Question

我需要将TreeMap转换为数组;任何人都可以告诉我它是如何完成的？我需要这两个键和values.I我在一个文本文件

这里映射每个单词的频率输出：

{about=1, administrators=1, ago=1, and=1, around=1, asking=1, at=2, blocked=1, by=1, com=1, device=1, either=1, filtering=1, freerk=1, get=1, helps=1, hope=1, i=1, long=1, not=1, or=2, remember=1, school=1, sites=1, so=1, some=1, someone=1, that=1, the=1, this=1, to=1, view=1, was=1, ways=1, web=1, were=1, work=1, www=1, zensur=1} 

Answer 1

StringBuilder temp=new StringBuilder(); 

    for(Map.Entry<String,Integer> entry : treeMap.entrySet()) 
    { 
     String key = entry.getKey(); 
     Integer value = entry.getValue(); 

     temp.append(key).append(" = ").append(value).append(", "); 
    } 

    //TODO remove the last comma 

String result=temp.toString(); 

Answer 2

不要使用TreeMap中，使用番石榴的TreeMultiSet。

String[] str = new String[treeMultiSet.size()]; 
int ct = 0; 
for(MultiSet.Entry<String> entry : treeMultiSet.entrySet()){ 
    str[ct++] = entry.getElement() + "=" + entry.getCount(); 
}
