- Computer Science Consider a look-up service for the television shows on a given date. A file contains information about these shows. Each show’s data appears on two lines. The first line gives the name of the station, the channel, the name of the show, and a rating. These entries are separated by tildes (~). The second line briefly describes the show. Write pseudocode for a method with the header public void readFile(Scanner data) to read the file into a dictionary that will be searched. Decide what data should be the search key and what should be the associated value. Design any classes needed for the key and the value. Write pseudocode for the method Do not write any code for the answer. Use UML, pseudocode, and written Description.Basic Java Help Each year, the Social Security Administration provides a list of baby names for boy and girls by state. You will write a program to read a file containing a list of baby names and display the top names. To start, implement the following class: baby names util = printTopNames(File, int): void printTopNames Will be a static method. It will accept two parameters, one is a File containing the list of names. The other is an integer that indicates how many names to display (ie, top 10 names, or top 50 names, etc). The integer argument could be any valid integer. You do not have to worry about an integer value large than 5 for the boy/girl names. This method should open the file and parse the file and print the names as shown below: Your program will use the Scanner class to read the data from the file (see your text for examples). You will also need to use a delimiter with the scanner so that the scanner will break the line apart based on the commas. For this file, set…Program62.javaWrite a program that prompts for a full name (first and last) and assigns it to one string. The program then passes the full name to a void method as its sole parameter. The void method should print the first name, on one line, as many times as indicated by the length of the last name. Sample Output (image below)
- Lab Task 04: Include the methods in the file KMP_Implementation.txt in a complete Java program that prompts for and reads a text string and then a text pattern to search for in the text. It then displays the result of the search. Sample program runs: Enter the text: ABABСАВАВАВСАВАВСАВАВСАВАВКККАВАВСАВАВ Enter the pattern to search for: ABABCABAB Pattern found at these text starting indexes: 0 Enter the text: A KFUPM STUDENT Enter the pattern to search for: KFE Pattern not in text. 7 12 17 29Problem 1: Create a Java class RecursiveMethods.java and create the following methods inside: ALL THE METHODS NEED TO BE COMPLETED RECURSIVLY. NO LOOPS ALLOWED. oddEvenMatch Rec: the method takes an integer array as a parameter and returns a boolean. The method returns true if every odd index contains an odd integer AND every even index contains an even integer(0 is even). Otherwise it returns false. sumNRec: The method takes an integer array A and returns the sum of all integers in the parameter array. nDownToOne: Takes an integer n and prints out the numbers from n down to 1, each number on its own line. inputAndPrintReverse: Inputs integers from the user until the user enters 0, then prints the integers in reverse order. For this method, you may NOT use an array or any type of array structure, in other words, you may not use any structure to store the user input. After completing the methods, use the main method to test them. You can hard code the tests.The file Parameters.java contains a program to test the variable-length method average.1. Read the code. Fill in the code to compute mean1 and mean2. Notice that you are calling the same method, but with a different number of parameters. 2. Add a call to find the average of a single integer, say 8. Print the result of the call. Is the result what you expected?3. Add a call with an empty parameter list and print the result. Is the result what you expected?4. Add a method called minimum to return the minimum value of the parameter list. Invoke this method in the main() and test it with different input numbers. //*******************************************************// Parameters.java//// Illustrates the concept of a variable parameter list.//*******************************************************import java.util.Scanner;public class Parameters{ //----------------------------------------------- // Calls the average and minimum methods with // different numbers of parameters.…

Implementation details You will implement this program in a specific way in order to gain some experience with loops, arrays and array lists. Use an array of strings to store the 4 strings listed in the description. Use a do-while loop for your 'game engine'. This means the game starts once the user enters money. The decision to stop occurs at the bottom of the loop. The do-while loop keeps going until the user quits, or there is no money left. The pseudocode for this 'game engine' is shown below: determine the fruits to display (step 3 below) and print them determine if there are 3 or 4 of the same image display the results update the customer balance as necessary prompt to play or quit continue loop if customer wants to play and there's money for another game. Use the Random class to generate a random number between 0 and 3. This random number will be an index into the array of strings. Add the string at that index to an…Write a recursive method that displaysa string reversely on the console using the following header: public static void reverseDisplay(String value) For example, reverseDisplay("abcd") displays dcba. Write a test programthat prompts the user to enter a string and displays its reversal.
- Create a class named RecusiveMethod having a recursive method. The recursive method accepts an integer argument and displays all even numbers from 1 up to the number passed as an argument. For example, if 25 is passed as an argument, the method will display 2, 4, 6, 8, 10, 12, 14, ……24. Demonstrate the method.Use for loop in Java language Write the method stringSplosion().* * The method takes one parameter, a non-empty String str (such as "Code") and* returns a String in the form "CCoCodCode". Notice that this includes the* first character of the original String, followed by the first two characters,* and so on until the whole String is used.* * Examples: stringSplosion("Code") returns "CCoCodCode" stringSplosion("abc")* returns "aababc" stringSplosion("x") returns "x"* * @param str the input String to process.* @return a new String as described above.Code with comments and output screenshot. Thank you!! Write a java method that receives a string containing letters of the English alphabet and then prints the Letters having unique frequencies. Notes: 1) Ignore letter case; Uppercase and lowercase letters are considered the same. 2) Do not use methods from the Arrays class.
