Wow! Cool! But for some reason it does not work when checking. ) Maybe you need to import something? )))))))))

Yes, Chrono79, you are right) I corrected the code and everything worked)

Thank you, Chrono79, I will look again closely)

Unfortunately, kata does not work correctly:

@Test
public void test5() {
assertEquals(0, Kata.TripleDouble(451999277L, 411777228L));
}

@Test
public void test6() {
  assertEquals(0, Kata.TripleDouble(1112L, 122L));

I corrected to 0 to 1.
@Test
public void test5() {
assertEquals(1, Kata.TripleDouble(451999277L, 411777228L));
}

@Test
public void test6() {
  assertEquals(1, Kata.TripleDouble(1112L, 122L));
}

After that, the tests worked successfully.
But by clicking "ATTEMPT" an error test 6 appeared and I can not control it.
