note: You can easily replace a portion of text within a String using the String method "replace()". For example: String svar = "raspberry jam"; svar = svar.replace("jam", "pie"); System.out.println(svar); will print out: raspberry pie A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output.

ALPHABETIC TELEPHONE NUMBER TRANSLATOR Many companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B, and C = 2 D, E, and F = 3 G, H, and I = 4 J, K, and L = 5 M, N, and O = 6 P, Q, R, and S = 7 T, U, and V = 8 W, X, Y, and Z = 9 Create an application that lets the user enter a 10-character telephone number in the format XXX-XXX-XXXX. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. For example, if the user enters 555-GET-FOOD, the application should display 555-438-3663. **the code below gives me an error, can't find where its wrong.** string str = textBox1.Text; const int SIZE = 12; Boolean valid = true; string newStr = ""; if (str.Length != SIZE) {...

Fleet class: Instance Variables An array that stores Aircraft that represents Delta Airlines entire fleet A variable that represents the count for the number of aircraft in the fleet Methods: o Constructor-One constructor that instantiates the array and sets the count to aero readFile()-This method accepts a string that represents the name of the file to be read. It will then read the file. Once the data is read, it should create an aircraft and then pass the vehicle to the addAircraft method. It should not allow any duplication of records. Be sure to handle all exceptions. o writeFile()-This method accepts a string that represents the name of the file to be written to and then writes the contents of the array to a file. This method should call a sort method to sort the amay before writing to it. sortArray()-This method returns a sorted array. The array is sorted by registration number.u addAircraft- This method accepts an aircraft and adds it to the fleet(the array only if it is not...

Counting hashtags Write Python code to count the frequency of hashtags in a twitter feed. Your code assumes a twitter feed variable tweets exists, which is a list of strings containing tweets. Each element of this list is a single tweet, stored as a string. For example, tweets may look like: tweets = ["Happy #IlliniFriday!", "It is a pretty campus, isn't it, #illini?", "Diving into the last weekend of winter break like... #ILLINI #JoinTheFight", "Are you wearing your Orange and Blue today, #Illini Nation?"] Your code should produce a sorted list of tuples stored in hashtag_counts, where each tuple looks like (hashtag, count), hashtag is a string and count is an integer. The list should be sorted by count in descending order, and if there are hashtags with identical counts, these should be sorted alphabetically, in ascending order, by hashtag. From the above example, our unsorted hashtag_counts might look like: [('#illini', 2), ('#jointhefight', 1),...

Scala Programming: Given string str, write a Scala program to create a new string where "Scala " is added to the front of a given string. If the string already begins with "Scala", return the string unchanged. Otherwise, return the string after adding "Scala ". Test the function for two strings "Scala Programming" and "Programming" inside the main method.

JAVA PPROGRAM ASAP Please create this program ASAP BECAUSE IT IS MY LAB ASSIGNMENT so it passes all the test cases. The program must pass the test case when uploaded to Hypergrade. Chapter 9. PC #2. Word Counter (page 608) Write a method that accepts a String object as an argument and returns the number of words it contains. For instance, if the argument is "Four score and seven years ago" the method should return the number 6. Demonstrate the method in a program that asks the user to input a string and then passes it to the method. The number of words in the string should be displayed on the screen. Test Case 1 Please enter a string or type QUIT to exit:\nHello World!ENTERThere are 2 words in that string.\nPlease enter a string or type QUIT to exit:\nI have a dream.ENTERThere are 4 words in that string.\nPlease enter a string or type QUIT to exit:\nJava is great.ENTERThere are 3 words in that string.\nPlease enter a string or type QUIT to exit:\nquitENTER

X609: Magic Date A magic date is one when written in the following format, the month times the date equals the year e.g. 6/10/60. Write code that figures out if a user entered date is a magic date. The dates must be between 1 - 31, inclusive and the months between 1 - 12, inclusive. Let the user know whether they entered a magic date. If the input parameters are not valid, return false. Examples: magicDate(6, 10, 60) -> true magicDate(50, 12, 600) –> false

Lab Goal : This lab was designed to teach you how to use a while loop. Lab Description (JAVA PROGRAMMING): Remove all occurrences of the removal string from the original string. Each time you take out the removal string you must also remove the letter that preceded the removal string. After you remove a string and its leading character, you must check to see if any more occurrences of the removal string exist. Sample Data : xR-MxR-MHelloxR-M R-M sxsssxssxsxssexssxsesss xs fuxqwexqwertyxqwexqwe Sample Output : xR-MxR-MHelloxR-M - String to remove R-M Hello sxsssxssxsxssexssxsesss - String to remove xs sesss fuxqwexqwertyxqwexqwertyrtyxqwertyrtyn - String to remove qwerty fun dogdogcatddodogdogdoggog - String to remove dog catgog algorithm help use indexOf to look for more removals while you have more removals { take out the current removal using substring use indexOf to look for more removals } I need help with assignment: "String Cleaner" StringRemover.js: //(c) A+...
