Explanation / Answer

import java.util.Scanner;

public class TheaterSeatingChart {
   static int[][] priceSeatingChart = {
           { 10, 10, 10, 10, 10, 10, 10, 10, 10, 10 },
           { 10, 10, 10, 10, 10, 10, 10, 10, 10, 10 },
           { 10, 10, 10, 10, 10, 10, 10, 10, 10, 10 },
           { 10, 10, 20, 20, 20, 20, 20, 20, 10, 10 },
           { 10, 10, 20, 20, 20, 20, 20, 20, 10, 10 },
           { 10, 10, 20, 20, 20, 20, 20, 20, 10, 10 },
           { 20, 20, 30, 30, 40, 40, 30, 30, 20, 20 },
           { 20, 20, 30, 40, 50, 50, 40, 30, 20, 20 },
           { 30, 40, 50, 50, 50, 50, 50, 50, 40, 30 } };

   /**
   * @param args
   */
   public static void main(String[] args) {

       int selectPrice = getPrice();
       printConfirmation(checkAvailability(selectPrice));

   }

   /**
   * @param flag
   */
   public static void printConfirmation(boolean flag) {
       if (flag) {
           System.out.println("Your Seat is confirmed! Enjoy your movie");
       } else {
           System.out
                   .println("A Seat at this price is not available. Good Bye");
       }
   }

   /**
   * @return
   */
   public static int getPrice() {
       Scanner scanner = new Scanner(System.in);

       System.out.print("Please pick a price: ");
       int selectPrice = scanner.nextInt();
       return selectPrice;
   }

   /**
   * @param selectPrice
   * @return
   */
   public static boolean checkAvailability(int selectPrice) {
       System.out.println("Checking for the Availability... ...");
       for (int i = 0; i < priceSeatingChart.length; i++) {
           for (int j = 0; j < priceSeatingChart[i].length; j++) {
               if (priceSeatingChart[i][j] == selectPrice) {
                   priceSeatingChart[i][j] = 0;
                   return true;
               }
           }

       }
       return false;
