如何遍历HashMap逆序在java问题，怎么解决

Answer 1

案例

//遍历HashMap逆序
public static void main(String[] args) {
LinkedHashMap <String,String > linkedhashmap = new LinkedHashMap<String,String>();
linkedhashmap.put("1","a");
linkedhashmap.put("2","b");
linkedhashmap.put("3","c");
linkedhashmap.put("4","d");
ListIterator<Map.Entry<String,String>> i=new ArrayList<Map.Entry<String,String>>(linkedhashmap.entrySet()).listIterator(linkedhashmap.size());
while(i.hasPrevious()) {
Map.Entry<String, String> entry=i.previous();
System.out.println(entry.getKey()+":"+entry.getValue());
}
}

结果：
