ICSE JAVA PROGRAMS 2018: SECTION B QUESTION 4

Programming for school students ( upper to middle/secondary school) PYTHON AND JAVA PROGRAMS

Design a Railway Ticket Class with the following description:

Instance Variables/Data Members:

String name                     : To store the name of the customer

String coach                     : To store the type of coach customer wants to travel

long mobno                     : To store customer’s mobile number

int amt                             : To store basic amount of ticket

int totalamt                     : To store the amount to be paid after updating the original amount

Member methods :

void accept () – To take input for name, coach, mobile number and amount.

void update() – To update the amount as per the coach selected

(extra amount to be added in the amount as follows)

Type of Coaches Amount

First_AC                  700

Second_AC              500

Third_AC                 250

sleeper                     None

void display() – To display all details of a customer such as name, coach, total amount and mobile number.

Write a main method to create an object of the class and call the above member

methods.
