我似乎无法让我的百分比正确显示。每次循环时总是显示0.0。代码中的其他一切似乎都起作用。无法正确显示百分比
我可能错过了一些明显的东西，但是当谈到Java的时候，我有些不知所措，因此非常感谢大家的帮助。
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();
}
}
