重点再grade.equals上。
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner scan =new Scanner(System.in);
String grade =scan.next();
if(grade.equals("A")){
System.out.println("优秀");
}else if (grade.equals("B")){
System.out.println("良好");
}else if (grade.equals("C")){
System.out.println("及格");
}else if(grade.equals("D")){
System.out.println("不及格");
}else{
System.out.println("未知等级");
}
}
}
