  • Does this answer your question? [Scanner is skipping nextLine() after using next() or nextFoo()?](https://stackoverflow.com/questions/13102045/scanner-is-skipping-nextline-after-using-next-or-nextfoo) – Johannes Kuhn May 21 '20 at 20:53
  • Happens after you read the first integer, then you read the lines `""`, `"Hong Kong"` and `"India"`, now you ask for an int, but the next token is `USA`. – Johannes Kuhn May 21 '20 at 20:54
  • what are you trying to achieve? , could you please clarify more. – Mahmoud Odeh May 21 '20 at 23:19

You can add values like this and also put value into array:

int no = Integer.parseInt(sc.nextLine());
----------------------------------------
pop[i] =Integer.parseInt(sc.nextLine());

  • Yep, this is the correct solution for my problem. Can you tell me how Integer.parseInt help in taking the input? – Pradeep Pant May 22 '20 at 07:02
  • ``nextLine()`` recognize Enter button and ``nextInt()`` recognize Space button. When you use ``nextInt()`` and press Enter button it gets number but ``nextLine()`` method takes the line before you press enter. Also ``nextInt()`` takes number like this: https://imgur.com/d3LzeBl. – Göksel ÖZER May 22 '20 at 10:21
