Write a short snippet of code that converts the first element of the String[] args array to an integer. It should catch an exception and print out a message if the first element cannot be converted to an integer.

What will be an ideal response?

```
int number;
try {
number = Integer.parseInt(number);
}
catch(NumberFormatException nfe) {
System.out.println("The first argument to the command line"
+ " is not an integer; try again.");
System.exit(0);
}
```
