How to construct array of values in Java

Question

I have to return a JSON string in this format using Spring. My Spring controller will take care of this since I specify the return value as @ResponseBody. Now I have to construct the value in Java in the following format:

["Male", "m"]

Please help me to get this done in Java.

If I understand correctly, you need an object that can be marshalled to json by your spring response provider. Creating a json like array wouldnt help you much if that is the case. — Juned Ahsan

Return String[] or List<String>. Either of these should work.

System.out.println(
       Arrays.toString(new String[] {"Male", "m"})); // prints: ["Male", "m"]

// if the data comes as a dynamic List
String list = Arrays.asList("Male", "m").toString();
System.out.println(list); // prints: ["Male", "m"]

You'd have to use Arrays.toString(Object[]) for the first example.
