Map或Hashtable的value排序

我们在文本操作时，经常要用到排序 以下是我写的一个供大家参考：

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Map.Entry;

public class WordSort {
	public static void main(String args[]) throws IOException{
		Map<string, integer=""> wordCount=new HashMap<string, integer="">();
		//需要排序的文本
		BufferedReader buufBufferedReader=new BufferedReader(new InputStreamReader(new FileInputStream("D:\\钱洋个人\\学术中心\\数据处理\\user_content_count.txt"), "utf-8"));
		String line=null;
		while((line=buufBufferedReader.readLine())!=){
			wordCount.put(line.split()[], Integer.valueOf(line.split()[]));
		}
		buufBufferedReader.close();
		System.out.println(+wordCount.size());
		
		    (  (  (  ()),));
		 (Map.Entry<string, integer=> j: wordCount.entrySet()) {
			   j.getValue();
			 (value==) {
				Writer.append(j.getKey()+);
			}
        }
		Writer.close();
		
        List<map.entry<string, integer=>&gt; list =  <map.entry<string, integer=>&gt;(wordCount.entrySet());
        Collections.sort(list,  <map.entry<string, integer=>&gt;() {
            
               {
                
                 o2.getValue().compareTo(o1.getValue());
            }
        });
        
            (  (  (  ()),));
         (   ; i &lt; list.size()*; i++) {
        	Writer1.append(list.get(i).getKey()+);
		}
        Writer1.close();

	}
}

```</string,></string,></map.entry<string,></map.entry<string,></map.entry<string,></string,></string,></string,>
