Chapter 12.1, Problem 2STQ
Program Plan Intro
“set” method in “ArrayList” class:
- • This method is used to replace the value at the position specified by index with the given value.
- • Users can replace any existing element for a particular index using “set” method.
Example:
The example for replacing string for index “4” is given below:
Consider, “nameList” is an object of class “ArrayList<String>”.
User can replace the string “Rose” to the list “nameList” at index “4” which is given below:
nameList.set(4, "Rose");

Question 10
Create a class that implements a compressed trie for a set of strings. The class should have a constructor that takes a list of strings as an argument, and the class should have a method that tests whether a given string is stored in the trie. JAVA PLZ!
. . .
Write code that creates an ArrayList that can hold String objects. Add the names of three cars to the ArrayList, and then display the contents of the ArrayList.
In this programming challenge, you will create a simple trivia game for two players. The program will work like this: • Read the contents of the trivia.txt file into an ArrayList . • Starting with player 1, each player gets a turn at answering one trivia question. (For instance, if there are 10 questions, 5 for each player.) When a question is displayed, four possible answers are also displayed. Only one of the answers is correct, and if the player selects the correct answer, he or she earns a point. • After answers have been selected for all of the questions, the program displays the number of points earned by each player and declares the player with the highest number of points the winner, same as the sample execution. You are to design a Question class to hold the data for a trivia question. The Question class should have String fields for the following data: • A trivia question • Possible answer 1 • Possible answer 2 • Possible answer 3 • Possible answer 4 • The number of the…

- It is a class that is part of the java.util package which can store a list of values and reference them with an index. (a) None of the Choices (b) Variable List (c) Array List (d) Object List Please provide an explanation. Thank you!arrow_forwardIn C++, first, make a set with 10 objects, then ask the user to enter a value for search in your list. if the value exists then print "the value you are looking for that is in the set", otherwise print "The value you are looking for that is not in the list".arrow_forwardWrite a program named Search.java that uses a function called search_string to check whether a string exists in the array or not. 1- The array of strings is iterated using a for loop and the value at every index is compared with the value to be searched in the array. 2- A boolean variable is set if any array value matches with the string. 3- At the end of the loop, this boolean variable is checked to determine if the array contains the string. Hint: You may need to import java.util.Arrays then use Arrays.toString, String equals(). The ouput should look like what is pictured below. Please provide an editable code that is easy to copy and paste.arrow_forward
- Can you all please help me with this data structure question the language is Javaarrow_forwardP1: Name Search. Download the text file names.txt attached below. It contains a list of 65 female first names in upper case letters. In Eclipse, insert this file into your Java project folder. Implement two static methods: • tringSort: It will sort the String array provided as an argument using one of the sorting algorithms presented in class (selection or insertion). • stringSearch: It will search the String array provided as its first argument for the String value provided as its second argument using the binary search algorithm presented in class. The main method reads the 65 names from the file names.txt and inserts each one into an array. This array is then sorted using the stringSort method. The stringSearch method is then used to search for different names inputed by the user.arrow_forwardYou have a list of student ID’s followed by the course number (separated by a space) that the student is enrolled in. The listing is in no particular order. For example, if student 1 is in CS100 and CS200 while student 2 is in CS105 and MATH210 then the list might look like this:1 CS1002 MATH2102 CS1051 CS200Write a program that reads data in this format from the console. If the ID is −1 then stop inputting data. Use the HashMap class to map from an Integer (the student ID) to an ArrayList of type String that holds each class that the student is enrolled in. The declaration should look like this:HashMap<Integer, ArrayList<String>> students =new HashMap<Integer, ArrayList<String>>();After all data is input, iterate through the map and output the student ID and all classes stored in the vector for that student. The result should be a list of classes organized by student ID.arrow_forward
- You can check whether a string is a substring of another string by using the find method in the str class. Write your own function to implementfind. Write a program that prompts the user to enter two strings and then checks whether the first string is a substring of the second string.arrow_forwardIn the C programming language Suppose you are given an array of integers. You want to insert a number x to the array and rearrange so that all the elements are less than or equal to x are before x, and the elements after x are greater than x. For example, suppose the list is {3, 2, 7, 0 1, 5}and x is 4, since3, 2, 0, and 1,are less than or equal to 4,7and 5 are greater than 4, the new array is {3, 2, 0, 1, 4, 7, 5}.The new array has the length of n+1 where n is the length of the input array. Example input/output #1: Enter the length of the array: 10 Enter the elements of the array: 3 5 14 03 92 8 11 Enter the number for insertion: 3 Output: 3 1 0 3 2 3 5 4 9 8 11 Example input/output #2: Enter the length of the array: 8 Enter the elements of the array: 5013 4 1 7 3 5 Enter the number for insertion: 6 Output: 5 0 4 1 356 13 7 1) Name your program arrays.c 2) Include the rearrange( ) function to rearrange the array: void rearrange(int *a, int n, int insert, int *b); a…arrow_forwardHow do you do this?
