## Exercise 2.27:

## Absolute value

## Objetive:

##
Write a program to calculate (and display) the absolute value of a number x: if the number is positive, its absolute value is exactly the number x; if it is negative, its absolute value is -x.

Do it in two different ways in the same program: using "if" and using the "conditional operator" (?)

## Source Code:

```
import java.util.*;
public class Main
{
public static void main(String[] args)
{
int n, abs;
System.out.print("Enter a number: ");
n = Integer.parseInt(new Scanner(System.in).nextLine());
if (n < 0)
{
abs = -n;
}
else
{
abs = n;
}
System.out.printf("Absolute valor is %1$s" + "\r\n", abs);
abs = n < 0 ? -n : n;
System.out.printf("And also %1$s" + "\r\n", abs);
}
}
```
