You need to handle the TwitterException that the code of the initializer block can throw, by wrapping it within a try-catch. Adding throws TwitterException in the main method will not solve the problem, because the exception is not thrown within the main method.

{
    try {
        ConfigurationBuilder cb = new ConfigurationBuilder();

        List <Status> status = twitter.getHomeTimeline();
            for(
        Status st:status)

        {
            System.out.println(st.getUser().getName() + "----------" + st.getText());
        }
    } catch(TwitterException ex) {
        ... // handle exception
    }
}

if this is a console application, you can change the code to use a CommandLineRunner (see https://www.baeldung.com/spring-boot-console-app).
