Given these methods below how would we make a new method to get it to list the siblings of a person?

public static void showPaternal(Person person) { System.out.println("Paternal line:"); int level = 1; while (person!= null) { for (int i = 0; i < level; i++) System.out.print(" "); System.out.println(person.getName()); person= person.getFather(); level++; } }

public static void showMaternal(Person person) { System.out.println(" Maternal line:"); int level = 1; while (person!= null) { for (int i = 0; i < level; i++) System.out.print(" "); System.out.println(person.getName()); person= person.getMother(); level++; } }

public static void showChildren(Person person) { ArrayList kids = person.getChildren(); System.out.println("Children:"); if (kids.size() == 0) { System.out.println(" none"); } else { for (Person kid: kids) { System.out.println(" " + kid.getName()); } } }
