- Write a code snippet that will create an object called filout for writing, associate it with the filename STRS. Thecode should keep on writing strings to it as long as the user wants.Write a program that reads the contents of the two files into two separate lists. The user should be able to enter a boy’s name, a girl’s name, or both, and the application will display messages indicating whether the names were among the most popular. your program should read the files into separate lists for boys and girls names the program should accept either a girl name or a boy name or both, entry of a NULL i.e. just pressing the "enter key" results in no search for that entry the program must continue to run until told to stop by the person running the program using any method of your choice report on the success or not of each attempt to locate a name in the popular names filesCreate a list of 5 words, phrases and company names commonly found in phishing messages. Assign a point value to each based on your estimate of its likelihood to be in a phishing message (e.g., one point if it's something likely, two points if modereratly, or three points if highly likely). Write an application that scans a file of text for these terms and phrases. For each occurance of a keyword or phrase within the text file, add the assigned point value to the total points for the number of occurences and the point total. Show the point total for the entire message. (Write the program in Java)
- Your goal is to implement an application that reads a file, modify its content, and writes the modification back to the same file. The file includes 2 lines of integers. The first line indicates which integer on the second line has been selected (active). And the second line lists all the integers in the list (maximum of 10). Your application should have a menu that is constantly displayed on the screen (see the menu below). Right below the menu, the program should display list of all integers in the file (second line). Also, it should show which integer is currently selected (active) by displaying an arrow to its left. The user should be able to select a menu item by entering its associated key and pressing the Enter key on the keyboard. “Select Down” selects the next item in the list. If the item at the end of the list is selected, this option selects the first item in the list. “Select Up” selects the previous item in the list. If the first item is selected, this option selects the….Write code for below problem. The input below is just an example and you should implement independent from the input. Please paste the link to the answer shared using pastebin, dotnetfiddle, jsfiddle, or any other similar web-site. You will have an orthogonal triangle input from a file and you need to find the maximum sum of the numbers according to given rules below; 1. You will start from the top and move downwards to an adjacent number as in below. 2. You are only allowed to walk downwards and diagonally. 3. You can only walk over NON PRIME NUMBERS. 4. You have to reach at the end of the pyramid as much as possible. 5. You have to treat your input as pyramid. According to above rules the maximum sum of the numbers from top to bottom in below example is 24. *1 *8 4 2 *69 85*9 3 As you can see this has several paths that fits the rule of NOT PRIME NUMBERS; 1>8>6>9, 1>4>6>9, 1>4>9>9 1 + 8 + 6 + 9 = 24. As you see 1, 8, 6, 9 are all NOT PRIME NUMBERS and walking over these yields the…write the code to lookup, add and remove phoneentries from the phonebook text file . These are the code we use for the lookup, add and remove in the case statement.(Lookup)# Look someone up in the phone bookgrep $1 phonebook (add)echo "$1 $2" >> phonebooksort -o phonebook phonebook (Remove)grep -v "$1" phonebook > /tmp/phonebookmv /tmp/phonebook phonebook Write a complete Bash script which will accept up to three command-line arguments: the first one is either (lookup, add or remove), the second one is a name enclosed in single quotes and the third one (if doing an add) is a phone number enclosed in single quotes. Using a case statement to match on either lookup, add or remove, the script should then perform the requested operation. Again here, you should first check for null arguments before continuing with the rest of the script or requested operation. In addition, the person may not be in the phonebook for lookup or remove so, you need to account for this.
- IN JAVA ONLY PLEASE. POSITIVE REVIEW WILL BE LEFT FOR CORRECT LANGUAGE ONLY AND NOT COPY PASTE FROM INCORRECT ANSWER 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. Ex: If the input of the program is: ParkPhotos.txt and the contents of ParkPhotos.txt are: Acadia2003_photo.jpg AmericanSamoa1989_photo.jpg BlackCanyonoftheGunnison1983_photo.jpg CarlsbadCaverns2010_photo.jpg CraterLake1996_photo.jpg…You are given a text file (Words.txt) containing 50 words that will be hard to make out because they have been littered with punctuation. Your task is to: • Create a new file called Words2.txt, from Words.txt, which contains all the strings from the previous file, with their position, but with all the punctuation removed. (You must create some sort of method that can loop through the words to do this, you are not allowed to use Regex Patterns) Hint: This might come in handy String punctuation = "!\"#$%&'()*+,-./:;<=>?@[\\]^_`{|}~"; • You must find the first longest word that appears in the text file with their position retained as well as indicating the number of characters therein, the formatting for this can be seen in Table 1.Create a text file of names, (3 names per line, 5 lines in total) followed by an age for each name. Go through the file and sum the ages. Create an output file with each persons name followed by age and then a line at the end of the output file that says “sum of all ages is: x”. Simple Java programming. Should include things like bufferedReader, fileReader, printWriter, fileWriter, file close, try-with-resources, Scanner, catch/try, etc. Include Java file and txt file. Thank you.
- When it loads, the list of car objects should be created by reading from the above file. When Add Car button is clicked the following screen should appear: a Add a New Car Model: Year: Çolor. Mleage: Cancel Add When the user fills out new car information and clicks "Add", the new car object is created, the form is closed, so that the main form is shown again, and the newly created car object is added to the list of cars. When "View cars" button is clicked, the following form shows, displaying all car objects currently in the list (use Getlotel) function here. You will also have to send the list of cars from the main form to tis form. To do this in the view form have a public variable for list of cars, and assign to it the list of cars from the main form). ag View Cars Model: Accord, Year.20166 Year. 20166, Color: Blue, Mieage: 0 Model: Passat, Year:2014 Year: 2014, Color: White, Mileage: 20000 CloseYou must now write a method readVehicleData() in the ReservationSystem class, that reads this data, creates corresponding Vehicle objects and adds those objects to vehicleList.
