The java.lang.Math  class has static methods:
  public static int round(float x)
  public static long round(double x)

which round to the nearest integer/long as appropriate.

Alternatively, you can do it "by hand" by adding 0.5 and taking the
floor...it's what Math.round() does for you.  Probably best to use the
library method anyway, as it's already tested and known to work...and
people reading your code will recognise it more easily.

See that API documentation for Math:

Good luck,
Stephen
