Ben Peer wrote I keep getting error messages and I just really need help to get it to compile properly then i can at least start getting the bugs out. Forum: Beginning Java. Java Object Oriented Grades Program. Ben Peer. Basically this is it, Friday I have this program due. I've been trying but cannot figure it out so I'm seeking help. The teacher uses the following grade items: 1.

Grade items will be weighted as follows: 1. The final letter grade will be determined as follows: 1. Write a tester class to test your application. Use the constructor to create five students and initialize the instance variables for each student.

Invoke the method to calculate the numeric grade and final letter grade for each student. Thanks if you can help. Nicola Garofalo. Begin with putting lines 23 and 24 inside a method calculate for example.

Jan Cumps. I like Welcome to JavaRanch, Ben. What are these error messages? Try with new. You can place them back where you cut them.

You should write in class Grades the corresponding constructor, because Grades does not know what a call to Grades "Marcus",78,86,87 is in class Grades then write the constructor. In Italy now is and tomorrow i need to wake up early If you don't i will tomorrow.

The last thing. Look at your code. You don't need Basketballs now You need just Grades. It's ok, don't worry. I was just telling you that you wouldn't have found me online for some hours Well, how's your code? Did you solve your problems? If not, can you please post it again with the changes you made?

Campbell Ritchie. Brandon Armstrong, Your post was moved to a new topic. I was born with webbed fish toes. This tiny ad is my only friend:. Boost this thread! Grading Program--Need help, please!!! Grading ProgramHow to write a java program to calculate CGPA percentage. Definition and sample programs are described below about GPA. Check more programs for beginners and interview question and answers here.

A: CGPA is overall grade point average. For each course, there are certain credits which are usually based on how many hours the class is held in each week. A: Your grade point average GPA is calculated by dividing the total amount of grade points earned by the total amount of credit hours attempted.

Your grade point average may range from 0. Here is the simple formula to calculate the GPA Grade point average formula. Standard values are nothing but using the above formula to find the GPA in the below program. For, every code we added three to four different types of outputs so that you will get an idea.

If you have no idea about command line arguments check out here: the Complete Guide. In simple command lines are nothing but giving inputs on the console it itself. Check out the code and output. Output Using command line arguments :. Output Inputs Through Scanner Class :. Check it out! Output User define method :. Sample Program — 5 using class. How to calculate the CGPA and formula?

The problems I think I have right now are: I am not properly utilizing my methods. The getters and setters are probably done wrong. Is it good coding practice to use code separators to separate code for easier viewing? Main question Should the declaring of a students name and grades be inside the student class or was I correct in setting them in the main method?

I think that a student's info name and grades should be kept inside the Student class and that the main method should be using get methods to access them rather than setting them. Is my thinking correct? The basis of what I am trying to achieve is the first comment in my code.

Jonathan Wang Jonathan Wang 83 1 1 gold badge 1 1 silver badge 9 9 bronze badges. Active Oldest Votes. Code separators : I wouldn't recommend using separators like the one you ask about for separating portions of code. IT is not very standard, and the code separation should come from good class and method definitions, and not from artificial elements.

Main Programing Considerations Requirements and Objective: always start with clear objectives and requirements. In your case, I would say from your comments that it is to calculate the average score for your students. This is important because it allows you to focus on what's required, and avoid what's not needed.

Constructor: as you ask in your comments, probably the best way to create a Student is not doing it with a "blank" object, which is what you do when you don't use a constructor to set its initial state. Passing the student name to the constructor would be a better way to initialize this type of object, because there's no point in this particular case to create an instance of Student that has no name and belongs to nobody.

Extensibility: the way things are now, adding a new test would require more code than I would like. Adding 10 tests would require a lot of code. I would approach this using a collection of Test s, and would decide which methods I really need to supply the required functionality. Decomposition: as your comments suggest, each Test can have it's own score and weight. I would create a Test class to keep those attributes I would also consider adding a Name property to identify each test easily in case I decide to print or produce the full Test summary for the Student.

I would choose for which properties I really need to have getters and setters, according to your objectives and requirements.Write ajava program to calculate the grades for a student, using if. I'm in a very giving mood today ; Usually I don't just give the answer to homework problems outright like I am now. I'd rather see some effort put in on your end. So consider yourself very lucky. The following is the pseudocode for the program. Think about what each line means, and then translate it into Java syntax line by line.

For code tags click the button: code when you write your post. Do you really want an infinite loop? Each student has taken five tests, and each test is worth points. The grade is assigned as follows: if the average test score is greater than or equal to 90, the grade is A; if the average test score is greater than or equal to 80 and less than 90, the grade is B; if the average test score is greater than or equal to 70 and less than, the grade is C; if the average test score is greater than or equal to 60 and less than 70, the grade is D; otherwise, the grade is F.

Note that the data consists of student's names and their test scores.

Logic:- First we will ask the user for the total number of the subject after that we will enter marks of all those subjects. Now we will calculate a percentage of marks and print student marks, percentage, and Grade of Student.

Percentage formula is given Below. Explanation:- For this problem, I am taking 5 subjects. Now the first user has to enter a number of the subject of a student after that enter all subject marks and store the marks in an array. Now next step to add or find a sum of all subjects marks entered by the user and apply the formula and print the output calculated by the formula given.

I am trying to make a program that asks the user how many grades they would like to enter.

Then, I want to store the grades the user entered into an array. Finally, I want to find the mean of the grades entered and print out a list of every grade below the mean. As of now, my code calculates the mean of the grades that the user enters but I cannot figure out how to print the grades below the mean. I believe the problem lies in my last for loop but I cannot figure out how to fix it. Also, did I implement the array correctly? Thanks to every who took the time to help me!

You should be counting through ALL the items in the array and then doing an IF to test if it's below the mean and then printing it if it is below the mean.

You have made the loop iterate from 0 up to the mean. You should be interested in student 31 and student You have an array that increments a variable and prints the variable like printing 1,2,3,4,5.

You should figure out what an array is all about rather than worrying about calculating a mean. Your code had some issues. First off your array was being initialized with every iteration for a new grade being entered, which would result in one index since the previous inputs were overriding it. The array scores should be initialized outside the for loop.

Also, your for loop for printing out the grades wasn't correct. You needed to iterate over the scores array and print out each individual value. Learn more. Asked 5 years, 2 months ago.
