Jobs in drone technology-driven enterprises are the jobs of the future because drones are going to play a very crucial role across a large number of industries in future. Many youngsters think that jobs in the drone domain involve just engineering and technological openings but the fact is there are many other openings which don't require you to be a technological wizard.Drone PilotingThis is one specialization that is already opening up many opportunities for youngsters. Drones are finding application in different sectors like mining, security services including private security for industrial and commercial assets, disaster management, logistics and many others. ...

Our task is to create a child process and display process id of both parent and child process using fork() function in Python.When we use fork(), it creates a copy of itself, it is a very important aspect of LINUX, UNIX. fork() is mainly applicable for multithreading environment that means the execution of the thread is duplicated created a child thread from a parent thread. When there is an error, the method will return a negative value and for the child process, it returns 0, Otherwise, it returns positive value that means we are in the parent process.The fork() module ...

In this section we will see how two sorted lists can be merged using the heapq module in Python. As an example, if list1 = [10, 20, 30, 40] and list2 = [100, 200, 300, 400, 500], then after merging it will return list3 = [10, 20, 30, 40, 100, 200, 300, 400, 500]To perform this task, we will use the heapq module. This module comes with Python as Standard Library Module. So we need to import it before using it.import heapqThe heapq module has some properties. These are like below −Method heapq.heapify(iterable)It is used to convert an iterable dataset ... Read More
This example demonstrate about How to get locale information from Network provider 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 text view to show locale infomation.Step 3 − Add the following code to src/MainActivity.javapackage com.example.myapplication; import android.Manifest; import android.content.pm.PackageManager; import android.location.Address; import android.location.Geocoder; import android.location.Location; import android.location.LocationManager; import android.os.Build; import android.os.Bundle; import android.support.annotation.RequiresApi; import android.support.v4.app.ActivityCompat; import android.support.v7.app.AppCompatActivity; import android.widget.TextView; import java.io.IOException; ...

In the world of business, Unicorns are by no means the mythical single horned Equus; it refers to the category of companies called startups with a valuation of over a billion dollars. Hence, recycling unicorns are nothing but startups in the recycling sector that are worth over a billion dollars. It was venture capitalist Aileen Lee who first coined the term 'unicorn' for startups that broke the billion-dollar threshold and the reason he did so was that startups that are worth a billion dollars are as elusive as the mythical unicorn. And yet, there are over 200 unicorns around the ... Read More
To validate if a String has only numbers, you can try the following codes. We have used the matches() method in Java here to check for number in a string.Example Live Demopublic class Demo { public static void main(String []args) { String str = "978"; System.out.println("Checking for string that has only numbers..."); System.out.println("String: "+str); if(str.matches("[0-9]+") && str.length() > 2) System.out.println("String has only numbers!"); else System.out.println("String consist of characters as well!"); } }OutputChecking for string that has only numbers... ...

To check whether the entered value is a letter or not in Java, use the Character.isLetter() method.We have a value to be checked.char val = 'D';Now let us use the Character.isLetter() method.if (Character.isLetter(val)) { System.out.println("Character is in Lowercase!"); }else { System.out.println("Character is in Uppercase!"); }Let us see the complete example now to check for letter.Example Live Demopublic class Demo { public static void main(String []args) { System.out.println("Checking whether the given value is a Letter or not..."); char val = 'D'; System.out.println("Value: "+val); if (Character.isLetter(val)) { ...

Python is a scripting language while C is a programming language. C/C++ is relatively fast as compared to Python because when you run the Python script, its interpreter will interpret the script line by line and generate output but in C, the compiler will first compile it and generate an output which is optimized with respect to the hardware. In case of other languages such as Java and.NET, Java bytecode, and .NET bytecode respectively run faster than Python because a JIT compiler compiles bytecode to native code at runtime. CPython cannot have a JIT compiler because the dynamic nature of ... Read More
The isLetterOrDigit() method in Java returns TRUE if the entered value is a letter or digit.We have the following character.char val ='P';Now, let us check for letter or digit using if-else decision-making statement.if (Character.isLetterOrDigit(val)) { System.out.println("Value is a letter or digit!"); } else { System.out.println("Value is neither a letter nor a digit!"); }The following is an example.Example Live Demopublic class Demo { public static void main(String []args) { char val ='P'; System.out.println("Value: "+val); if (Character.isLetterOrDigit(val)) { System.out.println("Value is a letter or digit!"); ...

The arrangement of keys in a typing keypad that we have today is nearly a century and half old. Initially, in the olden days the typewriter machines did have the keys arranged alphabetically but because the machines were too slow in comparison to the speed at which users learned to master them, it presented a different problem.Swift UsersThe users turned out to be way faster than the machines and this resulted in the mechanical character arms getting jumbled up all over. Therefore, the makers of typewriters in response to customer experience and feedback designed a completely new keyboard where the ... Read More
