Implement/build Binary Search Tree for a given data set

Another common interview questions to implement or build Binary Search Tree from the given dataset using Java.
Dataset: [10, 7, 16, 12, 5, 11, 2, 20, 1, 14]

import java.util.Scanner;

class BinarySearch 
{
  public static void main(String args[])
  {
    int c, first, middle, last, n, search, array[];

    Scanner in = new Scanner(System.in);
    System.out.println("Enter number of elements");
    n = in.nextInt(); 
    array = new int[n];

    System.out.println("Enter " + n + " integers");

    for (c = 0; c < n; c++)
      array[c] = in.nextInt();

    System.out.println("Enter value");
    search = in.nextInt();

    first  = 0;
    last   = n - 1;
    middle = (first + last)/2;

    while( first <= last )
    {
      if ( array[middle] < search )
        first = middle + 1;    
      else if ( array[middle] == search ) 
      {
        System.out.println(search + " found at " + (middle + 1) + ".");
        break;
      }
      else
         last = middle - 1;

      middle = (first + last)/2;
   }
   if ( first > last )
      System.out.println(search + " is not present.\n");
  }
