JAVA 采用延拓式多分支结构评级

public class task03_5{
    public static void main(String[] args) {
        // 声明部分
        int score;
        String level;
        Scanner sc = new Scanner(System.in);

        // 输入部分
        System.out.print("score = ");
        score = sc.nextInt();

        // 处理部分
        level = "";
        if (score > 100) {
            level = "超出范围";
        } else if (score >= 90) {
            level = "优秀";
        } else if (score >= 80) {
            level = "良好";
        } else if (score >= 70) {
            level = "中等";
        } else if (score >= 60) {
            level = "及格";
        } else if (score >= 0) {
            level = "不及格";
        } else {
            level = "超出范围";
        }

        // 输出部分
        System.out.println(level);
    }
}
