The value of this expression will always be zero: (int) Math.random() Casting to an integer removes the fractional portion. Casting has a higher operator precedence than multiplication or addition, so happens first in your full expression. Parentheses could be used to alter when the cast happens, however. Like this: (int) (Math.random() * 9) + 1
