How to round off numbers in an array [duplicate]?

Allen Scott170829-Oct-2014
I cannot find any pattern rounding off doubles in an array. I am trying to make a program that will input a double like grades,money etc., and round it off in a whole number.

Have you tried Math.round() ?

import java.lang.*;
 
publicclassMathDemo {
 
   publicstaticvoid main(String[] args) {
 
      // get two float numbers
      float x = 1654.9874f;
      float y = -9765.134f;
 
      // find the closest int for these floats
      System.out.println("Math.round(" + x + ")=" + Math.round(x));
      System.out.println("Math.round(" + y + ")=" + Math.round(y));
 
   }
}
