You can use the below code to extract the names and their values

    List<String> nameValues = new ArrayList<String>();
    Matcher matcher1 = Pattern.compile("\\\\\"Name\\\\\":\\s\\\\\"[^,}\\]]+\\\\\"").matcher(value);
    while (matcher1.find()) {
        String keyValuePair = matcher1.group();
        String[] keyValue = keyValuePair.split(":");
        String val = keyValue[1].trim();
        System.out.println(keyValue[0]);
        System.out.println(">" + val + "<");
        nameValues.add(val.substring(2, val.length() - 2));
    }
    System.out.println(nameValues);

Here use this one:

public class CStringToCharArray {
 public static void main(String[] args) {
    String testString = "This Is Test";
    char[] stringToCharArray = testString.toCharArray();

    for (char output : stringToCharArray) {
        System.out.println(output);
    }
}
}

You need to first parse this JSON and then iterate through it

After you have parsed this JSON text, then its a matter of iterating through the object and keep pushing the values into arraylist

Once you got the arraylist, then you can convert it to a String array
