Here we will see what is the __func__ C.Basically the __func__ or __FUNCTION__ (Some old versions of C and C+ + supports __func__). This macro is used to get the name of the current function.Example#include void TestFunction(){ printf("Output of __func__ is: %s", __func__ ); } main() { printf("Output of __func__ is: %s", __func__ ); TestFunction(); }OutputOutput of __func__ is: main Output of __func__ is: TestFunction
The Intel 8086 is 40 pin DIP Microprocessor. Here we will see the actual pin level diagram of 8086 MPU.8086 was the first 16-bit microprocessor available in 40-pin DIP (Dual Inline Package) chip. Let us now discuss in detail the pin configuration of a 8086 Microprocessor.This is the actual pin diagram of 8086 Microprocessor.Now let us see the Pin functions of the 8086 microprocessor.PinsFunctionAD15 – AD0These are 16 address/data bus. AD0-AD7 carries low order byte data and AD8AD15 carries higher order byte data. During the first clock cycle, it carries 16-bit address and after that it carries 16-bit data.A16 – ... Read More
Use the contains() method to search a value in the Quintet class in JavaTuples.Let us first see what we need to work with JavaTuples. To work with Quintet class in JavaTuples, you need to import the following package −import org.javatuples.Quintet;Note − Steps to download and run JavaTuples program. If you are using Eclipse IDE to run Quintet 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.Quintet; public class Demo { public static void main(String[] args) { ...

A JSP directive affects the overall structure of the servlet class. It usually has the following form −There are three types of directive tag −S.No.Directive & Description1Defines page-dependent attributes, such as scripting language, error page, and buffering requirements.2Includes a file during the translation phase.3Declares a tag library, containing custom actions, used in the page
The setBlob() method is used to set value for Blob datatype in the database. It has three variants as follows:void setBlob(int parameterIndex, Blob x): Sets the given Blob value to the parameter at the specified index.void setBlob(int parameterIndex, InputStream inputStream): Sets the contents of the given input stream as a value to the parameter at the specified index.void setBlob(int parameterIndex, InputStream inputStream, long length): Sets the contents of the given input stream as a value to the parameter at the specified index.The setBinaryStream() method is used to set the contents of the given InputStream as a value for the parameter ...

This example demonstrate about How to remove duplications from unsorted linked list in android.Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code to res/layout/activity_main.xml. In the above code, we have taken a text view to show without duplicated values.Step 3 − Add the following code to src/MainActivity.javapackage com.example.myapplication; import android.os.Build; import android.os.Bundle; import android.support.annotation.RequiresApi; import android.support.v7.app.AppCompatActivity; import android.widget.TextView; import java.util.HashSet; import java.util.LinkedList; public class MainActivity extends AppCompatActivity { @RequiresApi(api = ...

If you want to search whether a particular value exist in the Java Octet Tuple, you need to use the contains() method.For example, to find the element “Motherboard”, use it like this −boolean res = oc.contains("Motherboard");As shown above, we have used boolean i.e. the contains() method returns a boolean value; TRUE if the element is in the Tuple, else FALSE.Let us first see what we need to work with JavaTuples. To work with Octet class in JavaTuples, you need to import the following package −import org.javatuples.Octet;Note − Download JavaTuples Jar library to run JavaTuples program. If you are using Eclipse ... Read More
You can use aggregate function SUM() along with IF to determine if a value appears in a GROUP BY group.Let us first create a demo tablemysql> create table GroupbygroupDemo -> ( -> UserId int, -> UserName varchar(20) -> ); Query OK, 0 rows affected (1.48 sec)Insert some records in the table using insert command. The query is as follows −mysql> insert into GroupbygroupDemo values(10, 'John'); Query OK, 1 row affected (0.14 sec) mysql> insert into GroupbygroupDemo values(10, 'Carol'); Query OK, 1 row affected (0.08 sec) mysql> insert into ...

The AbstractList class provides an implementation of the List interface.For an unmodifiable listProgrammer needs to extend this class and provide implementations for the get(int) and size() methods.For a modifiable listProgrammer must override the set(int, E) method. If the list is variable-size the programmer must override the add(int, E) and remove(int) methods.The following is the syntax:public abstract class AbstractList extends AbstractCollection implements ListTo work with the AbstractList class, import the following package:import java.util.AbstractList;The following is an example to implement AbstractList class:Example Live Demoimport java.util.LinkedList; import java.util.AbstractList; public class Demo { public static void main(String[] args) { AbstractList myList ...

You can use $where operator to compare field values in MongoDB. Let us first create a collection with documents> db.comparingFieldDemo.insertOne({"Value1":30, "Value2":40}); { "acknowledged" : true, "insertedId" : ObjectId("5c9c99ed2d6669774125246e") } > db.comparingFieldDemo.insertOne({"Value1":60, "Value2":70}); { "acknowledged" : true, "insertedId" : ObjectId("5c9c99f62d6669774125246f") } > db.comparingFieldDemo.insertOne({"Value1":160, "Value2":190}); { "acknowledged" : true, "insertedId" : ObjectId("5c9c99ff2d66697741252470") } > db.comparingFieldDemo.insertOne({"Value1":200, "Value2":160}); { "acknowledged" : true, "insertedId" : ObjectId("5c9c9a0b2d66697741252471") }Following is the query to display all documents from a collection with the help of find() method> db.comparingFieldDemo.find().pretty();This will produce the following output{ "_id" : ObjectId("5c9c99ed2d6669774125246e"), "Value1" : 30, ...
