Java Program to print distinct elements from array,

  n=in.nextInt();
  int arr[]=new int[n];
  for(i=0;i<n;i++)
  {
   System.out.print("Enter Element "+(i+1)+": ");
   arr[i]=in.nextInt();
  }
  
  
  for(i=0;i<n;i++)
  {
   for(j=i+1;j<n;j++)
   {
    if(arr[i]>arr[j])
    {
    temp=arr[i];
    arr[i]=arr[j];
    arr[j]=temp;
    }
    
   }
  }
  
  
  
  while(value!=n)
