Java计算停车费用的应用

计算停车费用。收费标准为：停车收费起始价￥6，停车3小时；超过3小时，按照每小时追加￥3，一天内一次停车收费最多不超过￥36。假定一次停车不超过24小时。编写程序，通过键盘录入停车小时数（整数），然后计算停车费并输出。

 public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        int hours = input.nextInt();
        int fee = 0;
        if (hours <= 3) {
            fee = 6;
        } else if (hours <= 24) {
            fee = 6 + (hours - 3) * 3;
            if (fee > 36) {
                fee = 36;
            }
        }
        System.out.println("停车" + hours + "小时，停车费用为" + fee + "元。");
    }


import java.util.Scanner;

public class CSDNQ7912027 {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("请输入停车小时数：");
        int hours = scanner.nextInt();
        scanner.close();
        double fee;
        if (hours <= 3) {
            fee = 6.0;
        } else if (hours <= 24) {
            fee = 6.0 + Math.min(30.0, (hours - 3) * 3.0);
        } else {
            fee = 36.0;
        }
        System.out.printf("停车费用为：￥%.2f%n", fee);
    }
}
