写一个程序统计输入字符串中以“,”分隔的各种单词出现的次数。例如：输入的字符串为“java,java,j2ee,ibm,j2ee,ibm,j2me,jav

public class Test3 {   
    public static void main(String[] args) throws IOException {
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));   
         //输出提示语   
        System.out.println("请输入字符串 附：字符串之间用,隔开");   
        //读取输入字符串   
        String temp=br.readLine();   
       
        Map maps = new HashMap();   
        String[] templist = temp.split(",");   
        for(int i = 0 ; i < templist.length;i++){
          //准备放map   
            String t = templist[i];   
          //判断key   
            boolean is = maps.containsKey(t);   
            if(is == true){   
          //++1   
                Integer vs = (Integer)maps.get(t);   
                vs++;   
                maps.put(t, vs);   
            }else{   
         //放`1   
                maps.put(t, 1);   
            }   
        }   
        System.out.println(maps);   
    }   
}
