Grade point average
Hello,
The problem: This is a calculator type of script and I am
going nowhere... I want to convert the grade, example A,A+,B,B+into
a numeric form. Like A+ is equivalent to 4 and the conversion
appear automatically. I have to input a credit and it automatically
multiplies with the given numeric grade to another.
Please help!
Does this help?
function gradeToNum(grade:String):Number {
var baseGrades = {A:4,B:3,C:2,D:1,F:0};
var gpa = baseGrades[grade.charAt(0)];
gpa = grade.charAt(1) == "+" ? gpa += .5 : gpa;
gpa = grade.charAt(1) == "-" ? gpa -= .5 : gpa;
return gpa;

What is meant by " Grade Point Average "?The following answer is correct?
what is meant by " Grade Point Average "?
Grade Point Average = grades for assignments and then using the points/grades of classes. Is it correct?
Thanks and Regards
mohideenGrade Point Average (GPA) is typically a term used in upper schools and universities. It is the average of the grades of all your classes. 4 is the top GPA.

Could anyone help me out?
Print the msg "Accept" if the student has any of the following:
* A grade point average of 3.0 or above and admission test score of at least 60
* A grade point average of below 3.0 and an admission test score of at least 80.If the student doesn't meet either of the qualification criteria, print "Reject"

Programming project: does this code look clean enough to turn in?
Hi, i was just wanting to know people's opinion on the format of my classes below, i haven't done much java programming and I just want to make sure that this program is easily understood. I will not be able to respond, because I have to wake up in 3 hours for school. So thanks in advance, I will be reading this tomorrow, to see your suggestions, thank you.
here is the scholar class, it is the class that i made to create a scholar(student object) that will be applying for a scholarship and the grades are entered in the ScholarTester class.
I could've done things differently and easier but the professor strictly called for it to be exactly as he stated. I came up with a better, less tedious way, but i couldn't use it. My way was to create a method to randomly generate grades and values to determine the major, but my prof. saw it and made me implement everything in ScholarTester. Also neither of the students will receive the scholarship, that will be determined in project 2 my professor said.

}Thanks for reading this long and boring project.On comments: don't include a comment that just repeats syntax:
// constructor for a Scholar object
public Scholar(String myFullName, ...Anyone knowing Java syntax doesn't need that comment and gains nothing
from its presence, and anyone not knowing Java syntax shouldn't be reading
a listing.
On parameter names: a isn't very imaginative or prescriptive. (See next code.)
On setters returning the argument:
public int setCreditHours(int creditHours ){
this.creditHours = creditHours ;
return creditHours;
}1. Most people keep it simple and use a void return type.
2, The next most common convention is to return this:
public Scholar setCreditHours(int creditHours){
this.creditHours = creditHours ;
return this;
}Then you can chain calls, which is occasionally useful:
scholar.setCreditHours(4).setEssayScore(2);3. If you insist on returning the argument, note that this is a one-liner:
public in setCreditHours(int creditHours){
return this.creditHours = creditHours ;
} -

}everything runs like it should and the program is doing fine, i just need to change the format of the Scholar constructor and probably other things. Can someone please give me an idea how to fix this.
Thanks for taking your time reading this.then don't reply if you're not going to read it, i
just gave the url, Don't get snitty. I'm just informing you that most people here don't want to click a link and read your whole bloody assignment. If you want help, the burden is on you to make it as easy as possible for people to help you. I was only trying to inform you about what's more likely to get you help. If doing things your way is more important to you than increasing your chances of being helped, that's your prerogative.
so you can get an idea on what
it's about, and yeah i know how to add a constructor,
that's very obvious, That's what I thought, but you seemed to be saying, "How do I add this c'tor?" That's why I was asking for clarification about what specific trouble you're having.
i just want to know how to
implement everything correctly, so don't start
flaming people. I wasn't flaming you in the least. I was informing you of how to improve your chances of getting helped, and asking for clarification about what you're having trouble with. -

