Calculate Percentage in Java

Percent means percent (hundreds), i.e., a ratio of the parts out of 100. The symbol of a percent is %. We generally count the percentage of marks obtained, return on investment etc. The percentage can go beyond 100% also.

For Example, assuming that we have total and a part. So we say what part is what percent of total and should be calculated as −

percentage = ( part / total ) × 100

Algorithm

Below is the algorithm to calculate percentage in Java:

1. Collect values for part and total
2. Apply formula { percentage = ( part / total ) × 100 }
3. Display percentage

Example

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

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

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

Output

Enter your marks ::
500
Enter total marks ::
600
Percentage ::83.33333
