if-else条件语句
语法:
if(布尔表达式) {
//如果布尔表达式为true将执行的语句
}
实例一
输入分数,判断段位
public static void main(String[] args){
Scanner sc=new Scanner(System.in);System.out.println("请输入分数");int x = sc.nextInt();if(x >= 0 && x < 60){System.out.println("黑铁");}else if(x >= 60 && x < 70){System.out.println("黄金");}else if(x >= 70 && x < 80){System.out.println("钻石");}else if(x >= 80 && x < 90){System.out.println("星耀");}else if(x >= 90 && x <= 100){System.out.println("最强王者");}else {System.out.println("请重新输入分数");}sc.close();}
实例二
输入年份,判断是平年还是闰年
public class Test {public static void main(String[] args) {Scanner sc=new Scanner(System.in);System.out.println("请输入年份");int year= sc.nextInt();if(year % 4 == 0 && year % 100 != 0 || year % 400 == 0){System.out.println(year + "是闰年");}else{System.out.println(year + "是平年");}sc.close();}
}