Could every one help me with this? Thanks
2. a. Write a program that prompts a professor to input grades for five different courses for 10 students. Prompt the professor to enter one grade at a time using the prompt �Enter grades for student #1� and �Enter grade #1�. Verify that the professor enter only A, B, C, D, or F. Use variables for the student numbers (1 through 10) and grade numbers (1 through 5). The class name is GradePoint.
b. Modify the GradePoint program so that it calculates the grade point average (GPA) for each student. A student receives four grade points for an A, three grade points for a B, two grade points for a C, one grade point for a D, and zero grade point for an F. Store the grades and points in parallel arrays. Search the arrays to determine the points for the grade. Store the GPA for each student in another array. (Hint: Copy the GPA for each student to a different array by initializing the new array with GPAs from the other array.)
c. Display the GPA scores from each of the two GPA arrays to verify that the GPAs were copied correctly. Identify which array the scores are from.I got A. but I don't know how to do B and C
could everyone help me how to do B and C?

hi everyone!
could you please help me with this exercise?
i have one error message, but i can't solve it.
- create a project named Student. Add fields to the Student class for an ID number, number of
credit hours earned, and number of points earned. include methods to assign values to all fields.
The Student class also has a field for grade point average. include a method to compute the grade
point average field by dividing points by credit hours earned.write methods to display the values
in each Student field.
here goes my coding:
public class Student
int idNo = 111;
double hrs = 0;
double noOfPoints = 0;
double grPoAve = 0;
public void setNoOfPoints(double nrPoints)
noOfPoints = nrPoints;
public double getNoOfPoints()
return noOfPoints;
public void sethrs(double hours)
hrs = hours;
public double gethrs()
return hrs;
public double calcAverage(double points, double hours)
double grPoAve = points/hours;
return grPoAve;
public void setcalcAverage(double gpa)
grPoAve = gpa;
public double getcalcAverage()
return grPoAve;
public void setidno(int idNumber)
idNo = idNumber;
public int getidno()
return idNo;
public static void main (String[] args)
Student stnew = new Student();
stnew.setNoOfPoints(555);
stnew.sethrs(2);
double grPoAve;
grPoAve = calcAverage(stnew.getNoOfPoints(),stnew.gethrs());
System.out.println("The student with number: " + stnew.getidno());
System.out.println(" has " + stnew.gethrs() + "hours");
System.out.println(" has accumulated " + stnew.getcalcAverage());
System.out.println(" grade point average ");
- if i use the above code i am getting this error:
cannot reference member 'double calcAverage(double points, double hours)' without an object.
the error message points to the fifth line in the main method.
error message:
not enough arguments for method 'void Student.SetNoOfPoints(double nrPoints)'
- if i use the following :
grPoAve = calcAverage(stnew.setNoOfPoints,stnew.gethrs);
i am getting this error:
'stnew.setNoOfPoints' is not a field in class 'Student'
help me please.

Hi All,
I wanted to calculate GPA and CGPA. As far as my knowledge goes its a standard functionality delivered by SLcM. We have to just make sure that we have done the right configuration to assign the performance indices to particular Calculation Point.
In my case i have created 4 performance indeces and assigned PI calc as given below:
Attempted Credits == CPA1 (Total attempted credit)
Earned Credits== CPE1 (Total earned credits)
Grade Point Average== GPA1(Average Grade) Filter=== Appraisal completed
Cummulative Grade Point Average== GPA1(Average Grade) Filter=== Average Grade
I just wanted to know which PI calculation shall be assigned to GPA and CGPA? Whether assigned filters are correct or not?
Is it necessary to assign parameters and filters to Performance Index?
Regards
Vinod KumarVinod, the PI to use for Sessional GPA and Cumulative GPA is the same: GPA. For the first one (Sessional GPA) you should be filtering by academic year/session and by the "Appraisal complete" if you want (yo are already using that filter).
The Cumulative GPA should use the same PI (GPA), and filter just by "Appraisal complete" (in your scenario).
You should check that the GPA PI standard calculation (the one provided by SAP) fits into your client's GPA calculation requirements. If it doesn't, you should copy that PI and make the necessary changes.

