Java基础之if语句案例

import java.util.Scanner;
public class  Scanner05
{
public static void main(String[] args)
{

Scanner s = new Scanner(System.in);

System.out.println("从键盘输入小明的期末成绩：");
int Score = s.nextInt();

s.close();

if(Score<0 || Score>100){
System.out.println("您输入的成绩有误，请重新输入");
}else{
if(Score == 100){
System.out.println("奖励一辆BMW");
}else if(Score > 80){
System.out.println("奖励一台8848");
}else if(Score>60){
System.out.println("奖励一本从入门到精通只需33天");
}else{
System.out.println("暴打一顿！！！");
}
}
}
}

演示逻辑运算符中的与操作

需求变更：如果全部及格我就打印全部及格，否则打印有不及格

public class Test01
{
public static void main(String[] args)
{
int chineseScore = 80;
int englishScore = 70;
int mathScore = 99;

if(chineseScore >=60 && englishScore >=60 && mathScore>=60){
System.out.println("全部及格！！！");
}else{
System.out.println("分数不及格！！！");
}
}
}
