- Really need some help with this methodPlease use other methodWrite a static method userPasswordMatch(): Takes 2 String (s1, s2) input Define a boolean variable which you will return at the end of the method Check if String s1 and s2 satisfy username and password pair using “if” and “if else” Return the boolean variable as true Main Method: Set a counter to keep track how many times this program can get input from user In a loop, ask user for input: username and password Check these inputs using userPasswordMatch() method Check If userPasswordMatch() returns false then print: Username or password incorrect. And check if the value of the counter is less than 3, if that is, then print: Try again If the value of the counter is greater than 3, then print: too many attempts Otherwise, print: Login successful
- A method is implemented to compute a formula that involves dividing a quantity by a variable y. If y is 0, then an ArithmeticException will be thrown. How should you handle this situation? Here are some alternatives: 1. Ignore the problem and let your method throw an ArithmeticException. 2.Test for y==0 before doing the computation and, if found, print an error message and return 0. 3.Surround the computation with a try/catch block and print an error message in the catch block before returning 0. a. Compare these three alternatives. That means talk about how each is the same as or different than the other two. b. Is there a fourth alternative that is better than these three? If there is, give it along with a justification. If there is not, explain why not.Q3/ Answer with true or false for any three of the following, ( enhance your answer with interpretation). 1: The EraseMode method is better than the Movie method. 2: The ode45function represents the Euler's method. 3: The instruction Rand(n,0) gives random number between 0 and n. 4: In the Movie method there is no need for a pause.How to implement this method
- Java problem. While out on a standard run we notice that our radar is picking up someone following us. In the hopes of losing them, we look for a nearby debris field to hide in. We notice one not too far away, but we need to make sure that we can get to the middle of the debris field to be properly hidden. Our radar shows the debris field in 2D, so we can visually check if we can make it to the center, but that takes too long. We want a program that will let us know if there is a path from the outside of the debris field to the center. In order to solve this problem, we must think recursively. Create a recursive algorithm that determines if a path exists from the outside of the debris field to the center. The debris field is always square (n by n) and n will always be greater than 1, and always odd. You can enter the debris field from any of the outside spaces, and you simply need to return true if a path exists, and false if a path does not exist. For movement you can only go up,…Java Script There is a single operator in JavaScript, capable of providing the remainder of a division operation. Two numbers are passed as parameters. The first parameter divided by the second parameter will have a remainder, possibly zero. Return that value. Examples remainder(1, 3) → 1 remainder(3, 4) → 3 remainder(-9, 45) → -9 remainder(5, 5) → 0 Notes The tests only use positive and negative integers. Don't forget to return the result.Please look at attached photos. It needs to pass all of the simulations. Thanks in advance Cryptography is the practice of encryption. Information Security uses cryptography techniques to encrypt and decrypt data. A simple encryption method might take plaintext and mix up the letters using some predetermined pattern and then use that pattern to decrypt the data for reading. Ciphers are the algorithms used to put the data into its secret pattern and then systematically decrypt it for reading. This script is going to use a famous simple cipher called the Caesar Cipher. It is a substitution cipher where each letter in the text is 'shifted' in a certain number of places. It uses the alphabet as the primary pattern and then based on the shift number, it would shift all the letters and replace the alphabet with our pattern. For example, if our shift number was 3, then A would be replaced with D, if we performed a right shift. As an example: Text = "THE CAT IS VISIBLE AT MIDNIGHT" Ciphertext…
- Context: I made a program that allowed the user to play TOWERS OF HANOI. user can perid the amount of discs to play and do the movements. HANOI game: It consists of a game of 3 towers and discs. The objective is to pass the disks from a source tower to a destination tower. The problem I have is that the game always starts in Tower 1. I would like you to help me modify the method I have to START THE GAME: When I run it, it always starts in tower 1. I would like the method to start in the tower that the user says. also that he says which tower he wants to finish. Example: I want the game to start in tower 2 and end in tower 1 and validate that the game is over. I HAVE ALL THE GAME MADE. the problem lies in what has been said above. METHOD TO MODIFY SO that the user requests (ORIGIN Tower, DESTINATION Tower and validate if I win the game.) /// public static void Start_hanoi(){ // REQUEST NUMBER OF DISCS System.out.println("Write the number of disks to process: ");ndisk =…In this part you will handle a new kind of transaction called a transfer where money is moved from one account to another account. Implement the method: • public boolean transferFromOneToAnother(String fromName, String toName, double amount) - Make a transfer from one account (fromName) to another (toName). Return true if funds are sufficient for transfer (otherwise false ). (Hint: this is similar to the two methods from Part 2, but you need to think a bit about the success/failure cases.) In the input file, transfers are indicated by listing two account handles and an amount, like lines 2, 4 and 6 of the file input6.txt where funds are transferred from Alice to Bob and vice versa: DEPOSIT Alice 300 Alice Bob 150 DEPOSIT Alice 400 Alice Bob 250 WITHDRAW Bob 200 Bob Alice 600 The result of running it should look like this: % javac-introcs TigerCoin.java % java-introcs TigerCoin Alice : 300.0 (success: true) Alice -> Bob : 150.0 (success: true) DEPOSIT -> Alice : 400.0 (success: true)…Implement the one-time pad encryption scheme in Microsoft Excel. Your worksheet should look as follows: For Encryption: - Have the message occupy adjacent cells in one row, with one bit of the message in each cell. Align the key (the one-time pad) with the message in the next row. Note that the key should be of the same length as the message. In the next row, enter a formula that computes the ciphertext. Decryption is similar: - Have the ciphertext occupy adjacent cells in one row, with one bit of the ciphertext in each cell. Align the key (the one-time pad) with the ciphertxt in the next row. Note that the key should be of the same length as the ciphertext. In the next row, enter a formula that computes the plaintext (message). .
