In java Browse Project Gutenberg (https://www.gutenberg.org/) for plain text versions of one or more works of literature of your choosing. Write a program that repeatedly searches a file for a target word or phrase.• Allow the user to supply the name of the file to search by means of a command-line argument; if the user does not supply a command line argument, ask for a file name interactively.• You may use either an array or an ArrayList to store each line in the file; but if you use an array, you’ll have to determine the array size (number of lines) before allocating the array. There are several ways to do this.• Report how many lines were read from the file.• Search for either individual words or phrases (Hint: use the .contains method, it’ll work for either a word or a phrase)• Show both the line number and the line itself for each line that contains the search target entered by the user (you may count the first line in the file as line 0).• If a search word is part of a larger…

Please help me code in java: Write a program that reads two files “Data1.txt”, “Data2.txt”; adding their corresponding elements produces an output file “output.txt”. If the number of elements are not equal, fill the elements of the smaller file up with “0” s. Sample output: Elements of the “Data1.txt”: 3 5 7 8 9 Elements of the “Data2.txt”: 45 11 Elements of the “Output.txt”: 48 16 7 8
Write a program that takes an integer array and perform following operations sum, average, percentage,. The user must non zero integers. If they were not an integer, the program would throw a NumberFormatException if user try to input string instead of integer value. If denominator were Zero, the program would throw an ArithmeticException and Display the exception.

You are requested to develop a simple java program for a movie theatre. They need to store the following information: Movie name, year, genre, rating. The values are saved in txt files (choose any movies you like). Read the values from the txt files and store them in parallel arrays. Then calculate/ Find the following: - The highest rating movie. - The lowest rating movie. - The oldest movie. - The average rating for a chosen genre.
Write a Java program with a single-dimension array that holds 10 integer numbers and identify the maximum value of the 10 numbers. Next sort the array using a bubble sort and display the array before and after sorting.

Write a program in java that will continue to prompt the user for numbers, storing them in an array, until they enter "Done" to finish, then prompts the user for a file name so that these values can be saved to that file. For example, if the user enters "output.txt", then the program should write the numbers that have been read to "output.txt".
