How to round up a floating-point number in Java

Question

public class MyClass {
    public static void main(String args[]) {
      double x=120.38;
      System.out.println(Math.round(x‬));
    }
}

Output: 120

But I want an output of 121 Rounding off any decimal values to 1 whole number

*"[Rounding off](https://en.wiktionary.org/wiki/round_off)"* To almost everybody, that means rounding to **nearest** number, and `120` is the nearest whole number to `120.38`. Did you perhaps mean you want rounding **up**? Perhaps it would be a good idea to check the javadoc of [`RoundingMode`](https://docs.oracle.com/javase/8/docs/api/java/math/RoundingMode.html) to learn the Java terminology used for naming the various rounding modes: Up, Down, Ceiling, Floor, Half-Up (aka "round off"), Half-Down, and Half-Even (aka "Banker's rounding"). — Andreas, Feb 07 '20 at 03:27
