我似乎無法讓我的百分比正確顯示。每次循環時總是顯示0.0。代碼中的其他一切似乎都起作用。無法正確顯示百分比
我可能錯過了一些明顯的東西，但是當談到Java的時候，我有些不知所措，因此非常感謝大家的幫助。
package e2E3;
import java.util.Scanner;
public class Main {
public static void calculatePercentage(int studentMark, int maxMark){
double percentage;
percentage = studentMark/maxMark * 100;
System.out.println("%" + percentage);
}
public static void totalAndAverageMark(){
Scanner userInput = new Scanner(System.in);
int numberOfStudents = 0;
int maxMark = 0;
int totalMark = 0;
int studentCount = 0;
int studentMark = 0;
int average = 0;
System.out.println("how many Students Sat the Test?");
numberOfStudents = userInput.nextInt();
System.out.println("what is the Maximum score?");
maxMark = userInput.nextInt();
do {
System.out.println("enter students score..");
studentMark = userInput.nextInt();
calculatePercentage(studentMark, maxMark);
totalMark = totalMark + studentMark;
studentCount = studentCount + 1;
} while (studentCount != numberOfStudents);
average = totalMark/numberOfStudents;
System.out.println("The Average Grade of Students was.. " + average);
}
public static void main(String[] args) {
totalAndAverageMark();
}
}
