Answer by Sergey Ponomarev for Sorting domain names

Here is a sample of sorting domains in Golang:

func Test_SortDomain(t *testing.T) {    domains := []string{"a.com", "b.com", "a.a.org", "a.org", "b.a.com"}    slices.SortFunc(domains, CompareDomain)    assert.Equal(t, []string{"a.com", "b.a.com", "b.com", "a.org", "a.a.org"}, domains)}func CompareDomain(a, b string) int {    partsA := strings.Split(a, ".")    slices.Reverse(partsA)    partsB := strings.Split(b, ".")    slices.Reverse(partsB)    return slices.Compare(partsA, partsB)}

You may rewrite it to Java.
