java中map可以按插入顺序倒序输出么？

Question

public class Test {
    public static void main(String[] args) {
        LinkedHashMap<String,String>  a=new LinkedHashMap<String,String>();
        a.put("a", "1");
        a.put("b", "2");
        a.put("c", "3");
        for(String b:a.keySet()){
            System.out.println(b+"值为:"+a.get(b));
        }
        
    }
}

输出为
a值为:1
b值为:2
c值为:3
想要倒序输出怎么实现

public static void main(String[] args) {
    LinkedHashMap<String,String>  linkedhashmap = new LinkedHashMap<String,String>();
    linkedhashmap .put("a", "1");
    linkedhashmap .put("b", "2");
    linkedhashmap .put("c", "3");
    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());  
    }
    
}
