In this tutorial you will learn about the Java Program to Calculate Average Marks and its application with practical example.
In this tutorial, we will learn to create a Java Program to Calculate Average marks using Java programming.
Prerequisites
Before starting with this tutorial we assume that you are best aware of the following Java programming topics:
- Java Operators.
- Basic Input and Output function in Java.
- Class and Object in Java.
- Basic Java programming.
- If-else statements in Java.
- For loop in Java.
Average
Average can be find by adding the numbers(let say we have 5 number then average is “1+2+3+4+5/5”),and then dividing the total by the total number size (5).
In mathematics, an average is called a “mean” = (sum of values)/number of items.
Java Program to Calculate Average Marks
In our program we will create a program that will Calculate Average of Marks. Firstly we declare required variable and also initiates required values in variable. Next we take values from user at run time and then after we will find the average of Marks.

// java program to find average of marks.. import java.util.Scanner; class AverageMarks { public static void main(String args[]) { // Declaring avriables.. int mark[] = new int[5],i; float sum=0,avg; // Taking values from user... Scanner scan = new Scanner(System.in); System.out.print("Enter marks for 5 Subjects : "); for(i=0; i<5; i++) { mark[i] = scan.nextInt(); // calculating sum sum = sum + mark[i]; } // Finding avergae.. avg= sum/5; /// Printing the result... System.out.print("Average Marks = " +avg); } } |
Output
In the above program, we have first declared and initialized a set variables required in the program.
- mark= it will hold entered numbers.
- sum = it will hold sum of values.
- avg = it will hold average of numbers.
After that we will takes values from user in variable mark[].
And after we will add values taken from user sum=sum+mark[i] and find the average of marks in avg (sum/avg) variable as shown in image below.
And finally we print the result i.e sum of all values and average of given values. The above Program is compile and executed, it will produce the following output:
