Picking 4 Cards

Write a program that picks four cards from a deck of 52 cards and compute their sum. An Ace, King, Queen, Jack represent 1,13,12,11, respectively. Your program needs to ask the user for the sum, find the number of the total combinations, the number of the combinations that yields the sum, and the list of all the combinations that yields the sum.

// Main method, do not add anything

Scanner kb = new Scanner(System.in);

sum(kb);

}

// Initialize the deck then loop while

// the user wants to continue:

// ask for a sum using the validation method

// loop through every possible selection of 4 cards

// if the sum of the 4 chosen equals the sum desired then update

your counter and output combination

// update the counter for the total number of combinations

public static void sum(Scanner kb)

{

// Initialize Variables (including deck of cards)

// Loop while player wishes to continue

// Use the validation method to prompt for the sum

// Loop through possible combinations (Hint: Use 4 nested for

loops)

// If sum matches then update the counter and output

combination

// Update total combination counter

// Output final results and prompt to continue

// If they do not want to continue the set the boolean variable

for continuing to false

}

// Prompt the user to input the sum of combinations desired. Use the

hasNextInt() method

// to ensure that they are entering a number. Also, continue to loop

until they have entered

// a positive number.

public static int dataValidation(Scanner kb)

{

return 0; // remove 0 and put your variable for the valid input

}

// Create and return a 1-dimensional array for all 52 cards. Note that

// you can don this in one line using the "quick" initialization syntax

// for arrays. Also, do not worry about the suits, just add the numbers

to the array.

// This means that an Ace of Hearts is the same as an Ace of Spades,

they are both 1

// so you will have 4 of each number in the array.

public static int[] initialize( )

{

return null; // remove "null" and put your new array variable

instead

}
