create a menu in java ?

Question

Hi Design classes that reflect vehicle car american car foreign car truck and bicycle with ALL appropriate inheritances. vehicle is the parent. Your code must override the toString method in each class to display ALL the relevant information from the record. Also design an application with a main that tests your classes and processes a file of records (main is specified later). The file of data to be used from the menu system has the following format: vehicle (fixed) owner's name (string) address (string) phone (string) email (string) car (fixed) owner's name (string) address (string) phone (string) email (string) true or false for convertible (boolean) color (string) american car (fixed) owner's name (string) address (string) phone (string) email (string) true or false for convertible (boolean) color (string) true or false for made in Detroit (boolean) true or false for union shop (boolean) foreign car (fixed) owner's name (string) address (string) phone (string) email (string) true or false for convertible (boolean) color (string) country of manufacturer (string) import duty (float) bicycle (fixed) owner's name (string) address (string) phone (string) email (string) # of speeds (int) truck (fixed) owner's name (string) address (string) phone (string) email (string) # of tons (float) cost of truck (float) date purchased (format below in exmample) etc.....these records can appear in any order and there can be any number of them. Each record will have a line that identifies its type and then on separate lines will be the data. Records will have a blank line between them. You will need to use an array of Vechiles to store the data. Here are some examples of data: foreign car aMarioy Mario's house (777) 777-7777 gmario@mario.com false black Italy 4415.91 truck aDougy Doug's house (123) 456-7890 hdoug@doug.com 30 61234.56 8/10/2003 vehicle aRobby Rob's house (987) 654-3210 irob@rob.com bicycle bTommy Tom's house (246) 810-1214 jtom@tom.com 7 truck bGeorge George's house (666) 666-6666 kgeorge@george.com 25 51234.56 12/4/2004 vehicle bTim Tim's house (111) 111-1111 tim@tim.com bicycle bJim Jim's house (555) 555-5555 Ajim@jim.com 5 american car bJohn John's house (888) 888-8888 Bjohn@john.com true green false true car cKen Ken's house (999) 999-9999 Cken@ken.com false orange foreign car cMario Mario's house (777) 777-7777 Dmario@mario.com false black Italy 4415.91 truck zDoug Doug's house (123) 456-7890 Edoug@doug.com 30 61234.56 8/10/2003 vehicle eRob Rob's house (987) 654-3210 Frob@rob.com bicycle fTom Tom's house (246) 810-1214 Gtom@tom.com 7 american car gSam Sam's house (333) 333-3333 Hsam@sam.com false blue true false Write an application with a main that reads a file (from the command line) and fills an array of type vehicle[] with new vehicle (params) new car (params) new american car (params) new foreign car(params)  new truck (params) new bicycle (params) etc. depending on the first line that identifies each record. Then it has a menu system that has the following features (THE MENU ITEMS SHOULD BE ABLE TO BE CHOSEN IN ANY ORDER AND CONTINUOUSLY UNTIL THE USER ENTERS THE WORD STOP): 1. Calls a printAll method that can be passed an array of type vehicle[] and which prints each element of the array using the appropriate toString() methods. ArrayList is fine if you wish to use it. 2. Calls a sort method that can be passed an array of type vehicle[] and which sorts the array by email addresses and prints the new sorted array using appropriate toString() methods. Any sort method is fine but it should sort according to unicode (case sensitive that is to say that all upper case is before any lower case)! 3. Calls a method that prints the number of records. 4. Calls a method that prints just the bicycles and trucks (from the sorted array using the appropriate toString() methods). 5. Calls a method that prints the vehicles in area code 987. Be sure to declare variables as private to extend all the classes appropriately and to have the right constructors (using super where appropriate) and the getters and setters for ALL the variables. MUST SEND ALL THE OUTPUT FROM PRINTING TO THE CONSOLE NOT TO A WINDOW. MUST TAKE ALL THE OPTIONS FOR THE MENU FROM THE CONSOLE.

Try this: // Vehicle.java class Vehicle { private String ownerName; private String address; private String phone; private String email; public Vehicle(String ownerName String address String phone String email) { this.ownerName = ownerName; this.address= address; this.phone = phone; this.email = email; } public String getOwnerName() { return ownerName; } public void setOwnerName(String ownerName) { this.ownerName = ownerName; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } public String getPhone() { return phone; } public void setPhone(String phone) { this.phone = phone; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public String toString() { return Owner's name :  + ownerName +
