Calculating percentage in Java

In this article, you will learn how to calculate the percentage of a total using the Java programming language. Such a type of logical query can be asked in a programming interview or need to be implemented during some application development. In some cases, when there is a need to find the ratio or portion of a quantity as a part of another quantity, you should communicate it as a percentage. This exercise will basically simplify the essential function that we will use to have the option to calculate a percentage.

Calculate Percentage

A percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100. The formula used to calculate percentage-

Percentage = (value/total value)×100%

Java program to calculate percentage

import java.util.Scanner;
public class CalculatePercentage {
   public static void main(String args[]){
      float percentage;
      float totalmarks;
      float scored;
      
      Scanner sc = new Scanner(System.in);
      System.out.println("Enter your marks : ");
      scored = sc.nextFloat();

      System.out.println("Enter total marks : ");
      totalmarks = sc.nextFloat();

      percentage = (float)((scored / totalmarks) * 100);
      System.out.println("Percentage : "+ percentage);
   }
}

Enter your marks : 375
Enter total marks : 400
Percentage : 93.75
