To concatenate integers with a string value, you need to use the + operator.Let’s say the following is the string.String str = "Demo Text";Now, we will concatenate integer values with the above string.String res = str + 1 + 2 + 3 + 4 + 5;Example Live Demopublic class Demo { public static void main(String[] args) { String str = "Demo Text"; System.out.println("String = "+str); String res = 99 + 199 + 299 + 399 + str; System.out.println(res); } }OutputString = Demo Text 996Demo Text
This example demonstrate about How to get information about mobile supports data and voice 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 a text view to show information about mobile supports data and voice calls.Step 3 − Add the following code to java/MainActivity.xmlpackage com.example.myapplication; import android.Manifest; import android.content.Context; import android.content.pm.PackageManager; import android.os.Build; import android.os.Bundle; import android.support.annotation.NonNull; import android.support.annotation.RequiresApi; import android.support.v4.app.ActivityCompat; import android.support.v7.app.AppCompatActivity; ...

The highest occurring character in a string is one that occurs most number of times. This can be demonstrated using the following example.String: apples are red The highest occurring character in the above string is e as it occurs 3 times, which is more than the occurrence of any other character.A program that obtains the highest occurring character in a string using C# is given as follows.Example Live Demousing System; namespace charCountDemo { public class Example { public static void Main() { String str = "abracadabra"; int []charCount = ...

Selection Sort is a sorting algorithm that finds the minimum value in the array for each iteration of the loop. Then this minimum value is swapped with the current array element. This procedure is followed until the array is sorted.A program that demonstrates selection sort in C# is given as follows.Example Live Demousing System; public class Example { static void Main(string[] args) { int[] arr = new int[10] { 56, 1, 99, 67, 89, 23, 44, 12, 78, 34 }; int n = 10; Console.WriteLine("Selection sort"); Console.Write("Initial array ...

To compare string for equality in Java, use the equals() method. Let us see some examples wherein we have checked for same as well as different string values.Example Live Demopublic class Demo { public static void main(String[] args) { String one = "x"; String two = "x"; if(one.equals(two)) { System.out.println("String one is equal to two i.e. one==two"); }else{ System.out.println("String one is not equal to String two i.e. one!=two"); } } }OutputString one is equal to two i.e. one==twoLet us see another example.Example Live Demopublic class Demo { public static void main(String[] args) { ...

Insertion Sort is a sorting algorithm that takes an element at a time and inserts it in its correct position in the array. This process is continued until the array is sorted.A program that demonstrates insertion sort in C# is given as follows.Example Live Demousing System; namespace InsertionSortDemo { class Example { static void Main(string[] args) { int[] arr = new int[10] { 23, 9, 85, 12, 99, 34, 60, 15, 100, 1 }; int n = 10, i, j, val, flag; Console.WriteLine("Insertion Sort"); ...
