This example demonstrate about How to get street 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 street information.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; ...

Proper security involves all-around surveillance or observation of people, their behavior and actions, immovable property like land and building as well as movable property stationed there. Surveillance is generally conducted with the help of methods that either have limited mobility or are stationary like, CCTV cameras, GPS tracking dependent on satellite connectivity and not helpful in close observation, stake-outs, which are time-consuming, data-based profiling and biometrics and some other methods.Drone Has Turned the TableAll these methods have their own level of advantages and limitations but when it comes to drone technology, the efficiency, and effectiveness of any security operation increase ...

The following is our string.String str = "Tutorial";Now, use the toCharArray() method to convert string to char array.char[] ch = str.toCharArray();Now let us see the complete example.Example Live Demopublic class Demo { public static void main(String []args) { String str = "Tutorial"; System.out.println("String: "+str); char[] ch = str.toCharArray(); System.out.println("Character Array..."); for (int i = 0; i < ch.length; i++) { System.out.print(ch[i]+" "); } } }OutputString: Tutorial Character Array...

To compare two Java char arrays, use the Arrays.equals() method.Let us first declare and initialize some char arrays.char[] arr1 = new char[] { 'p', 'q', 'r' }; char[] arr2 = new char[] { 'p', 'r', 's' }; char[] arr3 = new char[] { 'p', 'q', 'r' };Now let us compare any two of the above arrays.Arrays.equals(arr1, arr2));In the same way, work it for other arrays and compare them.The following is an example.Example Live Demoimport java.util.*; public class Demo { public static void main(String []args) { char[] arr1 = new char[] { 'p', 'q', 'r' }; ...

To determine if a String is a legal Java Identifier, use the Character.isJavaIdentifierPart() and Character.isJavaIdentifierStart() methods.Character.isJavaIdentifierPart()The java.lang.Character.isJavaIdentifierPart() determines if the character (Unicode code point) may be part of a Java identifier as other than the first character.A character may be part of a Java identifier if any of the following are true.it is a letterit is a currency symbol (such as '$')it is a connecting punctuation character (such as '_')it is a digitit is a numeric letter (such as a Roman numeral character)Character.isJavaIdentifierStart()The java.lang.Character.isJavaIdentifierStart() determines if the character (Unicode code point) is permissible as the first character in a Java ...

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
