Can I have some help debugging this exercise:// Application lists valid shipping codes// then prompts user for a code// Application accepts a shipping code// and determines if it is validimport java. util.*;public class DebugEight1{public static void main(String args[]){Scanner input = new Scanner(System. in);char userCode;String entry, message;boolean found = false;char[] okayCodes = {'A''C''T''H'};StringBuffer prompt = newStringBuffer("Enter shipping code for this delivery\nValid codes are: ");for(int x = 0; x < length; ++x){prompt. append(okayCodes[x]);if(x != (okayCodes. length - 1))prompt. append(", "); }System. out. println(prompt);entry = input. next();userCode = entry. charAt(0);for(int i = 0; i < length; ++i){if(userCode = okayCodes){found = true;}}if(found)message = "Good code";elsemessage = "Sorry code not found";System. out. println(message);}}

Mariah was working on a multimedia presentation that included both video and audio files. the file was huge, and she wanted to send it to her coworker in another office. she needed to reduce the size of the file so that it could be transmitted faster. the utility she used to do this was

This question involves a class named textfile that represents a text file. public class textfile { private string filename; private string filename; private arraylist words; // constructors not shown // postcondition: returns the number of bytes in this file public int filesize() { } // precondition: 0 < = index < words.size() // postcondition: removes numwords words from the words arraylist beginning at // index. public void deletewords(int index, int numwords) { } // precondition: 0 < = index < = words.size() // postcondition: adds elements from newwords array to words arraylist beginning // at index. pub lic voidaddwords(int index, string[] newwords) { } // other methods not shown } complete the filesize() method. the filesize() is computed in bytes. in a text file, each character in each word counts as one byte. in addition, there is a space in between each word in the words arraylist, and each of those spaces also counts as one byte. for example, suppose the words arraylist stores the following words: { mary had a little lamb; its fleece was white as snow. } the filesize() method would compute 4 + 3 + 1 + 6 + 5 + 4 + 6 + 3 + 5 + 2 + 5 as the sum of the lengths of each string in the arraylist. the value returned would be this sum plus 10, because there would also be 10 spaces in between the 11 words. complete the filesize() method below: // postcondition: returns the number of bytes in this file public int filesize() { }

Most information security incidents will occur because of select one: a. users who do not follow secure computing practices and procedures b. increases in hacker skills and capabilities c. poorly designed network protection software d. increasing sophistication of computer viruses and worms
