# Algorithm to get the submultiples of each number in a range

I have this exercise in mind, I keep trying to solve it in Java but I’m not able to create a correct algorithm to get the submultiples of each number in a range, the start and the end of the range is user defined. Besides, the number 1 doesn’t count as a submultiple.

For example, in a range between 3 and 9, the output of the app would be:

```start: 3
end: 9

Submultiples of 3:  Doesn't have submultiples
Submultiples of 4:  2
Submultiples of 5:  Doesn't have submultiples
Submultiples of 6:  3 2
Submultiples of 7:  Doesn't have submultiples
Submultiples of 8:  4 2
Submultiples of 9:  3
```

It would be very helpful if someone can help me with this exercise. Thanks for reading!

You can do it using to nested loops, like this:

```class HelloWorld {
public static void main(String[] args) {
int start = 3;
int end = 9;
boolean foundMultiples = false;
for(int i=start; i<=end; i++) {
foundMultiples = false;
System.out.print("Submultiples of " + i + ": ");
for(int j = 2; j < i; j++) {
if(i % j == 0) {
foundMultiples = true;
System.out.print(j + " ");
}
}
if(!foundMultiples) {
System.out.print("Doesn't have submultiples");
}
System.out.println();
}
}
}
```

Here, we loop through the user entered range, and then found multiples of each number in an inner loop. We keep track of if any multiple was found, using a boolean variable.
