PLEASE HELP asap 60 POINTS
needs to be in Java

A programmer has written a method called replaceLetter that counts the amount of times a letter is present in a word. Your job is to modify this existing method to fulfill a new purpose.

Rather than count the instances of a letter in a String, write a program that replaces all instance of one letter with another. You should directly modify replaceLetter to get this program to work. In the starter code, replaceLetter only has two parameter values. Your new version should have a third parameter to indicate which String value is replacing the existing letter.

For example,

replaceLetter("hello", "l", "y")
returns

"heyyo"
Sample output:

Enter your word:
hello

Enter the letter you want to replace:
l

Enter the replacing letter:
x
hexxo
Hint: The letters will be assigned from the user as String values. Make sure to use String methods to compare them!

import java.util.Scanner;

public class JavaApplication45 {

   public static String replaceLetter(String txt, String txt1, String txt2 ){

       char one = txt1.charAt(0);

       char two = txt2.charAt(0);

       String newTxt = "";

       for (int i = 0; i < txt.length(); i++){

           char c = txt.charAt(i);

           if (c == one){

               newTxt += two;

           }

           else{

               newTxt += c;

           }

       }

       return newTxt;

   }

   public static void main(String[] args) {

       Scanner scan = new Scanner(System.in);

       System.out.println("Enter your word:");

       String word = scan.nextLine();

       System.out.println("Enter the letter you want to replace:");

       String txt1 = scan.next();

       System.out.println("Enter the replacing letter:");

       String txt2 = scan.next();

       System.out.println(replaceLetter(word,txt1,txt2));

   }

   

}

Answers

Answer:

I’m sure if I remember that this is “B.”

Explanation:

I have taken computer science class before so I remembered!

The option that is true of functions is B. Functions can help remove repeated code from a program.

It should be noted that the fact that programs are written with functions doesn't mean that they will run quickly.

Functions can help remove repeated code from a program. Also, replacing repeated code with a function doesn't reduce the number of commands the computer needs to run.

Answers

Answer:

The correct option is C) Use a single three-legged firewall with three interfaces

Explanation:

DMZ is an acronym for a demilitarized zone.

A DMZ network is one is situated between the internal network and the Internet. It is supported by an Internet Security and Acceleration (ISA) server.

The interfaces you'd get with the DMZ network are

A public network (Internet Protocol-IP) address  with a public interfaceAn internal network interface with a private network (IP) address  A DMZ interface with a public network (IP) address  

Unlike the back-to-back DMZ settings, a trihomed DMZ is unable to use private IP addresses. To use the trihomed DMZ, public IP addresses are a must suitable requirement.
