How to write a java program to calculate CGPA percentage.

How to write a java program to calculate
CGPA percentage. Java code to calculate the
CGPA ( Cumulative Grade Point
Average ), in 5 different ways. Using
standard values, using command line
arguments, inputs through scanner class
and user define method. Cumulative Grade
Point Average ( CGPA ) is overall grade
point average. Definition and sample
programs are described below about GPA.

What is CGPA ?
A: CGPA is overall grade point average. For
each course there are certain credits which
is usually based on how many hours the
class is held in each week.
How to calculate the CGPA and formula ?
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 0.0 to a 4.0. To get
the example student’s GPA , the total grade
points are divided by the total credit hours
attempted. Here is the simple formula to
calculate the GPA ( Grade point average
formula )
Calculate GPA – Java
Program In Five Ways
Program To Find CGPA – 1 ( Using
standard values with outputs )
Here we wrote the code with standard
values. We also embedded a online
execution tool below do check it out.
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.
Java Code using a standard values here.
Output:
Sample Program GPA – 2 ( Using
Command Line Arguments )
Here we go another program using
command line arguments . If you have no
idea bout command line arguments check
out here: Complete guide. In simple
command lines are nothing but giving
inputs on console it itself. Check out the
code and output.
Output ( Using command line
arguments ) :
Calculate GPA Using Arrays
Here we go another method to calculate a
grade point average, taking inputs through
scanner class method.
Output ( Inputs Through Scanner Class ):
Java Program By Using Method
Java code for calculating CGPA using a user
defined method with sample outputs and
execution tool. Check it out!
Output ( User define method ) :
Sample Program – 5 (using class)
Here we go another version of program to
calculate the GPA by creating a new
separate class for ( CGPAcalculation) and
taking inputs using scanner class method
with sample outputs.

}
cgpa = sum/ n;
System. out. println( "cgpa=" + cgp
System. out. println( "percantage

}

Output
