Here we will see how to print 1 to 1000 without loop or any conditional statements. As the loops cannot be used, so we can try recursions, but here another constraint that, we cannot use the conditions also. So the base case of the recursion will not be used.Here we are solving this problem using static members. At first we are initializing the static member with 1, then in the constructor we are printing the value and increase its value. Now create an array of 1000 objects of that class, so 1000 different objects are created, so the constructor is ... Read More
To correctly use aggregate function with where clause in MySQL, the following is the syntax −select *from yourTableName where yourColumnName > (select AVG(yourColumnName) from yourTableName);To understand the above concept, let us create a table. The query to create a table is as follows −mysql> create table EmployeeInformation -> ( -> EmployeeId int, -> EmployeeName varchar(20), -> EmployeeSalary int, -> EmployeeDateOfBirth datetime -> ); Query OK, 0 rows affected (1.08 sec)Now you can insert some records in the table using insert command. The query is as follows −mysql> insert into EmployeeInformation values(101, 'John', 5510, '1995-01-21'); ... Read More
This example demonstrate about How to get the duplicates values from Arraylist and then get those items in another Arraylist.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 listview to show duplication list items from array list.Step 3 − Add the following code to src/MainActivity.javapackage com.example.andy.myapplication; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.widget.ArrayAdapter; import android.widget.ListView; import java.util.ArrayList; import java.util.HashSet; import java.util.Set; public class MainActivity extends AppCompatActivity ...

Here we will see what are the __FILE, __LINE__ and __FUNCTION__ in C++.The __FILE__This macro is used to get the path of the current file. This is useful when we want to generate log files. The following code will explain its functionality.Example#include using namespace std; int errorLog (const char* file, const std::string& msg){ cerr
Reading from the StackLet us consider that SP contents the address FC78H, and we want to read information from a stack location. In this case, we are not interested in reading from a location whose address is less than the memory address present in SP. This is because 8085 interprets them as useless information. For example, there is no point in reading useless information from memory location FC75H.SP interprets that, memory locations FC78H, FC79H, ..., FFFFH are all interpreted by 8085 to have useful information. To read from Stack, the instruction is POP in 8085 microprocessor instruction set. Here we ... Read More

The tag is a commonly used tag because it iterates over a collection of objects. The tag is used to break a string into tokens and iterate through each of the tokens.AttributeThe tag has the following attributes −AttributeDescriptionRequiredDefaultitemsInformation to loop overNoNonebeginElement to start with (0 = first item, 1 = second item, ...)No0endElement to end with (0 = first item, 1 = second item, ...)NoLast elementstepProcess every step itemsNo1varName of the variable to expose the current itemNoNonevarStatusName of the variable to expose the loop statusNoNoneExample for Tag Example Item The above code will generate the following result −Item 1 Item 2 Item 3 Item 4 Item 5
