ArrayList

当前，输出是这样的

List<String> list11 = new ArrayList<String>(Arrays.asList(abc.split(" , ")));

我想要这样的输出：

"subCategory": ["\"a\"", "\"b\"","\"c\""],`

2 个答案:

答案 0 :(得分：1)

给出String abc="\"a\",\"b\",\"c\"";

您可以在使用String之前简单地替换split()中的引号：

 List<String> list11 = new ArrayList(Arrays.asList(abc.replace("\"", "").split(",")));

输出： 

[a, b, c]

答案 1 :(得分：0)

您的字符串必须类似于以下格式，以便您轻松获得 [“ a”，“ b”，“ c”] 

String abc="\"a\""+","+"\"b\""+",\"c\"" ;
List list11 = new ArrayList(Arrays.asList(abc.split(" , ")));
System.out.println(list11);
