Practice Set

1. Write a program to create a class Voter which contains attributes name, date_of_birth and voter_id and voter has a Voter_Card. Provide appropriate constructor to initialize all the attributes of the Voter but voter id must be assigned automatically only when the age of the voter is greater than or equal to 18 years.
VoterCard is a nested class with attributes voter_id and Voter_name. Make sure that voter card is created only when user is a valid voter and if it is already created then must not be assigned the new voter id.

2. Write a program to define two interfaces UGC and AICTE both having a default method
int getAdmission() to take the admission and an abstract method String payFee().

getAdmission() in UGC must ask the percentage in qualifying exam and if the percentage >= 60 then generate the registration number and return.
getAdmission() is AICTE must ask the user to join the counseling after 5 days and display
the date of counseling and return the counseling token number.

Create a class University which inherits both UGC and AICTE and overrides the getAdmission() method only such that it will ask the percentage and if direct admission through UGC is possible then proceed otherwise proceed through AICTE.

University must have attribute fee_due and it should be assigned the due amount accordingly.(E.g fee through UGC is 25000 & fee through AICTE is 34000)

Create a class LPU which inherits University and overrides all the methods. Ask the user to deposit the fee and display the fee due. After depositing the fee display the remaining due fee and return the receipt number.

3. Write a program to create a class named IPL _Team with appropriate attributes for team name, wicketkeeper, allrounder and captain. Provide a constructor to initialize all the attributes.
Player is a private nested class with attributes player name, price and a suitable constructor to initialize the attributes.

In main class, create at least 3 teams each having a captain and a wicket-keeper and at least one all-rounder and store the teams in an arraylist.
Implement a method which displays the name of the team and details of all the players of that
team whose captain is having highest price.

4. Create a class Laptop with attributes model_number, price and RAM.
In main class prompt the user to filter on the basis of model, price or RAM and if user selects Price then display all the laptops in descending order of the price and if user selects RAM then display all the laptops in ascending order of their RAM and if user select model then ask to enter the keyword for model and display all the laptops which contain that keyword in model_number.
