采用延括式多分支结构评定成绩等级

• 在包里创建Task03_3
  
  import java.util.Scanner;

public class Task03_3 {
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);

}
}
