身高比较

美团的题，这一题是给了两组数据，一组身高，一组姓名，按照身高升序排列，如果身高相同就按照姓名的字典序进行排序。
调用工具包的思路就是，TreeMap+TreeSet

  1. // 输出B A C D
  2. int[] high = new int[]{176, 170, 176, 176};
  3. String[] name = new String[]{"A", "B", "C", "D"};
  4. Main main = new Main();
  5. main.pz(high, name);
  7. public void pz(int[] high, String[] name) {
  8.     TreeMap<Integer, TreeSet<String>> map = new TreeMap<>();
  9.     for (int i = 0; i< high.length; i++) {
  10.         if (!map.containsKey(high[i])) {
  11.             TreeSet<String> temp = new TreeSet<>();
  12.             temp.add(name[i]);
  13.             map.put(high[i], temp);
  14.         }else {
  15.             TreeSet<String> temp = map.get(high[i]);
  16.             temp.add(name[i]);
  17.             map.put(high[i], temp);
  18.         }
  19.     }
  20.     for (Integer people : map.keySet()) {
  21.         TreeSet<String> names = map.get(people);
  22.         for (String s : names) {
  23.             System.out.print(s+" ");
  24.         }
  25.     }
  27. }
