Go to your already created application (https://dev.twitter.com)
Check your application settings (> Application Type)
'Application Type' need to be one of Read, Write and Access direct messages. If not you can easily make an update.
转到您已经创建的应用程序 (https://dev.twitter.com)
检查您的应用程序设置（> 应用程序类型）
“应用程序类型”需要是读取、写入和访问直接消息之一。如果没有，您可以轻松进行更新。
(I tested your code in processing environment and it is working)

First of all , regenerate your acces token/secret and consumer key/secret. Then try this.
首先，重新生成您的访问令牌/秘密和消费者密钥/秘密。然后试试这个。
String consumerKey = "yourconsumerKey ";
String consumerSecret = "yourconsumerSecret";
String accessToken = "yourAccessToken";
String accessSecret = "yourAccessSecret";
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
.setOAuthConsumerKey(consumerKey)
.setOAuthConsumerSecret(consumerSecret)
.setOAuthAccessToken(accessToken)
.setOAuthAccessTokenSecret(accessSecret);
try
{
TwitterFactory factory = new TwitterFactory(cb.build());
Twitter twitter = factory.getInstance();
System.out.println(twitter.getScreenName());
Status status = twitter.updateStatus(latestStatus);
System.out.println("Successfully updated the status to [" + status.getText() + "].");
}catch (TwitterException te) {
te.printStackTrace();
System.exit(-1);
}

Statuscode 401 means you're not authorized
状态码 401 表示您 未被授权
Check if your credentials are valid. If they are, maybe your application has not been validated by the user. See the examples on twitter4j site(point 7)
检查您的凭据是否有效。如果是，则可能您的应用程序尚未得到用户的验证。请参阅twitter4j 站点上的示例（第 7 点）
