Answer:

Technology has a prestigious history. It took years for the technology to come up and prove its essence.

The Internet, World Wide Web, the development of websites, the introduction of Wikipedia and its evolution marks the golden period on 1980s which was followed by launch of certain search engines like google, bing, duckduck go and may more which made the surfing more easy and fun. Then further the launch of android phones and iPhones  brought up another revolution in technology.

Nowadays, technology finds its use almost everywhere. Talking about the classrooms, students resort to internet for exploring studies, topics, projects and much more. The use of Wikipedia has reached a whole new level. Teachers tend to provide assignments over the internet only in order to increase the exposure and reduce the use of paper which works in the collective good of both internet and nature!

{

  public static void main(String args[])

  {

     int count, number, item, arr[];

     

     Scanner console = new Scanner(System.in);

     System.out.println("Enter numbers:");

     number = console.nextInt();

   

     arr = new int[number];

     System.out.println("Enter " + number + " ");

     

     for (count = 0; count < number; count++)

       arr[count] = console.nextInt();

     System.out.println("Enter search value:");

     item = console.nextInt();

     for (count = 0; count < number; count++)

     {

        if (arr[count] == item)

        {

          System.out.println(item+" present at "+(count+1));

         

          break;

        }

     }

     if (count == number)

       System.out.println(item + " doesn't found in array.");

  }

}

Kindly check the first attached image below for the code output.

       {

           int ind = i;

           for (int j = i + 1; j < array.length; j++){

               if (array[j] < array[ind]){

                   ind = j;

               }

           }

           int smaller_number = array[ind];  

           array[ind] = array[i];

           array[i] = smaller_number;

       }

   }

     

   public static void main(String a[]){

       int[] arr = {9,94,4,2,43,18,32,12};

       System.out.println("Before Selection Sort");

       for(int i:arr){
