如何为列表中的每个字符串添加或插入'(单引号),其中使用Java用逗号分隔字符串 [英] How to add or insert ' (single quotes) for every string in a list in which strings are separated by commas using Java
问题描述
我有一个如下列表
[url1,url2,url3,url4]
此列表将基于HTML下拉列表中的多项选择.因此列表大小,即列表元素是动态变化的.我的问题是我无法获得为字符串加上单引号的逻辑. 我希望上面的字符串列表显示为
This list will be based on multiple selection from drop down list of HTML. So list size i.e., list elements change dynamically. My problem is I am unable to get the logic for getting single quotes to the strings. I want the above string list to be displayed as
'url1','url2','url3','url4'
即每个字符串的单引号('
)和逗号(,
)都不应消除.请帮助我如何使用Java实现此功能.
That is single quotes ('
) for each string and commas (,
) should not be eliminated. Please help me how to achieve this using Java.
推荐答案
-
迭代列表(持续/同时).
Iterate the list (for/while).
对于列表中的每个元素,请附加<element-of-list>
.提示:在StringBuilder
上使用append()
.
For each element in the list append <element-of-list>
. Hint: use append()
on StringBuilder
.
截断/子串列表以删除最后添加的元素.提示:在String
类上使用子字符串.
Truncate/substring the list to remove the last element added. Hint: use substring on String
class.
