To get the geographic coordinates of the place that is longitude and latitude of the place we can use google maps geocoding api.RequirementTo get the coordinates of a place, we required geocoding api & you can get it from below link:https://developers.google.com/maps/documentation/geocoding/get-api-keyApart from api_key, we are going to use pythonRequest module (fetch the coordinates)Json module (for conversion).Below is the program to achieve the same:# Import required library import requests import json #Enter the place name place = input("Please enter place name: ") #Place your google map API_KEY to a variable apiKey = 'YOUR_API_KEY' #Store google geocoding api url in a variable ...

The empty() method of the DoubleStream class in Java returns an empty sequential DoubleStream.The syntax is as follows:static DoubleStream empty()To use the DoubleStream class in Java, import the following package:import java.util.stream.DoubleStream;Let us create an empty DoubleStream:DoubleStream doubleStream = DoubleStream.empty();Now, let us check the number of elements in the stream. It will be 0, since the stream is set to empty:doubleStream.count()The following is an example to implement DoubleStream empty() method in Java:Example Live Demoimport java.util.stream.DoubleStream; public class Demo {    public static void main(String[] args) {       DoubleStream doubleStream = DoubleStream.empty();       System.out.println("Number of elements in the stream ...

We almost all use google maps to check distance between source and destination and check the travel time. For developers and enthusiasts, google provide ‘google distance matrix API’ to calculate the distance and duration between two places.To use google distance matrix api, we need google maps API keys, which you can get from below link:https://developers.google.com/maps/documentation/distance-matrix/get-api-keyRequired librariesWe can accomplish this by using different python library, like:PandasgooglemapsRequestsJsonI am using very basic requests and json library. Using pandas you can fill multiple source and destination places at a time and get the result in csv file.Below is the program to implement the same:# ... Read More

The toArray() method returns an array containing the elements of this stream.The syntax is as follows:double[] toArray()To use the DoubleStream class in Java, import the following package:import java.util.stream.DoubleStream;Create DoubleStream and add some elements:DoubleStream doubleStream = DoubleStream.of(20.7, 30.5, 45.9, 60.2, 75.9, 88.3, 95.2);Now, use the toArray() method to return an array with the stream elements:double[] myArr = doubleStream.toArray();The following is an example to implement DoubleStream toArray() method in Java:Example Live Demoimport java.util.*; import java.util.stream.DoubleStream; public class Demo {    public static void main(String[] args) {       DoubleStream doubleStream = DoubleStream.of(20.7, 30.5, 45.9, 60.2, 75.9, 88.3, 95.2);       double[] ...

We generally open the browser to search for a specific site/place on google maps. And if you need to do this task multiple times a day, it becomes very boring. Now you can automate this task where your browser will open automatically and the webpage will show you the google maps of your desired location.InstallationFor this purpose, I’m going to use the paperclip package. As this is not the standard package, we need to install it using pip.>pip install pyperclip Collecting pyperclip Downloading https://files.pythonhosted.org/packages/2d/0f/4eda562dffd085945d57c2d9a5da745cfb5228c02bc90f2c74bbac746243/pyperclip-1.7.0.tar.gz Building wheels for collected packages: pyperclip Building wheel for pyperclip (setup.py) ... done Stored in directory: ...
