Answer:
Explanation:
The following code is written in Java and is a method that takes in an ArrayList as a parameter, it then loops through the ArrayList and adds each element to the instance variable called arr as well as a space between each element (this can be removed by deleting the " "). Finally, it prints the final result of the variable arr to the screen.
public static void concatAll(ArrayList<String> myArr) {
String arr = "";
for (int x = 0; x < myArr.size(); x++) {
arr += myArr.get(x) + " ";
}
System.out.println(arr);
}

the following section of psudo code inputs a number n, multiplies together 1 x 2 x 3 x ..... x n, calculates input number/sum and output result of the calculations.
locate 3 errors and suggest a corrected piece of code.
INPUT n
FOR mult = 1 TO n
sum = 0
sum = sum * mult
result = n / sum
NEXT
PRINT result
Answer:
INPUT n
sum = 1
FOR mult = 1 TO n
sum = sum*mult
NEXT
result = n/sum
PRINT result
Explanation:
sum should not be defined inside the for loop because it will reset to the initial number after every loop iteration which is not what is desired. Sum should not be 0 if it is being multiplied then divided. This will cause an error. Result should be calculated after sum has settled on a final number, after the loop has finished.
Your company just installed a new web server within your DMZ. You have been asked to open up the port for secure web browsing on the firewall. Which port should you set as open to allow users to access this new server?
Answer:
The port that should be set open to allow users to access this new server is:
TCP port.
Explanation:
Ports are openings or entrance doors through which data packages have access to a PC or server. TCP and UDP are transport protocols with port numbers. TCP means Transmission Control Protocol. They are used to connect two devices over the internet and other networks. UDP means User Datagram Protocol. They are used to connect applications and to speed the transfer of data. Comparatively, UDP is faster, simpler, and more efficient than TCP. TCP enables retransmission of lost data packets, which UDP cannot do.

im trying to call the keys in a dictionary I have called "planet_dict". in order for them to be included in the for loop, the values of the keys have to be within a range of
273 <= x <= 373
I understand how to do this with certain values, but idk how to call them from a dictionary.
You can do something like this. My code iterates through the dictionary keys and then we use that key to get a value. We check if the value is between 273 and 373 and if it is, it's a water planet. My code is just a general idea of what to do. Instead of printing, you could add the key to a list and then print the contents of the list.

PYTHON HW PLEASE HELP. I NEED THE ACTUAL CODE!!! 100 POINTS AND BRAINLIEST. REPORTING IF YOU DON'T ANSWER
Question 1:
Design a BankAccount Class with the following requirements:
1. Class variables
- Overdraft Fee = 20 (Overdraft fee is subtracted from the account when account balance is negative after a withdraw)
2. Object variables
- Balance (Balance is the amount of money an account has left)
3. Methods
- deposit(amount): Accepts an argument amount of type number, adds this amount to account's balance
- withdraw(amount): Accepts an argument amount of type number, subtract this amount to account's balance, if the resulting balance is negative, apply an Overdraft Fee on the account balance
Test your class to see if it works:
- Scenario 1:
- Create a new account called "college_checking", assign 1000 dollars to the initial balance.
- Withdraw 200 dollars
- Withdraw 500 dollars
- Deposit 100 dollars
- Withdraw 600 dollars
- Check your remaining balance, it should be -220 dollars of balance, because $1000 - $200 - $500 + $100 - $600 - $20(overdraft) = $-220
- Scenario 2:
- Create a new account called "europe_trip_fund", assign 0 dollars to the initial balance.
- Deposit 250 dollars
- Deposit 220 dollars
- Deposit 530 dollars
- Withdraw 721 dollars
- Check your remaining balance, it should be $279 dollars of balance, because $0 + $250 + $220 + $530 - $721 = $279
Question 2:
Design a OverdraftProtectionAccount that inherits from BankAccount Class with the additional requirements:
1. Methods
- withdrawal(amount): Accepts an argument amount of type number, subtract this amount to account's balance, if the resulting balance is negative, log an error message:
"There's insufficient funds in your account to complete this transaction"
to the terminal and stop the transaction so that your balance isn't overdrafted.
Test your OverdraftProtectionAccount class to see if it works:
- Scenario 3:
- Create a new account called "personal_checking", assign 100 dollars to the initial balance.
- Withdraw 20 dollars
- Withdraw 50 dollars
- Deposit 12 dollars
- Withdraw 60 dollars
- Check your remaining balance, it should be 42 dollars of balance, because $100 - $20 - $50 + $12 = $42, the last withdrawal didn't go through because that would leave your account balance negative.
