Program to find out code of grade and percentage calculator in java of a student when the marks of 6 subjects are given.
In this program, we calculate the grade and percentage of students according to 6 subjects marks by the given below methods by if-else loop concepts basic to advance loop in java
best if else if loop example with explanation
The method of assigning grades is –
percentage>=85 grade=A
percentage<85 and percentage>=70 grade=B
percentage<70 and percentage>=55 grade=C
percentage<55 and percentage>=40 grade=D
percentage<40 grade=E
public class Percentagefile {public static void main(String[] args) {
float m1, m2, m3, m4, m5, m6, total, percentage;
char grade = ‘Z’;
Scanner in = new Scanner(System.in);System.out.println(“Please enter marks out 100 of Subject 1”);
m1 = in.nextInt();
System.out.println(“Please enter marks out 100 of Subject 2”);
m2 = in.nextInt();
System.out.println(“Please enter marks out 100 of Subject 3”);
m3 = in.nextInt();
System.out.println(“Please enter marks out 100 of Subject 4”);
m4 = in.nextInt();
System.out.println(“Please enter marks out 100 of Subject 5”);
m5 = in.nextInt();
System.out.println(“Please enter marks out 100 of Subject 6”);
m6 = in.nextInt();
// Total all 6 subject marks
total = m1 + m2 + m3 + m4 + m5 + m6;
// Calculate percentage of All Subject
percentage = total / 6;
if (percentage > 33 && percentage < 100) {
if (percentage >= 100) {
System.out.println(“Your percentage is invaild.”);
} else if (percentage >= 85) {
grade = ‘A’;
} else if (percentage >= 70) {
grade = ‘B’;
} else if (percentage >= 55) {
grade = ‘C’;
} else if (percentage >= 40) {
grade = ‘D’;
} else {
grade = ‘E’;
}
System.out.println(“Your score ” + percentage + “% and your grade is ” + grade + “”);
} else {
System.out.println(“You are Fail or You Enter Invaild Marks”);
}
}
}
Suppose Student S1 finds the following marks:
Subject 1=70, Subject 2 =50, Subject 3 = 80,
Subject 4 = 76, Subject 5 = 56, Subject 6 = 78,
output:
Please enter marks out 100 of Subject 1
70
Please enter marks out 100 of Subject 2
50
Please enter marks out 100 of Subject 3
80
Please enter marks out 100 of Subject 4
76
Please enter marks out 100 of Subject 5
56
Please enter marks out 100 of Subject 6
78
Your score 68.333336% and your grade is C
