如何在java中从json数据获取列表

我的Json数据：

{'ID':1,'FirstName':'x','LastName':'y','Company':'x','EMail':'x','PhoneNo':'x'}

public static void main(String[] args) throws IOException {
    String json = getJSON().substring(getJSON().indexOf("[")+1,getJSON().indexOf("]"));
    Users user = new Gson().fromJson(json, Users.class);
    WriteLine("["+user.getID()+"]"+" "+user.getFirstName()+" "+user.getLastName()+" "+user.getCompany()+" "+user.getEMail()+" "+user.getPhoneNo());
}

static void WriteLine(String text){
    System.out.print(text);
}

static String getJSON() throws IOException
{
    URL url = new URL("http://localhost:51679/api/User");
    HttpURLConnection connection = (HttpURLConnection)url.openConnection();

    BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
    StringBuilder sBuilder = new StringBuilder();
    String line;
    while((line = reader.readLine()) != null){
        sBuilder.append(line);
    }
    reader.close();
    connection.disconnect();
    return sBuilder.toString();
}

我的Java代码：

{'ID':1,'FirstName':'x','LastName':'y','Company':'x','EMail':'x','PhoneNo':'x'}

public static void main(String[] args) throws IOException {
    String json = getJSON().substring(getJSON().indexOf("[")+1,getJSON().indexOf("]"));
    Users user = new Gson().fromJson(json, Users.class);
    WriteLine("["+user.getID()+"]"+" "+user.getFirstName()+" "+user.getLastName()+" "+user.getCompany()+" "+user.getEMail()+" "+user.getPhoneNo());
}

static void WriteLine(String text){
    System.out.print(text);
}

static String getJSON() throws IOException
{
    URL url = new URL("http://localhost:51679/api/User");
    HttpURLConnection connection = (HttpURLConnection)url.openConnection();

    BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
    StringBuilder sBuilder = new StringBuilder();
    String line;
    while((line = reader.readLine()) != null){
        sBuilder.append(line);
    }
    reader.close();
    connection.disconnect();
    return sBuilder.toString();
}

但我的json数据如下所示：

{'ID':1,'FirstName':'x','LastName':'x','Company':'x','EMail':'x','PhoneNo':'x'},{'ID':2,'FirstName':'y','LastName':'y','Company':'y','EMail':'x','PhoneNo':'y'}

我有一个错误：由com.google.gson.stream.MalformedJsonException引起：使用JsonReader.setLenient（true）在第1行第136列接受格式错误的JSON

你能帮我吗？对不起，我的英语不好：（

请仔细阅读错误消息。该输入不是有效的JSON，这正是消息告诉您的。字符串和键必须用双引号括起来，而不是单引号：

{"ID":1,"FirstName":"x","LastName":"y","Company":"x","EMail":"x","PhoneNo":"x"}

一个简单的检查也会告诉你同样的情况。或者，正如错误消息方便地告诉你的那样，你可以将阅读器设置为宽容，希望接受格式错误的JSON作为输入
