## Try this code:

```
Collections.sort(categories, (a, b) -> {    if (a.id != b.id)
{        if (a.id ==-1) {            return -1;        }        if (b.id ==-1) {            return 1;        }        if (a.id == 0)
{            return -1;        }        if (b.id == 0)
{            return 1;        }    }    return a.name.compareTo(b.name);});
```
