在Java中，JSONTokener的重要性是什么？

<strong>public class JSONTokener extends java.lang.Object</strong>

import java.io.*;
import org.json.*;
public class JSONTokenerTest {
   public static void main(String args[]) throws JSONException, Exception {
      String jsonStr = "{" + " \"Technology\": \"Java\", "+ " \"location\": [ Madhapur, Hyderabad ] " + "}";
      <strong>JSONTokener </strong>jsonToken = new <strong>JSONTokener(jsonStr)</strong>;
      jsonToken.next();
      jsonToken.next();
      jsonToken.next();
      jsonToken.next();
      char c = jsonToken.<strong>next()</strong>;
      jsonToken.<strong>back()</strong>;
      boolean b = jsonToken.<strong>more()</strong>;
      String s = jsonToken.<strong>nextTo</strong>('i');
      System.out.println("next character: " + c);
      System.out.println("has more tokens: " + b);
      System.out.println("next to i: " + s);
   }
}

<strong>next character: T
has more tokens: true
next to i: Technology": "Java", "locat</strong>
