Write a complete Java method that returns an integer. The method declares a Scanner object, then prompts the user for a series o

f integers in a while loop. If the user enters an integer (not a string, double, etc) then read each value entered and keep a running total (a sum). Make sure to validate that the user enters only integers. Include a sentinel value (-1) to allow the user to indicate when they are done. The method returns the total.

Answer:

Here is code in java.

import java.util.*;

class Main

{

 // main method of the class

public static void main (String[] args) throws java.lang.Exception

{

   try{

        // print the running total of all inputs

       System.out.println("total of all the inputs is: "+fun());

       

   }catch(Exception ex){

       return;}

}

/* function to take input from user until input is -1

 and keep a running total */

public static int fun()

{

    int in;

     //scanner class object to read the input

    Scanner scr=new Scanner(System.in);

     // variable to keep running total

    int total=0;

    System.out.println("please enter an Integer:(-1 to stop)");

     // read the input first time

    in=scr.nextInt();

    while(in!=-1)

    {

     // this loop keep taking input until input is -1.

     // calculate running total of all inputs

        total=total+in;

        System.out.println("please enter an number:(-1 to stop)::");

        in=scr.nextInt();

       

    }

     // return total of all inputs

    return total;

   

}

}

Explanation:

Create an object of scanner class in the method fun_tot(),it will take input from user.In while loop it will ask user to give input and calculate the sum of all inputs.when user enter -1 then while loop breaks and the method will return the total of all inputs given by the user.

Output:

please enter an number:(-1 to stop)::23

please enter an number:(-1 to stop)::3

please enter an number:(-1 to stop)::5

please enter an number:(-1 to stop)::76

please enter an number:(-1 to stop)::12

please enter an number:(-1 to stop)::-1

total of all the inputs is: 119

Maurinko [17]

Answer:

Explanation:

The 1980 Toyota Celica is a great car, it was my first car and I loved it. It has many luxury features that you don't see much in cars of that year. It is also extremely reliable and can take lots of use before beginning to give problems. I used to use it to get to and from school on a daily basis and it never once left me stranded. It includes power steering, cruise control, AC, etc. Not much more you can ask for in a car, it is also a very beautiful looking car, especially a well taken care of one. Enjoy your car.

"write a program to play and score the paper-rock-scissor game. each of two users types in either p, r, or s. the program then a
algol13

The program is an illustration of conditional statements.

Conditional statements are used to execute instructions, if and only if certain <em>condition or conditions </em>are met.

Take for instance: <em>If b = 5, print "ab"</em>

The above print statement will only be executed, if the <em>value of b is 5</em>

The paper-rock-scissor program in Python where comments are used to explain each line is as follows,  

#This imports the random module

import random

#This is used to control the repetition of the game

playagain ="T"

#The following is repeated until the user chooses not to play again

while(playagain == "T"):

   #This generates a random choice for the computer

   computer = random.choice(['Rock', 'Paper', 'Scissors'])

   #This gets input for the player

   player = input('Choose: ')

   #If the player and computer choose the selection

   if player == computer:

       #Then, it's a tie

       print('A tie - Both players chose '+player)

   #If the player wins

   elif (player.lower() == "Rock".lower() and computer.lower() == "Scissors".lower()) or (player.lower() == "Paper".lower() and computer.lower() == "Rock".lower()) or (player == "Scissors" and computer.lower() == "Paper".lower()):

       #This prints "player won" and the reason

       print('Player won! '+player +' beats '+computer)

   #If otherwise,

   else:

       #This prints "computer won" and the reason

       print('Computer won! '+computer+' beats '+player)

   #This asks if the player wants to play again

   playagain = input("Play again? T/F: ")

At the end of each round,

  • The program displays the winner
  • Or prints a tie, if there's a tie

Kamal plans to offer new, more favorable contracts to business customers who are now receiving a discount and use wireless servi
raketka [301]

Solution :

'AND" operation is a logical operation and is used in logical connective combining two statements and in truth tables.

Using AND operation verifies whether the outcome P and Q is true only when both the P as well as Q are true.  If one of the P or Q is not true, then outcome result will be false.

In the context, Kamal wishes to offer a new and more favorable contracts to the business customers who use a wireless services and receive a discount.

Therefore, using the AND operation of the customers as :

Customer     Wireless     Discount     Outcome

   A                   N                   N             FALSE

   B                   Y                   N             FALSE

  C                   N                   Y              FALSE

   D                   Y                   Y             TRUE

Program code below.

def judge(auction,price):

"""

Function: Returns Name who auctioned very near to give price

Input :

auction : list of tuples

price : auction price

output: returns name of best auction amount holder

"""

diff = [] #storing differences between auctionist amount and price

count = 0

for each_pair in auction:

if each_pair[1]<=price:

diff.append(price-each_pair[1])

else:

count+=1

diff.append(each_pair[1])

if count == len(auction): #check for if no one have auctioned good amount

return None

else:

more_possibility_index = diff.index(min(diff)) #finding index of best amount from diff list

return auction[more_possibility_index][0]

auction = [('Alice',430),('Bob',538),('Carol',487),('David',550)]

price = 520

print(judge(auction,price))

I kept the output at the attachment.
