Java serialization 69- accept input, with an array of analog Stack

First, write a hotel management system

1. Direct code on

Package com.bjpowernode.java_learning; 


public  class D69_1_ { 

  // write a program to simulate the hotel management system: booking, check-out ....... 

  public  static  void main (String [] args) { 

   

  } 

} 

class Room { 

  String NO; 

  String of the type; // "standard", "Double", "Deluxe" 

  boolean isUse; // to true representation occupation, false representation idle 

} 

class hotel { 

  // provisions hotel: five, ten rooms on each floor , standard layer 2, 3, 4 Double layer 5 Deluxe 

  Room [] [] rooms; 

  // no parameter 

  Hotel () { 

    the this (5,10 ); 

  } 

  Hotel ( introws, int cols) { 

    Rooms = new new Room [rows] [cols]; 

    / * 

     * Rooms [0] [0] .... 

     * Rooms [. 4] [. 9] .... 

     * / 

   

  } 

  // provide external method predetermined 

}

Second, the user accepts keyboard input

1. The following demonstrates how to accept user input

 

Package com.bjpowernode.java_learning; 


Import java.util.Scanner; 


public  class D69_2_AcceptUserInput { 

  public  static  void main (String [] args) { 

    Scanner S = new new Scanner (the System.in); 

    // program runs to here, stop and wait for user input 

    String userInput = s.next (); 

    System.out.println ( "You entered:" + userInput); 

  } 

}

Third, the use of analog array stack Stack

package com.bjpowernode.java_learning;



public class D69_3_ArraysSimulateStack {

  public static void main(String[] args) {

    Stack s = new Stack(2);

    User69 u1 = new User69("jfidsa",12);

    User69 u2 = new User69("jfiddfsa",12);

    User69 u3 = new User69("jfidfdsfsa",12);

    try {

      s.push(u1);

      s.push(u2);

      s.push(u3);

    }catch(StackOperationException E) { 

      System.out.println (E); 

    } 

//       System.out.println (s.pop ()); 

  } 
} 



class Stack { 

  // use arrays to store data, note stack may store a plurality of reference element type 

  Object [] elements; 

  // points to a frame above the top element 

  int index; 

 

  // stack default initial capacity is 10 

  stack () { 

    the this (10 ); 

  } 

  stack ( int max) { 

    elements = new new Object [max]; 

  } 

  // stacks should provide a method outside of a push 

  public  void Push (Object Element) throws{StackOperationException 

    IF (index == elements.length) { 

      the throw  new new StackOperationException ( "the stack is full" ); 

    } 

    Elements [index ++] = Element; 

  } 

  // External provide a method popped 

  public Object POP () throws {StackOperationException 

    IF (index == 0 ) { 

      the throw  new new StackOperationException ( "stack is empty" ); 

    } 

    return Elements [- index]; 

  } 

} 


class User69 { 

  String name; 

  int Age;

  User69(String name,int age){

    this.name = name;

    this.age = age;

   

  }

  public String toString() {

    return "User是我";

  }

}

class StackOperationException extends Exception{

  public StackOperationException() {}

  public StackOperationException(String msg) {

    super(msg);

  }

 

}
