テストに使ったやつです

gistfile1.java

public class PostTester {

  public static void main(String[] args) {
		Twitter twitter = TwitterFactory.getSingleton();
		
		int counter = 0;
		Random rand = new Random();
		while (true) {
			try {
				String text = "@null " + String.format("%x", rand.nextLong());
				Status status = twitter.updateStatus(text);
				++counter;
				System.out.println(counter + "回目: " + status.getText());
				//ひとやすみ
				try {
					Thread.sleep(1000);
				} catch (InterruptedException e) {
					e.printStackTrace();
				}
			} catch (TwitterException e) {
				e.printStackTrace();
				break;
			}
		}
		System.out.println("投稿した回数 :" + counter);
	}

}
