- ReadInstructor. The class will: – Create an array of instructor objects – Read the instructors.txt file – Create an Instructor object for each line of input and store the object in the array. – After closing the file, it will print out a line for each instructor in the array. Input file:Mary Smith 1991 50000.00 John Jones 2000 90000.00 Terry Seidel 1992 51000.00 Jessica Terrell 2000 91000.00arrow_forward1-Write a JAVA program that reads an array from input file and invokes twodifferent methods Sort and Max ,that sorts the elements of the array and findsthe Max element and writes out the resulted array in to output file .

The name must not be an empty string. The name also must not include any numbers or symbols. The balance must be zero or more to be used.If the name was an empty string a Value Error will be raised with the message “name cannot be empty”If the name contained numbers or symbols a Value Error will be raised with the message “name cannot include numbers or symbols”If the name was valid, it will be formatted properly and assigned to the instance variable. The valid name consists of alphabetical characters lowercase or upper case, may include space, underscore or hyphen.The name may consist of first, middle and last name.One way to validate the name is using Regular Expressions.Proper name format is the first character uppercase and the rest of the name lowercase character.…arrow_forward
- True/ False 1- Class objects can be defined prior to the class declaration. 2- You must use the private access specification for all data members of a class. 3- If an array is partially initialized, the uninitialized elements will be set to zero. 4- A vector object automatically expands in size to accommodate the items stored in it. 5- With pointer variables, you can access but not modify data in other variables. 6- Assuming myValues is an array of int values and index is an int variable, both of the following statements do the same thing. 1. cout header file. 15- To solve a problem recursively, you must identify at least one case in which the problem can be solved without recursion.arrow_forwardWAP to demonstrateuser defne exception create InsufficientBalanceException class create cust class if(withdrawlamt > avabal)---->throw InsufficentBalException else------------>collect the amtarrow_forwardJava Program Fleet class- reading from a file called deltafleet.txt-Using file and Scanner Will be creating a file called newfleet.txt Instance Variables:o An array that stores Aircraft that represents Delta Airlines entire fleeto 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 zeroo readFile()- This method accepts a string that represents the name of the file to beread. It will then read the file. Once the data is read, it should create an aircraft andthen pass the vehicle to the addAircraft method. It should not allow any duplicationof records. Be sure to handle all exceptions.o writeFile()- This method accepts a string that represents the name of the file to bewritten to and then writes the contents of the array to a file. This method shouldcall a sort method to sort the array before writing to it.o sortArray()- This method returns a sorted array. The array is…arrow_forward
- Java OOP Write a complete address book maintenance application. The user of the program has four options: Add a new person, delete a person, modify the data of a person, and search for a person by giving the name. Use the AddressBook class, either the original one from the chapter or the modified one from the previous exercises. You have to decide how to allow the user to enter the values for a new person, display person information, and so forth.arrow_forwardComputer Science In java design 2 classes, one where you design a Car object with 3 features, doors, windows and seats. Include one toString method that returns how much you have for each feature. This is NOT serializable, the file is .txt In the second class, create a client class, where you have an existing file, which already has 2 car objects in it, delete the second line with the car object, so there is only 1 and then write in the file 4 car objects from the Arraylist. DO NOT use colons ":" in your work . Explain all steps of your work and display an output. Don't use buffer reader or file reader. Use Scanner when reading a file, below are the imports you can use, YOU can also use any type of error message import java.io.FileWriter;import java.io.IOException;import java.io.PrintWriter; import java.util.Scanner here is a example of scanner if needed Scanner file = new Scanner( new File("flights.txt" ) );arrow_forwardCLASSES, DYNAMIC ARRAYS AND POINTERS Define a class called textLines that will be used to store a list of lines of text (each line can be specified as a string). Use a dynamic array to store the list. In addition, you should have a private data member that specifies the length of the list. Create a constructor that takes a file name as parameter, and fills up the list with lines from the file. Make sure that you set the dynamic array to expand large enough to hold all the lines from the file. Also, create a constructor that takes an integer parameter that sets the size of an empty list. in C++ Write member functions to: remove and return the last line from the list add a new line onto the end of the list, if there is room for it, otherwise print a message and expand the array empty the entire list return the number of lines still on the list take two lists and return one combined list (with no duplicates) copy constructor to support deep copying remember the destructor!arrow_forward
- Word Puzzle GameIn this assignment is only for individual. You are going to decode the scrambled word into correct orderin this game. One round of play is as follows:1. Computer reads a text file named words.txt2. Computer randomly picks one word in the file and randomly scrambles characters in the wordmany times to hide the word3. Computer displays the scrambled word to user with indexes and gives the user options to1. Swap two letters in word based on index given2. Solve the puzzle directly3. Quit the game4. If a player chooses to swap letters, the computer reads two indexes and swaps the letters. Thegame resume to step 3 with the newly guessed word. If the resulted word after swapping is thesecret word, the game is over.5. If a user chooses to solve directly, computer prompts the user to enter the guessed word. If it’scorrect, the game is over, otherwise goes to step 3.6. After game is over, display how many times the player has tried to solve the puzzle.The following is sample…arrow_forwardC++ Write a code segment that creates an ofstream object named outfile, opens a file named numfile.txt, and associates it with outfile. Then write the contents of the variable data to the file, followed by a newline, then close the file.arrow_forwardin c++ Write a function named createTwoNames that will do the following: - Read in a word and its definition - Create the Word object for that word and definition - Read in an item’s name and its price - Create the Item object for that item - It will return an array of two pointers pointing to these newly created Word and Item objects. It will use try-catch statement to handle the exception. If the user enters an empty or all-blank word or definition or item’s name, it will not create the object(s) and return null for that object only. In another words, it may create 0, 1 or 2 objects. Whenever the error occurs, it must print out the correct error reason: empty or blank (but not both). Note that this function can and will use cin and cout to read in values from the user.arrow_forward
