我能够在执行以下代码时获得结果，但我想在字符串数组中存储组成员，但我不这样做。我是java新手可以帮助我。
以下代码

System.out.println(" Person Common Name = " + attributes.get("member")+"\t");

如果您只想存储一个字符串数组，而不知道要存储的字符串数量，请使用ArrayList。

//create the arraylist
ArrayList<String> memberNames = new ArrayList<String>();
// add the memeber name to the array
memberNames.add(attributes.get("member"));
