  • What is CGPA?

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.

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 an 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 standard values here.



Sample Program GPA – 2 ( Using Command-Line Arguments )

Here we go another program using command line arguments. 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 ) :

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 a program to calculate the GPA by creating a new separate class for ( CGPAcalculation) and taking inputs using  scanner class method with sample outputs.
