Prompt the user for data points. Data points must be in this format: string, int. Store the information before the comma into a string variable and the information after the comma into an integer. The user will enter -1 when they have finished entering data points. Output the data points. Store the string components of the data points in a list of strings. Store the integer components of the data points in a list of integers.Ex: Enter a data point (-1 to stop input): Jane Austen, 6 Data string: Jane Austen Data integer: 6

Thank you! but for nextTweet and removeTweet. can u rewrite base on the specs: public String nextTweet() Returns the next tweet from the tweet list. If all the tweets in the list are exhausted, cycle around to the start of the list. For example, the following code snippet should produce the output in the comments. Suppose that tweets stores a list of Tweets ["A tweet about something controversial", "Remember to vote!", "Look at this meme :O"]. TweetBotbot=newTweetBot(tweets); System.out.println(bot.nextTweet()); // A tweet about something controversial System.out.println(bot.nextTweet()); // Remember to vote! System.out.println(bot.nextTweet()); // Look at this meme :O System.out.println(bot.nextTweet()); // A tweet about something controversial Think about how to get the next tweet from the list of tweets, and how you can cycle around to the start once you've gone through all the tweets!
