I need to convert a float number into an integer.
Can Java automatically convert float number into integers? If so, do normal rounding rules apply (e.g. 3.4 gets converted to 3, but 3.6 gets converted to 4)?

You have in Math library function round(float a) it's round the float to the nearest whole number.
int val = Math.round(3.6); \\ val = 4 int val2 = Math.round(3.4); \\ val2 = 3 Comments

I didn't downvote you, but your solution wouldn't even compile, the result of
(int) a + 0.5 is of type double, which can't be assinged to an int have a trycloudy_weather
anyone who knows java with a bit of good sense would realise where the compilation error was before my edit, and would get the logic behind my answer. However, I have edited it and provided a link that shows it working and compiling
Math.round(3.6) would do that for you.
