解析向量字符串转换成字符串？ [英] parse Vector string into a String?

问题描述

我如何能分析一个向量到正常字符串？

How can i parse a Vector to a normal String?

即

矢量newfollowerlist =1，名称2，NAME3，NAME4;

Vector newfollowerlist = "name1, name2, name3, name4";

一旦我输出的矢量字符串，它看起来像这样;

As soon i output the vector string it looks like this;

[name1, name2, name3, name4]

和我想删除[]行的，所以我想到了矢量字符串解析到一个
正常的字符串并删除[]是：

and i want to delete the [] of the line so i thought about parsing the vector string to a normal String and delete the [] by:

String stringWithoutArraySymbols = String VectorHolder.replaceAll("[",""); 
String stringWithoutArraySymbols = String VectorHolder.replaceAll("]","");

我怎样才能真正解析它还是有一个更简单的方法来做到这一点？

How can i actually parse it or is there an easier way to do this?

推荐答案

一个微小的变化

String s = newfollowerlist.toString();
System.out.println(s.substring(1, s.length()-1));

您知道 newfollowerlist.toString（）的格式，因此它很容易得到你想要的格式。如果newfollowerlist是矢量，列表，设置或许多其他类型的集合应该工作。

You know the format of newfollowerlist.toString() so its easy enough to get your desired format. Should work if newfollowerlist is a Vector, List, Set or many other Collection types.
