我有一个班级作业,要求我们从用户那里获取输入,删除最低的作业成绩,然后再拿几个等级,计算平均成绩。我已经做了所有这些,但最后一步是我们必须询问用户是否要为另一个学生重复该程序。我所拥有的do while
循环不会执行。

public class CalculateGrades{
public static void main(String [] args){
Scanner sc = new Scanner (System.in);
double score;
double sum=0;

do{
//ASSIGNMENT GRADES
for(int i=1;i<=5;i++){
System.out.println("enter grade for assignment " +i);
score=sc.nextDouble();
sum=sum+score;
if(score<lowest){
lowest=score;
}
}
sum=sum-lowest;
double assignmentAvg= sum/4;
System.out.println("After the lowest grade is dropped, your assignment average is " + assignmentAvg);
//EXAM GRADES
System.out.println("enter grade for exam one");
double exam1=sc.nextDouble();
System.out.println("enter grade for exam two");

//LAB GRADE
System.out.println("enter grade for lab");
