Then, find the minimum number in the array and its index.

2-

Write a program that takes input of names from user. Print total names number and all names.
NOTE: Solve this problem using ArrayList and Enhanced For Loop.
Typical run of the program:
Enter a name: (Q to exit)
Ali
Enter a name: (Q to exit)
Sarah
Enter a name: (Q to exit)
David
Enter a name: (Q to exit)
Ahmad
Enter a name: (Q to exit)
Jhon
Enter a name: (Q to exit)

Scenario1.java
import java.util.Arrays;
import java.util.Random;

/**
* @author Srinivas Palli this class fills an array of size 50 with random numbers
* between 0 and 100. Then, find the minimum number in the array and its
* index
*/
public class Scenario1 {

   /**
   * @param args
   */
   public static void main(String[] args) {
       // TODO Auto-generated method stub

       int randomArray[] = new int[50];

       Random random = new Random();
       int Low = 0;
       int High = 100;

       for (int i = 0; i < 50; i++) {

           randomArray[i] = random.nextInt(High - Low) + Low;
       }
       System.out.println(Arrays.toString(randomArray));

       int minIndex = 0, minNumber = randomArray[0];

       for (int i = 1; i < 50; i++) {

           if (randomArray[i] < minNumber) {
               minNumber = randomArray[i];
               minIndex = i;
           }
       }
       System.out.println("Minimum Number :" + minNumber
               + " Minimum Number Index :" + minIndex);

   }

}

OUTPUT:
[28, 63, 20, 30, 59, 69, 88, 40, 17, 64, 69, 59, 84, 40, 1, 7, 21, 43, 47, 3, 30, 59, 24, 6,
46, 30, 94, 33, 8, 56, 86, 22, 89, 89, 6, 3, 32, 73, 72, 86, 89, 82, 59, 97, 43, 3, 4, 30,
78, 34]
Minimum Number :1 Minimum Number Index :14

               String name = scanner.nextLine();
               if (name.equalsIgnoreCase("Q")) {

                   break;
               } else {

                   arrayList.add(name);

           } while (true);

           System.out.println("You entered " + arrayList.size()
                   + " names which are:");

           for (String name : arrayList) {

           }
       } catch (Exception e) {
           // TODO: handle exception
       }
   }

OUTPUT:
Enter a name: (Q to exit)
