public static void main (String[]args)
{
// creating object to generate random numbers
Random rand = new Random ();
//
Integer arr[] = new Integer[65536];
  
for (int i = 0; i < 65536; i++)
{
//random number in range of 70000
Integer random_num = rand.nextInt (70000);
//if already present, generate new random number and then insert into array
while(Arrays.asList(arr).contains(random_num))
{
   random_num = rand.nextInt (70000);
}
   arr[i] = random_num;
}
//sorting arrays elements
Arrays.sort(arr);
  
for (int i = 0; i < 65536; i++)
{
System.out.println(arr[i]);

}
}
