Solution
String[] strs = {"apple",...};
Map<String, Integer> map = new HashMap<String, Integer>();
for (String str : strs) {
if (map.containsKey(str)) {
Integer integer = map.get(str);
integer++;
map.put(str, integer);
} else {
map.put(str, 1);
}
}
for (Map.Entry<String, Integer> me : map.entrySet()) {
String strKey = me.getKey();
Integer iCount = me.getValue();
System.out.println(strKey + "出现了" + iCount + "次");
}
