我正在尝试使用一个菜单系统,可以从我的数组myHotel []中删除一个客户,这是从一个对象构建的.
if(menu.charAt(0) == 'D')deleteCustomer(myHotel[]);
...
public void deleteCustomer(String myHotel[]){
Scanner input = new Scanner(System.in);
System.out.println("Please Enter Room Number to Delete Customer");
roomNum=input.nextInt();
myHotel[roomNum].setName("e");
}
我弄错了,找不到符号？
这是完整的代码
import java.util.*;
public class Main {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int roomNum=0;
Room[] myHotel = new Room[10];
for (int x =0; x<10; x++){
myHotel[x] = new Room();
}
String roomName;
String menu;
do {
System.out.println("Please Select an Option from the Menu:");
System.out.println("Enter V to View all Rooms");
System.out.println("Enter A to Add Customer to Room");
System.out.println("Enter D to Delete Customer from Room");
System.out.println("Enter Q to Quit");
menu=input.next();
//if(menu.charAt(0) == 'V')viewAllRooms();
//if(menu.charAt(0) == 'A')addCustomer();
if(menu.charAt(0) == 'D')deleteCustomer(myHotel[]);
} while (menu.charAt(0) != 'Q');
while (roomNum < 10) {
for (int x = 0; x < 10; x++ )
if (myHotel[x].getName().equals("e"))System.out.println("room " + x + " is empty");
System.out.println("Enter room number (0-9) or 10 to stop:");
roomNum = input.nextInt();
System.out.println("Enter name for room " + roomNum + " :");
roomName = input.next();
myHotel[roomNum].setName(roomName);
for (int x = 0; x < 10; x++) {
//System.out.println("room " + x + " occupied by " + myHotel[x].mainName);
System.out.println("room " + x + " occupied by " + myHotel[x].getName());
}
}
}
public void deleteCustomer(String myHotelRef){
Scanner input = new Scanner(System.in);
System.out.println("Please Enter Room Number to Delete Customer");
int deleteRoom=input.nextInt();
myHotelRef[deleteRoom].setName("e");
}
}
