Hi, started programming 2 days ago, and i'm having a problem with Java saying one of my variables isn't initialised. Couls someone help please?! Thanks, code below:

```
public static void adding()
{
int n = getN();
int total;
for (int i=1; i<=n; i++)
{
total = i + 1;
}
System.out.println(total);
}
public static int getN()
{
String input = JOptionPane.showInputDialog(null,
"How many numbers would you like to add up?");
int n = Integer.parseInt(input);
return n;
}
```

and the error code:

```
adding.java:22: error: variable total might not have been initialized
System.out.println(total);
^
1 error
```

I'm trying to create a program that asks for a number (n) and then the program adds all the numbers up to n (e.g. 1 + 2 + 3 etc.). Thanks!
