The asLongStream() method of the IntStream class returns a LongStream consisting of the elements of this stream, converted to long.The syntax is as followsLongStream asLongStream()Create an IntStream and add some elements in the StreamIntStream intStream = IntStream.of(30, 40, 60, 70, 90, 110, 140, 150);Now, use the asLongStream() method to convert it to longLongStream longStream = intStream.asLongStream();The following is an example to implement IntStream asLongStream() method in JavaExample Live Demoimport java.util.*; import java.util.stream.IntStream; import java.util.stream.LongStream; public class Demo { public static void main(String[] args) { IntStream intStream = IntStream.of(30, 40, 60, 70, 90, ...

The day of the week for a particular LocalDate can be obtained using the getDayOfWeek() method in the LocalDate class in Java. This method requires no parameters and it returns the day of the week.A program that demonstrates this is given as followsExample Live Demoimport java.time.*; public class Demo { public static void main(String[] args) { LocalDate ld = LocalDate.parse("2019-02-14"); System.out.println("The LocalDate is: " + ld); System.out.println("The day of the week is: " + ld.getDayOfWeek()); } }OutputThe LocalDate is: 2019-02-14 The day of the week is: THURSDAYNow let us understand ...

Yes, deleting row from view delete row from base table. Let us understand this by creating a new table. The query to create a table is as followsmysql> create table deleteFromBaseTableDemo -> ( -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> Name varchar(20) -> ); Query OK, 0 rows affected (0.83 sec)Insert some records in the table using insert command. The query is as follows −mysql> insert into deleteFromBaseTableDemo(Name) values('John'); Query OK, 1 row affected (0.18 sec) mysql> insert into deleteFromBaseTableDemo(Name) values('Carol'); Query OK, 1 row affected ...

The clear() method of the AbstractCollection class is used to remove all the elements from this collection. This makes the collection empty.The syntax is as follows:public void clear()To work with AbstractCollection class in Java, import the following package:import java.util.AbstractCollection;First, create AbstractCollection and add some elements using the add() method:AbstractCollection absCollection = new ArrayList(); absCollection.add("These"); absCollection.add("are"); absCollection.add("demo"); absCollection.add("elements");Now, clear the AbstractCollection:absCollection.clear();The following is an example to implement AbstractCollection clear() method in Java:Example Live Demoimport java.util.ArrayList; import java.util.AbstractCollection; public class Demo { public static void main(String[] args) { AbstractCollection absCollection = new ArrayList(); absCollection.add("These"); ...

In order to insert Date() in MongoDB through Mongo shell, use the following syntaxvar yourVariableName= new Date(year, month, day, hour, minute); db.yourCollectionName({yourDateFieldName:yourVariableName});Let us first create a date variable> var creatingDate = new Date(2019, 03, 29, 13, 12);Let us create a collection with documents:>db.insertingDateUsingVariableDemo.insertOne({"UserName":"John", "UserMessages":["Hi", "Hello", "Awesome"], "UserPostDate":creatingDate});Following is the query to display all documents from a collection with the help of find() method> db.insertingDateUsingVariableDemo.find().pretty();This will produce the following output{ "_id" : ObjectId("5c9d1b19a629b87623db1b21"), "UserName" : "John", "UserMessages" : [ "Hi", "Hello", "Awesome" ], "UserPostDate" : ISODate("2019-04-29T07:42:00Z") }Read More
You can use subquery for this. Let us first create a table −mysql> create table DemoTable ( Id int ); Query OK, 0 rows affected (0.68 sec)Insert some records in the table using insert command −mysql> insert into DemoTable values(100); Query OK, 1 row affected (0.16 sec) mysql> insert into DemoTable values(115); Query OK, 1 row affected (0.32 sec) mysql> insert into DemoTable values(200); Query OK, 1 row affected (0.28 sec) mysql> insert into DemoTable values(140); Query OK, 1 row affected (0.16 sec) mysql> insert into DemoTable values(124); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable ...

Now let us see a program of Intel 8085 Microprocessor. In this program we will see how to convert 16-bit binary data to BCD data.Problem Statement:Write 8085 Assembly language program to convert 16-bit binary data to BCD data. The binary data is stored at location 8000H and 8001H.Discussion:This problem is solved by implementing 16-bit counter. We are storing the 16-bit number at first, then decreasing the numbers one by one, and increasing the decimal value by adjusting the decimal value. To increase the value, we can use the INR instruction, but INR instruction does not affect the carry flag. So ... Read More
In this section we will see how to reset the accumulator content in Intel 8085 and 8086 microprocessors.In both of the microprocessors, there are four instructions to do the work. These instructions are doing the same in both cases.Let us see the 8085 instructions first to reset the Accumulator.MnemonicsDescriptionMVI A, 00HThis instruction loads 00H into the accumulator. This is two-byte instruction.ANI 00HThis instruction performs AND operation between accumulator and 00H. This is also a two-byte instruction.XRA AThis one-byte instruction is performing the XOR operation with accumulator itself.SUB ASUB A is another one-byte instruction. It subtracts accumulator value from the accumulator. The ... Read More
Let us first see what we need to work with JavaTuples. To work with Septet class in JavaTuples, you need to import the following package −import org.javatuples.Septet;Note − Steps to download and run JavaTuples program. If you are using Eclipse IDE to run Septet Class in JavaTuples, then Right Click Project → Properties → Java Build Path → Add External Jars and upload the downloaded JavaTuples jar file.The following is an example −Exampleimport org.javatuples.Septet; public class Demo { public static void main(String[] args) { String[] myArr = { ...

The plugin action is used to insert Java components into a JSP page. It determines the type of browser and inserts the or tags as needed.If the needed plugin is not present, it downloads the plugin and then executes the Java component. The Java component can be either an Applet or a JavaBean.The plugin action has several attributes that correspond to common HTML tags used to format Java components. The element can also be used to send parameters to the Applet or Bean.Following is the typical syntax of using the plugin action − ... Read More
