Contoh program Java untuk mengira jumlah skor dan peratusan

percentage_of_marks = (obtained_marks/total_marks) × 100

// Java Program to demonstrate how is Total marks and Percentages calculated
import java.io.*;
public class TotalMarks_Percent1 {
	public static void main(String[] args){
		int n = 8, t_marks = 0;
		float percent;
		// creation of 1-D array to store marks
		int marks[] = { 69, 88, 77, 89, 98, 100, 57, 78 };
		// calculation of total marks
		for (int j = 0; j < n; j++) {
			t_marks += marks[j];
		}
		System.out.println("Total Marks is: " + t_marks);
		// calculate the percentage
		percent = (t_marks / (float)n);
		System.out.println("Total Percentage is: " + percent + "%");
	}
}

Total Marks is: 656
Total Percentage is: 82.0%

// Java program to compute the total marks and percentage of five subjects taken as input from the user
import java.util.Scanner;

public static void main(String args[]){
    float FLAT, COA, Networking, Python, AI; 
    double t_marks, percent;
    Scanner mk =new Scanner(System.in);
    // Take marks as input of 5 subjects from the user 
    System.out.println("Input the marks of five subjects \n");
    System.out.print("Enter marks of FLAT:");
    FLAT = mk.nextFloat();
    System.out.print("Enter marks of COA:");

    AI = mk.nextFloat();
    // Calculation of total marks and percentage obtained in 5 subjects
    t_marks = FLAT + COA + Networking + Python + AI;
    percent = (t_marks / 500.0) * 100;
    // display the results 
    System.out.println("Total marks obtained in 5 different subjects ="+t_marks);    
    System.out.println("Percentage obtained in these 5 subjects = "+percent);
   }
}

Input the marks of five subjects 

Enter marks of FLAT:98
Enter marks of COA:56
Enter marks of Networking:67
Enter marks of Python:89
Enter marks of AI:78
Total marks obtained in 5 different subjects =388.0
Percentage obtained in these 5 subjects = 77.60000000000001
