建议贴代码时按格式粘贴，方便大家查阅！

public class Main {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        System.out.print("输入成绩: ");
        double grade = input.nextDouble();
        System.out.println("成绩等级: " + printGrade(grade));
    }

    public static String printGrade(double s) {
        if (s >= 90.0) {
            return "A";
        } else if (s >= 80.0) {
            return "B";
        } else if (s >= 70.0) {
            return "C";
        } else if (s >= 60.0) {
            return "D";
        } else {
            return "E";
        }
    }
}
