Java-采用并列式多分支结构评价等级

编写程序

public class task03_1 {
    public static void main(String[] args) {
        int score;
        String level;
        Scanner sc = new Scanner(System.in);

        System.out.print("score = ");
        score = sc.nextInt();

        level = " ";
        if(score > 100) level = "超出范围";
        if(score >= 90 && score <= 100) level = "优秀";
        if(score >= 80 && score < 90) level = "良好";
        if(score >= 70 && score < 80) level = "中等";
        if(score >= 60 && score < 70) level = "及格";
        if(score >= 0 && score < 60) level = "不及格";
        if(score < 0 ) level = "超出范围";

        System.out.println(level);

    }
}
