Answer 1

You should change next() to nextInt(), but the program will crash anyway if you enter a wrong password. The playground doesn't support repeating inputs in a loop.

Answer 2

"so" is an integer, but next() returns a string.

Answer 3

you can test such a loop using multiline input (on SL) :
1000
2000
8819

Answer 4

It works normal in Jvdroid.

Answer 5

Thanks to all to solve my problem
