JAVA给定字符串数组返回数组各值（Map按照Key排序）

public static Map<String, Integer>publicMap = new LinkedHashMap<String,Integer>();

    publicstatic void main(String[] args) {        String str = "b|c|d|e|f|a|b|c|d|e|a|a";//从数据库循环累加标签

       String[] ss = str.split("\\|");        System.out.println(getTopMap(ss, 10).toString());     }

    privatestatic Map<String, Integer>getTopMap(String[] strs, int topCount) {        Map<String, Integer> map = newLinkedHashMap<String,Integer>();        for (String s : strs){              //存到Map中 key:名字 value:次数            if (publicMap.containsKey(s)) {  //包含则 value+1                publicMap.put(s, publicMap.get(s) + 1);            } else {                publicMap.put(s, 1);            }        }

       String setStr = publicMap.keySet().toString();        String[] keys = setStr.substring(1,setStr.lastIndexOf("]")).split(",");

       sortKeyByValues(keys);//按照value对key进行最值排序

       int count = topCount > keys.length ? keys.length :topCount;

       for (int i = 0; i < count; i++) {            map.put(keys[i].trim(), publicMap.get(keys[i].trim()));        }        return map;     }    //按照value对key进行最值排序

    privatestatic void sortKeyByValues(String[] keys) {        boolean isSwap = true;        String temp;        String key1;        String key2;        int value1;        int value2;

       for (int i = 0; i < keys.length&& isSwap; i++) {            isSwap = false;            for (int j = 0; j < keys.length - 1; j++) {                key1 = keys[j + 1].trim();                key2 = keys[j].trim();                value1 = Integer.parseInt(publicMap.get(key1).toString());                value2 = Integer.parseInt(publicMap.get(key2).toString());                if (value1 > value2) {                    temp = keys[j].trim();                    keys[j] = keys[j + 1].trim();                    keys[j + 1] = temp;                    isSwap = true;                }            }        }     }
