The goal for Lab06b is to use the provided Student class (ATTACHED IN IMAGE) and create an array of Student objects that are stored in a School object. This program uses a Student class that is provided and shown below. The class is placed in its own separate file and should not be altered. This program sequence started with Lab06a. It is a reminder that it is the same Student file used by Lab06a. This lab will add data processing to the earlier Lab06a. This program will continue with the Lab06b program that performs some data processing on the Student records. For this lab 10 Student objects need to be constructed and placed in a students array, which is stored in a School object. You actually did this already for Lab06a. You also need to complete the School constructor, addData method and toString Method, which were in Lab06a. Feel free to just copy them over. You need to complete three bubbleSort methods; one that sorts according to the student gpa., one for age and one for name.…

/*TASK 5. Implement part 1 of the report. You need to read data from input.txt file, store it into array of items (called items) and write it in a formatted form to the output file. Code, debug and present it in the best possible format. Hint: It might be helpful to format the String coming from toString( ) method using String.format( ) method, which works similar to System.out.prinf. Hint2: You might have to close and delete existing output .doc or .txt file from its folder * public class YourUserName_hw7 { static Item [ ] items = new Item [200];//an array of Items static EdibleItem [ ] edibleItems;//an array of Edible Items static int countEdibleitems = 0;//count edible items static String pageHeader; //save the header //main( ) method runs the program public static void main(String[ ] args) throws FileNotFoundException { double sum = 0, average = 0; //Optional - create a new input file //CreateInput.createInputFile( );…

Write a program that reads a list of enrollments from a file and prints a class roster for the teacher. Make the class roster line up as neatly as you can and still fit on the screen. You can choose the actual values to use for your data. Make sure to do enough sets of data to well test your program! (Empty data set, normal data set, data with large values, data with short values, etc.) Also, your program can't know ahead of time how many people are enrolled in the class... Don't forget to read the file's name from the user and protect your program against any errors that may occur during the opening of the file. Try to use functions to break up the program into more manageable pieces. USING C++ As an example, you might have the data file contain:
