Write a method called randomInRange that takes in two numbers representing a range. Print an error message and return zero if the second parameter is less than the first. Otherwise, the method should return a randomly generated integer in that range (inclusive). You may assume that the class has a static Random object called generator already declared and instantiated.

What will be an ideal response?

```
public int randomInRange(int a, int b) {
if(b < a) {
System.out.println("Error, invalid range!");
return 0;
}
return generator.nextInt(b – a + 1) + a;
}
```
