### Java Word Search Exercise1. **Task Description:** - Complete the class code below and include a **method named "search"** that takes two String parameters: a string to search through and a target string to search for in the first string. - The search method will return an integer representing the number of times the search string was found. - The string being searched is a super-string formed by joining all lines of a text file, so multiple occurrences of the target string are expected. - **Hint:** Walk the String in a loop and use `.substring(start, end)` to examine a segment of the input string that is sized to match the target word.2. **Code Skeleton:**```javapublic class WordSearch { public static void main(String[] args) { String fileName = "story.txt"; String target = "help"; Scanner fileIn = new Scanner(new File(fileName)); String story = ""; while(fileIn.hasNextLine()) { story += fileIn.nextLine(); // Build a super-String } System.out.println("(" + target + ") found " + search(story, target) + " times"); } // method code here} // end of WordSearch class```3. **Explanation:** - **Purpose:** This exercise involves completing a Java program that reads from a text file, concatenates its contents into a single large string (super-string), and then searches for occurrences of a target substring within this super-string. - **Key Components:** - **Scanner:** Used for reading the text file line-by-line. - **String Concatenation:** Each line from the file is appended to a `String` to form the super-string. - **Search Method:** Needs to be implemented to count how many times the `target` string occurs within the `story`.4. **Expected Outcome:** - The program will output how many times the string "help" appears in the concatenated text from "story.txt".

1. Complete the class code below and include a method named "search" that takes two String.parameters, a string to search and the other a target string to search for in the first string. The search method will return an integer representing the number of times the search string was found. The string being searched is a super-string formed by joining all lines of a text file, so we might expect to get multiple hits with our method. HINT: walk the String in a loop and use .substring(start, end) to examine a target-sized segment of the input string for equality to your target word. public class WordSearch { public static void main(String[] args) { String fileName = "story.txt"; String target = "help"; Scanner fileln = new Scanner(new File(fileName)); String story = ""; while(fileln.hasNextLine()) { story += fileln.nextLine(); // Build a super-String } System.out.printIn("(" + target + ") found " + search(story, target) +" times"); } // method code here } I/ end of WordSearch class

Description is " A MathVector object will be passed to your method. Return its contents as a String. If you look in the file MathVector.java you'll see there is a way to output the contents of a MathVector object as a String. This makes it useful for displaying to the user. You might have noticed that there's an @override term there. That's because many objects already have a "toString()" method associated with them... because Java was designed to include them by default. Here, the override tells Java "I know, I know. You already have a toString() that you'd assign here. But it's not good enough. Here's a better one for this particular kind of object." It's a little bit like saying "Most humans have two legs. So, by default, I'll give everyone two legs. But sometimes we override that and give no legs, or just one leg to a person. And sometimes we give them four so that they can be a centaur!" To use this in a println() method, just name your object. The toString()…

PATTERNS: Shapes Using Python, recreate (as close as possible) the pattern given using only one class - the Pattern class. You are only allowed to use PIL.Image and PIL.ImageDraw from the Pillow Library, and pi, cos, and pi. Its data attributes are as follow: width_height – 2-digit tuple containing the width and height of the image space – Image object (with 8-bit RGB color space, specified size, and background color) draw – Image object that performs as the drawing context of the space background – 3-digit tuple of the 8-bit RGB background color of the image or picture
a textbox for an optional search term, and a file upload field which allows them to upload a file which contains multiple lines of text (with the file each line should be treated as a separate string). The user can enter a string and upload a file in the same submission of the form. For the single string: if a search term is provided, output the string with the search term highlighted (by wrapping the term in a span with an appropriate class). For the file upload:, if a search term is provided output only the strings that contain the search term (with the search term highlighted) and a count of the number of strings that did not have the term. please do this in PHP and HTML only
3. Create a program for Smalltown Regional Airport Flights that accepts either an integer flight number or string airport code from the options in Figure 8-33. Pass the user’s entry to one of two overloaded GetFlightInfo() methods, and then display a returned string with all the flight details. The method version that accepts an integer looks up the airport code, name, and time of flight; the version that accepts a string description looks up the flight number, airport name, and time. The methods return an appropriate message if the flight is not found. Farrell, Joyce. Microsoft Visual C#: An Introduction to Object-Oriented Programming (MindTap Course List) (p. 347).

Create 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)
In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…

1. A method called convertFromDecimal which takes two integers as parameters. The first integer is the decimal number to be converted and the second integer is the base to be converted to. The base value could be any number between 2 (binary) and 16 (hexadecimal). The converted number is returned as a String. Hints: • Remember that in order to convert a decimal number that includes only an integer part to a base n, you need to use repeated integer division of successive quotients on n saving the remainder in each step until the quotient is zero. • Remember that numbering systems with bases 11-16 use letters in order to continue counting after the digit 9. For example, the numbering system with base 12 has the following digits: {0,1,2,3..9,A,B}. ...... 2. In your main method declare and initialize an integer. Then print its representation in all numbering systems from 2-16 by invoking the method convertFromDecimal. You should use a for loop for this part.
