tell me if my codes is correctly done in calculating the gpa and the quality points and calling the methods for the gpa and quality points because my output is reading zero.
i have also to write two arrays to store both the students grades and course. have no idea on how to start yet and I have to hand this in midnight. here is my codes
public static double calGpa(double totqpts, double totcred)
{
double gpa,totqpt = 0 ;
double grdenum = 0;
int totcreds = 0;
totqpts = totcreds * grdenum;
gpa = totqpts / totcreds;
return gpa;
}
public static double calQualityPoints(double gvp, double qpt)
{
double gvlp, qpts = 0;
double grdeval,totalcred;
if("grde".equals("A"))
{
grdeval = 4 * 3;
}
else if ("grde".equals("B+"))
{
grdeval = 3.5 * 3;
}
else if("grde".equals("B"))
{
grdeval = 3.0 * 3;
}
else if("grde".equals("C+"))
{
grdeval = 2.5 *3;
}
else if("grde".equals("C"))
{
grdeval = 2 * 3;
}
else if("grde".equals("D+"))
{
grdeval = 1.5;
}
else if("grde".equals("D"))
{
grdeval = 1*3;
}
else if("grde".equals("F"))
{
System.out.println("you are on academic probation");
}
return qpts;
}
public static void main(String[] args) {

here is the output.

BUILD SUCCESSFUL (total time: 39 seconds)
need an answer as soon as possible. this have to be hand in by midnight. the quick the answer so that i can work on it.
