Let’s say the following is our String List −List list = Arrays.asList("Football", "Basketball", "Hockey", "Cricket", "Fencing");Now, map to add string to each element −List str = list.stream().map(name -> "Sports " + name + " Outdoor") .collect(Collectors.toList());Above, we have added “Sports” and “Outdoor” strings to each element.The following is an example to Map and add string value to each element in Java −Exampleimport java.util.Arrays; import java.util.List; import java.util.stream.Collectors; public class Demo { public static void main(String[] args) { List list = Arrays.asList("Football", "Basketball", "Hockey", "Cricket", "Fencing"); List str = list.stream().map(name -> "Sports " ...

To begin with, Polymorphism is gotten from the Greek words Poly (which means many) and morphism (which meaning forms).Polymorphism portrays an example in object-oriented programming where methods in various classes that do similar things should have a similar name. Polymorphism is essentially an OOP pattern that enables numerous classes with different functionalities to execute or share a commonInterface. The usefulness of polymorphism is code written in different classes doesn't have any effect which class it belongs because they are used in the same way. In order to ensure that the classes do implement the polymorphism guideline, we can pick between ... Read More

In C we can pass parameters in two different ways. These are call by value, and call by address, In C++, we can get another technique. This is called Call by reference. Let us see the effect of these, and how they work.First we will see call by value. In this technique, the parameters are copied to the function arguments. So if some modifications are done, that will update the copied value, not the actual value.Example#include using namespace std; void my_swap(int x, int y) { int temp; temp = x; x = y; y = ...

The toString() method of the java.sql.Timestamp class returns the JDBC escape format of the time stamp of the current Timestamp object as String variable.i.e. using this method you can convert a Timestamp object to a String.//Retrieving the Time object Timestamp timestampObj = rs.getTimestamp("DispatchTimeStamp"); //Converting the Time object to String format String time_stamp = timestampObj.toString();ExampleLet us create a table with the name dispatches_data in MySQL database using CREATE statement as shown below:CREATE TABLE dispatches_data( ProductName VARCHAR(255), CustomerName VARCHAR(255), DispatchTimeStamp timestamp, Price INT, Location VARCHAR(255));Now, we will insert 5 records in dispatches_data table using INSERT statements:insert into ...
