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]
The following is the syntax to merge two tables using MySQL unioncreate table yourTableName ( select *from yourTableName1 ) UNION ( select *from yourTableName2 );To understand the above syntax, let us create a table. The query to create first table is as followsmysql> create table Old_TableDemo -> ( -> UserId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> UserName varchar(20) -> ); Query OK, 0 rows affected (0.63 sec)The query to create second table is as followsmysql> create table Old_TableDemo2 ...

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
To define Temporary Register, we can mention that it is an 8-bit non-programmable resister used to hold data during an arithmetic and logic operation (temporary resister is used to hold intermediate result). The result is stored in the accumulator, and the flags (flip-flops) are set or reset according to the result of the operation.W and Z are two 8-bit temporary registers of 8085 microprocessor, which is not accessible to the user. They are exclusively used for the internal operation by the microprocessor. These registers are used either to store 8-bit of information in each W and Z registers or a ... Read More

The addAtX() method is used to add a value to the Quartet Tuple. The index can be set here with the X i.e. the place where the value gets added.Let us first see what we need to work with JavaTuples. To work with Quartet class in JavaTuples, you need to import the following package −import org.javatuples.Quartet;We will use Quintet class; therefore, we will import the following package −import org.javatuples.Quintet;Note − Steps to download and run JavaTuples program If you are using Eclipse IDE to run Quartet Class in JavaTuples, then Right Click Project → Properties → Java Build Path → ...
