public class Main {
public static void main(String[] args) {
Result_Card Subject = new Result_Card();
System.out.println(Subject.english(50));
System.out.println(Subject.islamiat(60));
System.out.println(Subject.math(70));
System.out.println("Total: " + Subject.total());
System.out.println("Average: " + Subject.average() + "%");
}

Answer 1

Average méthode must return float value. You Can Do this

double average(){
return ((English + Islamiat + Math)*100.0)/300.0;
}

Or

float average(){
return ((float)(English + Islamiat + Math)*100)/300;
}

Good pratice : attribut must be in camelCase (int english; int islamiat; ...)

Answer 2

There are no error in your program running perfectly just one correction required average method return the float value👍

Answer 3

if input is 60 +70 +70 average is 200/3 = 66.6666666
but your code prints 66.0
because result of dividing two int
a / b
is integer instead of float
(float) a / b

Answer 4

It is giving one error
