I'm currently "learning" JavaScript + Android Studio for school and I got a little problem for which I can't find the right answer on Google:

I want to know if an int variable has a specific number, for example, I'm looking for the number 7 now int numberOne = 25824 doesn't have a 7 inside, but int numberTwo = 12387 does have one. Is there a way to search for a specific number in int variables?

I tried converting the int into a new string variable, but somehow this doesn't work :(

Here's some code I'm working with:

```
public int round = 1;
public String nummerSieben = "" + round;

button.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {

    if (round % 7 == 0 || nummerSieben.contains("7")==true) {
      ....

    } else {

      ....
    }
  }
});

```

Thank you for your help!
