Question

• 我能够在执行以下代码时获得结果，但我想将组的成员存储在字符串数组中，但我没有这样做。我是java新手，有人可以帮助我。

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

  能够给我组成员，但我想将它存储在字符串数组中。

如果您只想存储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"));
