# Demystifying the ‘Average Percentage Calculator Program in Java’

Delve into the world of programming with our comprehensive guide on the ‘Average Percentage Calculator Program in Java’. This blog will introduce you to the fundamentals of the program, focusing primarily on how it can be implemented in Java, a popular object-oriented programming language. By the end of this blog, you will have a deeper understanding of how to write, compile, and run an ‘Average Percentage Calculator Program in Java’.

### Average Percentage Calculator Program in Java- Code

```
// Importing the Scanner class to read user input
import java.util.Scanner;

// Creating a class named AveragePercentageCalculator
public class AveragePercentageCalculator {

// Main method
public static void main(String[] args) {

// Creating a Scanner object to read user input
Scanner input = new Scanner(System.in);

// Prompting the user to enter the number of subjects
System.out.print("Enter the number of subjects: ");

// Reading the number of subjects entered by the user
int numSubjects = input.nextInt();

// Initializing a variable to store the total percentage
double totalPercentage = 0;

// Looping through each subject
for (int i = 1; i <= numSubjects; i++) {

// Prompting the user to enter the percentage for each subject
System.out.print("Enter the percentage for subject " + i + ": ");

// Reading the percentage entered by the user
double percentage = input.nextDouble();

// Adding the percentage to the total percentage
totalPercentage += percentage;
}

// Calculating the average percentage
double averagePercentage = totalPercentage / numSubjects;

// Displaying the average percentage to the user
System.out.println("The average percentage is: " + averagePercentage + "%");

// Closing the Scanner object
input.close();
}
}```

#### Output

``````Enter the number of subjects: 3
Enter the percentage for subject 1: 45
Enter the percentage for subject 2: 73
Enter the percentage for subject 3: 54
The average percentage is: 57.333333333333336%``````

## Understanding the ‘Average Percentage Calculator Program in Java’

• The program starts with importing the Scanner class from java.util package.
• The main method is declared where the execution of the program begins.
• A Scanner object is created to take user inputs.
• The number of subjects is asked and stored in variable ‘n’.
• An integer array ‘marks’ is declared to store the marks of ‘n’ subjects.
• Using a for loop, marks for each subject are taken as input and added to the sum.
• The average is then calculated by dividing the sum by ‘n’.
• Finally, the average is printed on the console.
