Java programming (arrays and loops)
<p>Basic Programming Concepts 
Lab # 9 – Arrays
Write a cinema reservation program to allow customer to reserve cinema seating. At the beginning of the program, ask the customer to input the name and display customize greeting message. Once the seat is reserved, it should be marked as ‘**’. If customer chooses a seat that has been reserved by other customer, display a message to inform customer and suggest the next available seat. 
Sample output:</p>

<p>Hi, what is your name?
Amy</p>

<p>Welcome, Amy!</p>

<p>00  01  02  03  04<br>
05  06  07  08  09<br>

20  21  22  23  24<br>
25  26  27  28  29<br>
Which seat do you want?
21</p>

<p>Would you like to make another booking?(Y or N)</p>

<p>If seat chosen has been reserved by others, advice next available seat.</p>

<p>Now for the code. The problem with the code is because I probably don't know how to change someone's "y" into a "true" for boolean. Why can't coding ever be easy?</p>

<pre><code>import java.util.*;

public class cinema
{

public static void main(String args[])
{
    Scanner input = new Scanner(System.in);

    int booking;
    String name;
    int suggestion = 0;
    boolean check1 = true;
    String check2 = "_";
    String check11 = "_";

    //create array
    final int ARRAY_LENGTH = 30;
    int[] array = new int[ARRAY_LENGTH];

    String[] seats = { "00", "01" , "02" , "03" , "04" , "05" , "06" , "07" , "08" , "09" , "10"

                          , "22" , "23" , "24" , "25" , "26" , "27" , "28" , "29"};

    System.out.println("Hi, what is your name?");
    name = input.nextLine();

    System.out.printf("Welcome,%s!\n",name);

    for(int a = 0; a &lt; 30; a++ ){
    System.out.printf("%s\t", seats[a]);
    if (a % 5 == 4){
    System.out.printf("\n");
    }
    }
    System.out.println("Which seat do you want?");
    booking = input.nextInt();

    if(seats[booking] == "**"){
        System.out.println("Sorry! Seat taken.");
        for(int b = 0; b &lt; 30; b++){
            if(seats[booking + b] == "**"){
                check2 = seats[booking + b];
            }
            else if(seats[booking - b] == "**"){
                check2 = seats[booking - b];
            }
            else{
            }
        }//end for loop
        System.out.printf("Suggest to take seat:%s\n", check2);
    }//end if

    seats[booking] = "**";

    System.out.println("Would you like to make another booking?(Y or N)");
    check11 = input.nextLine();

    while(check11 == "y"||check11 == "n"){
    if(check11 == "y"){
        check1 = true;
        System.out.print("a");
    }
    else if(check11 == "n"){
        check1 = false;
        System.out.print("b");
    }
    else{
    System.out.println("Would you like to make another booking?(Y or N)");
    check11 = input.nextLine();

    }while(check1);//outer while

<p>Please don't flag it as a duplicate. The problem in it is different.
I can't get the </p>

<p>"Would you like to make another booking?(Y or N)"</p>

<p>to work. When I meant I couldn't get it to work, I meant that the program wouldn't let me have the opportunity to enter y or n. The true problem is the check11 = input.nextLine();. Anyone can tell me what's wrong with it?</p>

<p>Also, the previous reference really didn't help. I didn't understand how it refers to my quetion.</p>
