您可以尝试像这样：

  Gson gson = new Gson（）; 

 Type type = new TypeToken< HashMap< String，String>>（）{}。getType（）; 

 HashMap< String，String> map = new HashMap< String，String>（）; 
 map = gson.fromJson（json，type）; 
 

其中json是您定义的json字符串。

I'm not very familiar with Java, but got the job to reverse the following JSON-Output to a JAVA object-structure:

Sample:

{"MS":["FRA",56.12,11.67,"BUY"],"DELL":["MUC",54.76,9.07,"SELL"]}

Does someone know, how to build the Arrays / Objetcs and the code to read the strings with Java? JSON or GSON codesamples are welcome.

Thanks!

You could try something like:

Gson gson = new Gson();

Type type = new TypeToken<HashMap<String, String>>(){}.getType();

HashMap<String, String> map = new HashMap<String, String>();
map = gson.fromJson( json, type );

Where "json" is the json string you defined.