Hi. Can anyone help me write a Java program that ask the user to input their class and the grade they think they will get in each class. Then find the grade point average for that user. it needs to use JOptionPane and display the classes, its grade, and the users grade point average
Self-note: Class needs to ask what class, ask what grade in that class, get gradepoint average.
If you're like me when I first took java and I started getting advice, though I heard terms like method/constructor/etc, I didn't truly start to understand it until way later.
Does your teacher require you to use more than 1 class for this program and are you using an IDE (Eclipse, netbeans, etc)?
Usually an IDE will give you options to complete a JOptionPane which saves your wrists some fatigue and helps you pick out what you need.
Here's something you may consider starting out with:
public class Grades{
double grade;
double gpa;
String course;
public static void main(String[] args) {
course = JOptionPane.showInputDialog("Please enter the class name");
grade = JOptionPane.showInputDialog("Please enter a grade of 1-100:");
}What that does is declare three variables (grade, gpa, and class).
Then it asks the user for their class name and a number grade from 1-100. (If your teacher isnt asking for anything specific like a letter grade then I would go with that)
It takes the user's input and stores it into grade and gpa as shown to the left of the Joptionpane( ie. grade = )
You'll probably want to make a loop and use a YES_NO_CANCEL Joptionpane (google for usage and ask for more help if you need help writing this)
So that a student can enter as many grades as he wants before stopping the program.
Then you'll have to take all those grades and get the average and assign a letter grade based on what the average is( im not sure exactly how GPA works but it's probably like if you have a grade of 90+ it's 4.0, 80+ is 3.0, etc etc)
Good luck mate. -

2. Write a program for a college��s admission office. Create variables to store a student��s numeric high school grade point average (for example, 3.2) and an admission test score. Print the message ��Accept�� if the student has any of the following:
�h A grade point average of 3.0 or above an admission test score of at least 60
�h A grade point average of below 3.0 and an admission test score of at least 80
If the student doesn��t meet either of the qualification criteria, print ��Reject��.

System.in.read(); System.in.read();
if(GPA > 3.0 && ATS > 60)
System.out.println("Accept");
if(GPA < 3.0 && ATS >= 80)
System.out.println("Accept" );
else
System.out.println("Reject");You'll have to read the values in differently. Read the values that the user enters as Strings, then convert them to a float (or double) and an int for GPA and ATS respectively. That way your compares will work right. The way you have it now to accepted you have to have an ATS higher than the '>' char, and there's no way to have GPA's that aren't ints. Also, if you put '3' in as your GPA, it gets converted to 51 because of they way your converting to chars.
The way to do all this stuff has been covered many times in the forums so finding answers on how to do all I suggested should be easy. Good luck. -

private char getUserChar (char[] canAccept)
// Build up a list of the valid characters as a string, we will use it in 2 places...
StringBuffer buf = new StringBuffer ();
for (int i = 0; i < canAccept.length; i++)
buf.append (canAccept);
if (i < (canAccept.length - 1))
buf.append (", ");
// Build up an error string we use for when the User gets it wrong...
StringBuffer errstr = new StringBuffer ("Input value must be one of: ");
errstr.append (buf);
// Not the best use of while here but not too bad...
while (true)
System.out.println ("Please enter a character [" + buf.toString () + "]");
// Read a character from the User.
char c = (char) System.in.read ();
// Determine whether the character is one of those that we allow...
for (int i = 0; i < canAccept.length; i++)
if (c == canAccept[i])
// It is one, cool...let's return, no more to do here...
return c;
// If we are here then they've got it wrong, output a message.
System.out.println (errstr.toString ());
And then usage would be simple:
char[] grades = {'A', 'B', 'C', 'D', 'E', 'F'};
char c = this.getUserChar (grades);Enjoy...
