Answer 1

   public static void main(String[] args) {
    Integer[] bidAmount = {3000, 54000, 2000, 1000, 5600};
    String[] bidderName = {"Jenny", "Mike", "Alvin", "Berry", "John"};
    Map stringTreeMap = new TreeMap<>();
    stringTreeMap.put(bidAmount[0],bidderName[0]);
    stringTreeMap.put(bidAmount[1],bidderName[1]);
    stringTreeMap.put(bidAmount[2],bidderName[2]);
    stringTreeMap.put(bidAmount[3],bidderName[3]);
    stringTreeMap.put(bidAmount[4],bidderName[4]);

    for(Map.Entry entry : stringTreeMap.entrySet()) {
        Integer key = entry.getKey();
        String value = entry.getValue();

        System.out.println(key + " => " + value);
    }
