Similarly, local variables declared in lambda expression conflicts with variables declared in the enclosing class. In the case of an anonymous class, they are allowed to shadow variables in the enclosing class.Example@FunctionalInterface interface TestInterface {    int calculate(int x, int y); } class Test {    public ...

To get the number of elements actually contained in the ArrayList, the code is as follows −Example Live Demousing System; using System.Collections; public class Demo {    public static void Main(String[] args){       ArrayList list1 = new ArrayList();       list1.Add("A");       list1.Add("B");       list1.Add("C");       list1.Add("D");       list1.Add("E");       list1.Add("F");       list1.Add("G");       list1.Add("H");       list1.Add("I");       Console.WriteLine("Elements in ArrayList1...");       foreach (string res in list1){          Console.WriteLine(res);       }     ...

To get the minimum value in the SortedSet, the code is as follows −Example Live Demousing System; using System.Collections.Generic; public class Demo {    public static void Main(){       SortedSet set1 = new SortedSet();       set1.Add("AB");       set1.Add("BC");       set1.Add("CD");       set1.Add("EF");       Console.WriteLine("Elements in SortedSet1...");       foreach (string res in set1){          Console.WriteLine(res);       }       Console.WriteLine("Maximum element in SortedSet1 = " + set1.Max);       Console.WriteLine("Minimum element in SortedSet1 = " + set1.Min);       SortedSet ...
