如何在Java中将复杂的字符串转换为列表/数组？

Question

I know using myString.split(","); would work if I just had a string separated by commas like "a", "b", "c" , but what if I have a more complicated string like:

["Meal End", "meal-end", "menu", {"color":"black", "width":1}]

I want to separate out the elements

"Meal End"

"meal-end"

"menu"

{"color":"black", "width":1}

My first approach was to get a substring of that whole thing from (1 to string.length - 1). That removed the [ ]. Then I used string.split(",") which almost worked... but for element 3 I end up with {"color":"black" which I do not want.

I want the whole curly brackets object. How can I do this, other than manually searching through the whole string, stopping when I find a {, and continuing when I get to }?

I considered using JSONObject but my string is enclosed in [ ] ... I could always replace those with { } but then there's no key still...

I would suggest "jackson". It parses this string as a list containing 3 strings and 1 map.

List<?> value = (List<?>) new ObjectMapper().readValue(
    "[\"Meal End\", \"meal-end\", \"menu\", {\"color\":\"black\", \"width\":1}]", 
    Object.class);
System.out.println(value.get(0));
Map<?, ?> map = (Map<?, ?>) value.get(3);
System.out.println(map.get("color"));

Output:

Meal End 
black
