Could someone write the code for this in java? I cannot use java.util random(but i can use scanner). also, i cannot use switch or case.


Program Rock.java contains a skeleton for the game Rock, Paper, Scissors. Add statements to the program as indicated by the comments so that the program asks the user to enter a play, generates a random play for the computer, compares them and announces the winner (and why). For example, one run of your program might look like this:


Enter your play: R, P, or S


r


Computer play is S


Rock crushes scissors, you win!


Note that the user should be able to enter either upper or lower case r, p, and s. Add a loop to make sure the user only enters an R, P, or S. The user's play is stored as a string to make it easy to convert whatever is entered to upper case. Use if statements to convert the randomly generated integer for the computer's play to a string.


public class Rock


{


public static void main(String[] args)


{


String personPlay; //User's play -- "R", "P", or "S"


String computerPlay; //Computer's play -- "R", "P", or "S"


int computerInt; //Randomly generated number used to determine


//computer's play


// Add the code for each action beneath the comment. // more than one line may be needed in some cases // Get player's play -- note that this is stored as a string


// Make player's play uppercase for ease of comparison


// Generate computer's play (0,1,2) – use (int) (Math.random() * 3) to


// generate a random play


// Translate computer's randomly generated play to string // using mutually exclusive conditional statements


// Print computer's play


// See who won. Use nested ifs instead of &&.


}


}


People hardly ever play Rock, Paper, Scissors one game at a time. They play matches that are best 2 out of 3, best 3 out of 5, etc. Change your program to prompt the user for the odd number of games they want to play and use a loop to make sure it is an odd number. Then, add a loop to your program to play the game multiple times. Keep track of who wins, and make sure the loop stops when either the computer or the user has accumulated enough wins. Ties do not count in either the game total or the win totals – so a best 2 out of 3 match requires 3 games to be played where someone wins 2 times.

Program Rock.java contains a skeleton for the game Rock, Paper, Scissors. Open it and save it to your directory.

Add statements to the program as indicated by the comments so that the program asks the user to enter a play,

generates a random play for the computer, compares them and announces the winner (and why). For example, one run

of your program might look like this:

$ java Rock

Enter your play: R, P, or S

r

Computer play is S

Rock crushes scissors, you win!

Note that the user should be able to enter either upper or lower case r, p, and s. The user's play is stored as a

string to make it easy to convert whatever is entered to upper case. Use a switch statement to convert the randomly

generated integer for the computer's play to a string.*/

Given the following code, what logic would you need to include to print all even values stored within the array:

int[] myArray = {1,2,38,4,54,6,7,8,9,10};

for (int i = 0; i < myArray.length; i++) {
//your code goes here
}
NOTE: Your response should be just the missing logic--not the entire problem set.

Write a program that prompts the user to enter the month and year and displays the number of days in the month. For example, if the user entered month 2 and year 2000, the program should display that February 2000 has 29

12.20 LAB: Driving costs - functions

Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f}'.format(your_value))

Ex: If the input is:

20.0
3.1599

the output is:

1.58
7.90
63.20

Your program must define and call the following driving_cost() function. Given input parameters driven_miles, miles_per_gallon, and dollars_per_gallon, the function returns the dollar cost to drive those miles.

Ex: If the function is called with:

50 20.0 3.1599

the function returns:

7.89975

def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon)

Your program should call the function three times to determine the gas cost for 10 miles, 50 miles, and 400 miles.
---------------------------------------------------
I need help for this part
Ex: If the function is called with:

50 20.0 3.1599

how do I get it to input the three to get the output of 7.89975?
-------------------------------------
My code:

# Define your function here.
def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon):
return (driven_miles/miles_per_gallon) * dollars_per_gallon

if __name__ == '__main__':
# Type your code here.

# Miles per gallon from input
miles_per_gallon = float(input())

#Dollars per gallon from input
dollars_per_gallon = float(input())


# Display the results as output

print('{:.2f}'.format(driving_cost(10, miles_per_gallon,dollars_per_gallon)))
print('{:.2f}'.format(driving_cost(50, miles_per_gallon,dollars_per_gallon)))
print('{:.2f}'.format(driving_cost(400, miles_per_gallon,dollars_per_gallon)))

Write a program that prompt the user to enter a bank balance. The balance entered by the user is read into a variable named balance. The program then prompts the user to enter the amount to be deposited. The amount entered by the user is read into a variable named deposit. The program that calculates the new balance, which is the present balance plus the deposit. The program then displays the new balance.
