How to Convert String to List<String> in Java Without using Jackson Api

Question

I need to convert String to List in Java without using Jackson Api. My String is like

String abc = "[\"A\",\"B\",\"C\"]";

I want it to convert into List.

I already have net.sf.json and org.json.simple imported.

I can not use Jackson API but is there any other way to do this instead using split?

Answer 1

Since you have org.json.simple you can use JSONParser to parse the JSON

String abc = "[\"A\",\"B\",\"C\"]";
JSONParser parser = new JSONParser();
Object obj = parser.parse(abc);

Answer 2

In case you have only given json string format ["A","B","C"] then you can manually parse it:

public static List<String> parse(String str) {
    List<String> res = new ArrayList<>();
    int pos = str.indexOf('[') + 1;

    while ((pos = str.indexOf('"', pos)) >= 0) {
        int beginIndex = pos + 1;
        int endIndex = str.indexOf('"', beginIndex);
        res.add(str.substring(beginIndex, endIndex));
        pos = endIndex + 1;
    }

    return res;
}
