i expect..please suggest the best way to get that

here i tried some methods


Get get_colums=new Get(ROWKEY);

Result result_of_coumns=testTable.get(get_colums);


    Map    <byte[],byte[]>
family=result_of_coumns.getFamilyMap(colmnfamily);

    for (Map.Entry<byte[],byte[]> entry:family.entrySet())
    {
        System.out.println(entry.getKey());
        System.out.println(entry.getValue());
    }


O/P

[B@e577d32


LiST METHOD


List <String> mail_list = new ArrayList<String>();

Result result_of_coumns=testTable.get(get_colums);

for(Byte kv:result_of_coumns.getRow())
    {
System.out.println(kv.toString());
mail_list.add(kv.toString());

    }

for(String temp:mail_list)
    {
