import java.util.*;
public class weighted_average
{static Scanner in=new Scanner(System.in);
public static void main(String[] args)
{
String name;
int q1,q2,mt,fexam;
char grade;
double ts;
q1=grades("Quiz1",10);
q2=grades("Quiz 2",10);
mt=grades("Midterm",100);
fexam=grades("Final Exam",100);
ts=fexam*.5+mt*.25+(q1+q2)/20.*100.*.25;
grade=getgrade(ts);
System.out.println(" Grades");
System.out.println("Quiz 1 " + q1);
System.out.println("Quiz 2 " + q2);
System.out.println("Midterm " + mt);
System.out.println("Final Exam " + fexam);
System.out.println("Total Score " + ts);
System.out.println("Final Grade " + grade);
}
public static int grades(String name,int max)
{int grade;
System.out.print("Enter "+name+" grade ");
grade=in.nextInt();
while(grade<0||grade>max)
          {System.out.println("must be between 0 and "+max);
            System.out.print("Enter "+name+" grade ");
            grade=in.nextInt();
}
return grade;
}
public static char getgrade(double g)
{if(g>=90)
      return 'A';
if(g>=80)
      return 'B';
if(g>=70)
