JAVA Assume that there are five classes in a school. Each class has a different size. Class one has 10 students, class two has 2 students, class three has 6 students, class four has 5 students, and class five has 2 student They took math test and got the following results: # student Class 1 Class 2 Class 3 Class 4 Class 5 70.5 90.0 99.9 65.0 44.5 82.3 100.0 85.5 25.4 30.3 75.5 100 88.7 95.6 97.8 55.8 50.0 60.0 39.5 68.4 96.9 |100.0 28.7 55.9 |100.0 1 2 3 4 7 8 9 10 Write a program that calculates the Math average of each class. You should meet the following requirements: • The program should declare a ragged array. • The program should use nested for loop to calculate the math average of each class. • The program only allows two decimal places. (Example 25.99) The result of your program should similar to the following: CA C:\WINDOWSsystem32\cmd.exe Average of class 1: 75.46 Average of class 2: 55.00 Average of class 3: 75.37 Average of class 4: 66.70 Average of class 5: 77.95 Press any key to continue

this is my code, but after automatically check it, it shows smt went wrong(image one) image two is the spec for nextTweet and below is my code, since it's the system automatically  check the code, I dont really have a textcases. plz debug it and fix it. show the screenshot of the code when u finish. thanks  Below is my whole code for TweetBot  import java.util.*;import java.io.*; public class TweetBot {     private List<String> tweets;    private int index;     public TweetBot(List<String> tweets){        if(tweets.size() < 1){            throw new IllegalArgumentException("need contain at least one tweet!");        }        this.tweets = new ArrayList<>(tweets);    }     public int numTweets(){        return tweets.size();    }         public void addTweet(String tweet) {        tweets.add(tweet);        if (tweets.size() == 1) {            // if the tweet was the first one added, set the index to 0            index = tweets.size() - 1;        }    }     public…
