[SOLVED] COMP248 Assignment 4-One Dimensional Array

Description

One Dimensional Array

Write a program that asks a user for names of 8 soccer teams and outputs a possible road map of 4 quarter finals, 2 semifinals, 1 final and the final winner of a tournament.

Your program should proceed as follows:

1. Ask the user for a name for the soccer tournament followed by the names of the 8 participating teams. (You can assume that each name, which can be more than 1 word, will be correctly entered on a separate line.) The participating teams are to be stored in a one-dimensional array.

 

2. Generate the output roadmap by choosing at random combinations of teams and a winner for each combination at each level to produce a final winner. Of course a team can only be in one quarter final game. Figure1 illustrates how teams are matched for the semi-finals and finals.

 

Use the random number generator from the Math class or Random class to randomly pick the original combination of the 8 teams in the quarter finals and the winner of each game.

3. Your program output should be displayed in the format below.

 

4. The user should be able to request for a different outcome until he receives an output that he likes. This involves shuffling the teams in the array to determine who plays against whom in the quarter finals. (You can usenextInt(bound) in a loop to randomize the array- in other words to shuffle the array entries.)

 

5. When a user chooses to stop, your program should display a closing message like:

‘Thank you for using the JAVA Tournament Winner Predictor Program.’

 

Here are a few sample outputs to illustrate the expected behavior of your program.

Question 2 (2-dimensional Arrays)

Write a program that implements a card magic game where you accurately predict a user’s card from a randomly generated 4×4 card matrix.  Your program should proceed as follows:

 

1. Generate a random 4×4 card matrix and print it on the screen.

Tips: You could use a 1D index array for card numbers, 4×4 matrix for cards with one row each for 4 card types. You can randomize rows and columns independently using a loop to swap values at random or use the randomizeArray() method.

 

2. Ask a user to pick a card and to enter the corresponding column number for that card. (You have to make sure that the user enters a number between 1 and 4 and nothing else.)

 

3. Transpose the 4×4 card matrix (i.e. rows matrix becomes column matrix) and print it on the screen. Ask user for the new column number for his chosen card. (Simply swap loop variables.)

 

 

4. Make use of the two inputs from the user to predict his card. Your program output should be displayed in the format below. The user should be able to request for another try until he is satisfied that program correctly predicts the card every single time.

 

5. When a user chooses to stop, your program should display a closing message like:

‘Thank you for using the JAVA Magic 101 Program.’

 

Here is an example of the output to illustrate the expected behavior of your program.

Question 3 (Simple Class Exercise)

Define a class named Car that stores information about a car. It should comprise of the following:

 

1. Private instance variables to store age of the car, its type (sedan or suv) and its cost.
2. 4 constructors:
   1. No argument (sets age to 0, type to sedan and cost to 32000).
   2. one argument constructor (sets cost to a value, age to 0 and type to sedan).
   3. two argument constructor (sets age to a value, cost to a value, and type to sedan).
   4. three argument constructor (sets age to a value, cost to a value, and type to value sedan or suv).

 

3. 3 Accessor methods: – methods to return age, type and cost respectively.
4. 5 Mutator methods: – 3 methods for setting the three values independently, a method to set all three values and a method to set only age and cost of the car.
5. A public method called estimatePrice() that returns the cost of a car based on type and age. A sedan costs $32000, depreciates 10% every year in first five years and 5% every year afterwards. An SUV costs $45000, depreciates 8% every year in the first five years and 4% every year afterwards.
6. A toString() method that returns the type of the car as well as it’s age and
7. An equals() method to test for equality of two objects of class car based on type and age.
8. isLessThan() and isGreaterThan() method to compare between the prices of two objects of class car.

 

1. b) Write a driver class

 

1. Which declares 4 car objects using 4 different constructors and outputs the description of the 4 cars.
2. Test your accessor methods.
3. Calculate the estimated price of the cars given the type and age (include 1 sedan and 1 SUV)
4. Test out all 5 mutator methods to modify car attributes.
5. Test methods toString(), equals() , isLessThan() and isGreaterThan() for different car objects.

 

Here is an example of the output to illustrate the expected behavior of your program.

 

Car C1: This car is type Sedan. Its age is 0 and costs $32000.0 Car C2: This car is type Sedan. Its age is 0 and costs $32000.0 Car C3: This car is type Sedan. Its age is 4 and costs $18000.0 Car C4: This car is type SUV. Its age is 2 and costs $36000.0 Accessor Method: The cartype for car C4 is SUV, its age is 2, and it costs $36000.0 The estimated price of car C3 is $24800.0 The estimated price of car C4 is $39240.0 Mutator Method: The new age for car C3 is 5 Mutator Method: The new cartype for car C3 is SUV Mutator Method: The new cost for car C3 is 14000.0 Mutator Method: The new car age is 9 and its new cost is 9000.0 Mutator Method: The new cartype for car C3 is Sedan, its new age is 14and its cost is 5000.0 toString: This car is type Sedan. Its age is 14 and costs $5000.0 Cars C1 and C2 are equal is true Cars C1 and C4 are equal is false Car C4 is less than C3 is false Car C1 is greater than C3 is true
