前言
条件判断的语法:if()…else if()…else
一、具体实现
import java.util.Scanner;
public class Day02_1 {
public static void main(String[] args) {
// TODO Auto-generated method stub
//创建scanner scoreInput对象
Scanner scoreInput = new Scanner(System.in);
//输入提示
System.out.println("请输入你的成绩");
//调用scoreInput方法,定义score接收用户输入值
int score = scoreInput.nextInt();
String result = new String("结果");
//判断分数等级
if(score >= 90) {
result = new String("你优秀了");
}else if(score >= 80) {
result = new String("你是良");
}else if(score >= 60) {
result = new String("你及格了");
}else if(score < 60) {
result = new String("你不及格,你完了");
}else {
//输入错误
result = new String("这输入什么呀这是!");
}
System.out.println(result);
}
}
