I don't know what file you'r referring to, but your program compiles
without error. As for running it... well... it might not do exactly what you
intend (but then again, you haven't said what you intend for it to do).

I'll just point out that your program seems to be expecting the user to
enter in 2 integers in a row, but the prompts displayed to the user give no
indication of this.

In other words, the program asks me to "guess a number", so I do (I
guessed '3'), and then it asks me "Do you think the next number will be
higher HI or lower LO than 3", so I type in "HI", but the program throws an
exception 'cause it was actually expecting me to enter in an integer, as
seen on the line "y = in.nextInt();".
