An immutable copy of a LocalDate where the required duration is subtracted from it can be obtained using the minus() method in the LocalDate class in Java. This method requires two parameters i.e. the duration to be subtracted and the TemporalUnit of the duration. Also, it returns the LocalDate object with the required duration subtracted from it.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; import java.time.temporal.*; public class Demo { public static void main(String[] args) { LocalDate ld = LocalDate.parse("2019-02-15"); System.out.println("The ...

The toArray() method returns an array containing the elements of this stream.Set the elements in the stream with the IntStream class of() method.IntStream stream = IntStream.of(20, 40, 60, 70, 100, 120, 140);Now, display an array with the elements of this stream using the toArray() method.int[] myArr = stream.toArray();The following is the syntax.int[] toArray()The following is an example to implement IntStream toArray() method in Java.Example Live Demoimport java.util.*; import java.util.stream.IntStream; public class Demo { public static void main(String[] args) { IntStream stream = IntStream.of(20, 40, 60, 70, 100, 120, 140); int[] myArr = stream.toArray(); System.out.println(Arrays.toString(myArr)); } }Output[20, 40, 60, 70, 100, 120, 140]

To generate random values that won’t repeat, use HashSet collection. Firstly, create a random object and HashSet −Random randNum = new Random(); Sets = new HashSet();Now, add random integers −while (s.size() < 10) { s.add(randNum.nextInt()); }Now, display the random numbers that are unique −Listlist = new ArrayList(s); System.out.println(list);Example Live Demoimport java.util.ArrayList; import java.util.HashSet; import java.util.Set; import java.util.Random; import java.util.List; public class Demo { public static void main(String[] args) { Random randNum = new Random(); Sets = new HashSet(); while (s.size() < 10) { s.add(randNum.nextInt()); ...

Here we will see what are the differences between __FUNCTION__, __func__ and the __PRETTY_FUNCTION__ in C++.Basically the __FUNCTION__ and __func__ are same. Some old versions of C and C++ supports __func__. This macro is used to get the name of the current function. The _PRETTY_FUNCTION__ is used to return the detail about the function. Using this we can get which function is used, and in which class it is belonging, etc.Example#include using namespace std; class MyClass{ public: void Class_Function(){ cout
