如何从java获取twitter accessToken？

<dependency>
    <groupId>org.twitter4j</groupId>
    <artifactId>twitter4j-core</artifactId>
    <version>4.0.7</version>
</dependency>

import twitter4j.*;
import twitter4j.auth.*;

public class TwitterAccessTokenExample {
    public static void main(String[] args) {
        String consumerKey = "YOUR_CONSUMER_KEY";
        String consumerSecret = "YOUR_CONSUMER_SECRET";
        
        Twitter twitter = new TwitterFactory().getInstance();
        twitter.setOAuthConsumer(consumerKey, consumerSecret);
        
        try {
            RequestToken requestToken = twitter.getOAuthRequestToken();
            AccessToken accessToken = null;
            
            // 在控制台输出授权URL，并引导用户访问该URL进行授权
            System.out.println("Authorization URL: " + requestToken.getAuthorizationURL());
            
            // 获取用户在授权后返回的PIN码
            // 这里可以通过GUI或者命令行等方式获取用户输入的PIN码
            String pin = "USER_PIN_CODE";
            
            if (pin.length() > 0) {
                accessToken = twitter.getOAuthAccessToken(requestToken, pin);
            } else {
                accessToken = twitter.getOAuthAccessToken();
            }
            
            // 输出获取到的AccessToken和AccessTokenSecret
            System.out.println("Access Token: " + accessToken.getToken());
            System.out.println("Access Token Secret: " + accessToken.getTokenSecret());
        } catch (TwitterException te) {
            te.printStackTrace();
        }
    }
}
