Hello, I have a class teams where they have scores (int), winning number (int), defeats (int) etc. Within the method main, I have an array of 20 teams and need to sort them by the score, if the score is equal I check who has the most wins and need to print it on the screen. If anyone can help I’d be grateful.

Try to use the method Arrays.sort(T[], Comparator<? super T>) thus:

Time[] times = ...;
Arrays.sort(times, (a, b) -> {
   int pa = a.getPontos();
   int pb = b.getPontos();
   return pa == pb ? a.getVitorias() - b.getVitorias() : pa - pb;
});

Just make sure before there is no element null in the array, or else this code will give a NullPointerException.

At the end, to print the names, after ordering, just use a for simple and print the names of teams one by one.
