【我的Java课-1】if 与 else 语句

根据分数判断成绩:

package com.kangyee.zuoye;public class zuoye {public static void main(String[] args){int Score = 100;if (Score >= 90 && Score <= 100){System.out.println("优秀");}else if(Score >= 80 && Score <= 89){System.out.println("优良");}else if(Score >= 70 && Score <= 79){System.out.println("中等");}else if(Score >= 60 && Score <= 69){System.out.println("及格");}else if(Score >= 0 && Score <= 59){System.out.println("不及格");}}}

以上写法并非最优,能按最优的方法写是最好的
