Level: Easy

```import java.util.Scanner;

public class Math
{
void writeSum(int i, int i2, int i3)
{
// add the body of the method here!
}
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
System.out.print("Enter the first nr: ");
int i = input.nextInt();
System.out.print("Enter the second nr: ");
int i2 = input.nextInt();
System.out.print("Enter the third nr: ");
int i3 = input.nextInt();
Math math = new Math();
math.writeSum(i, i2, i3);
input.close();
}
}
/*
In the following example the user enters 33, 21 and 12
Enter the first nr: 33
Enter the second nr: 21
Enter the third nr: 12

public class Math
{
void writeSum(int i, int i2, int i3)
{
int sum = i + i2 + i3;
System.out.println("The sum is: " + sum);
}
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
System.out.print("Enter the first nr: ");
int i = input.nextInt();
System.out.print("Enter the second nr: ");
int i2 = input.nextInt();
System.out.print("Enter the third nr: ");
int i3 = input.nextInt();
Math math = new Math();
math.writeSum(i, i2, i3);
input.close();
}
