public class T {
public static void main(String[] args) {
int price = 5000;
Scanner s = new Scanner(System.in);
System.out.print("输入订票月份:");
int month = s.nextInt();
if (month 0 month 13) {
if (month 3 month 11) {
System.out.println("该月车票价格如下:头等舱" + price * 0.9 + "元" + " " + "经济舱" + price * 0.8);
} else System.out.println("该月车票价格如下:头等舱" + price * 0.5 + "元" + " " + "经济舱" + price * 0.4);
} else System.out.println("请输入正确的月份");
}
}
在你的基础上稍稍改动：
import java.util.Scanner;
public class JiPiao {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("请输入您要出行的月份：");
int YueFen = input.nextInt();
System.out.println("请问您选择头等舱还是经济舱？头等舱输入1，经济舱输入2");
int XuanZe = input.nextInt();
if (XuanZe == 1 || XuanZe == 2) {
} else {
System.out.println("请输入数字1，2");
}
double JiaGe;
if (YueFen = 10 YueFen = 4) {
if (XuanZe == 1) {
JiaGe = 5000 * 0.9;
System.out.println("机票的价格为：" + JiaGe);
} else if (XuanZe == 2) {
JiaGe = 5000 * 0.8;
System.out.println("机票的价格为：" + JiaGe);
} else {
System.out.println("输入错误");
}
} else if (YueFen = 1 YueFen = 3 || YueFen == 11 || YueFen == 12) {
if (XuanZe == 1) {
JiaGe = 5000 * 0.5;
System.out.println("机票的价格为：" + JiaGe);
} else if (XuanZe == 2) {
JiaGe = 5000 * 0.4;
System.out.println("机票的价格为：" + JiaGe);
} else {
System.out.println("输入错误");
}
}
}
}
public class Ticket {
private int month;
private int classLevel; //1: 头等舱, 2: 经济舱
private int price;
private int basePrice = 5000; //原价
public Ticket(int month, int classLevel) {
this.month = month;
this.classLevel = classLevel;
}
public void showMeThePrice() {
//旺季月份: 4-10
if ((month = 4) (month = 10)) {
if (classLevel == 1) {
price = basePrice * 0.9;
System.out.println("Month: " + month + "; Class: " + classLevel + "; Price: " + price);
} else if (classLevel == 2) {
price = basePrice * 0.8;
System.out.println("Month: " + month + "; Class: " + classLevel + "; Price: " + price);
}
}
// 淡季月份: 1,2,3,11,12
if ((month = 1) (month = 3) || month = 11 || month = 12) {
if (classLevel == 1) {
price = basePrice * 0.5;
System.out.println("Month: " + month + "; Class: " + classLevel + "; Price: " + price);
} else if (classLevel == 2) {
price = basePrice * 0.4;
System.out.println("Month: " + month + "; Class: " + classLevel + "; Price: " + price);
}
}
}
}
测试类：
public class Test {
Ticket myTicket = new Ticket(4, 1); //例如：四月，头等舱
myTicket.showMeThePrice();//输出显示价格
...
}
以上代码全部手打，因为公司没有安装jdk，所以无法测试，你自己调试吧。
尝试解答一下，这个里面还有老年和教师的判断就省略，主要是打折的代码
import java.util.Scanner;
class Test{
public static void main (String[] args){
Scanner sc = new Scanner(System.in);
System.out.println("请输入消费的金额：");
double oldprice = sc.nextDouble();
double newprice;
if(oldprice = 2000){
newprice = oldprice * 0.85;
}else if(oldprice = 1000 oldprice 2000){
newprice = oldprice * 0.9;
}else
newprice = oldprice;
Judge jud = new Judge();
if(jud.isTeacher()|| jud.isOldman())
newprice = newprice * 0.95;
System.out.println("打折后的价格是：" + newprice);
System.out.println("折扣的程度是： " + newprice / oldprice);
}
}
class Judge{
public boolean isTeacher(){
boolean isTeacher = false;
return isTeacher;
}
public boolean isOldman(){
boolean isOld = false;
return isOld;
}
}
