java You may NOT write this program as a GUI (Graphical User Interface). Write a program that reads a file named input.txt and writes a file that contains the same contents, but is named output.txt. The input file will contain more than one line when I test this and so should your output file. Do not use a path name when opening these files. This means the files should be located in the top level folder of the project. This would be the folder that contains the src folder, probably named FileCopy depending on what name you gave the project. Do not use a copy method that is supplied by Java. Your program must read the file line by line and write the file itself. do not write to input.txt* Your class name must be FileCopy. It should be in a package named mypackage

Develop the Music Player Experimental (MPX) as discussed in lecture.For Apple Developers you need only see the numbers align correctly, whereas Window developers use the Beep() API to hear your success. (Added a hard-coded version of the Little Lamb code.)Note Well: Your main function must be small Variables well-named Short comments Readable code Upload only the main.cpp file. I will use my own MXP file.
I NEED BulbGUI.java Using JAVA, Create a File Menu in your GUI Add a file menu to your BulbGUI with options to open any file for reading (and displaying the file as in Project 2), and one to Quit the program. You will need a FileMenuHandler class to handle the events from the FileMenu. Be sure to use getAbsolutePath() when getting the file from the JFileChooser, not getName(). Handle Exceptions Create an exception called IllegalBulbException (by extending IlegalArgumentException as shown in the lecture) and have the constructor of the Bulb throw it. For our purposes, a Bulb is illegal if the wattage is less than 5. Use a try/catch statement to catch this exception in your program, and display the erroneous Bulbs to the console (do not put them in the ArrayList). Use ArrayLists Use an ArrayList to store the unsorted Bulbs. For this project, display only the unsorted bulbs in the GUI.

Add three files of any type you choose—for example, word-processing documents,spreadsheets, or pictures.Create a new folder named test inside folder data and move your third file in this folder.Write an application that determines whether the first two files are located in the same folderas the third one. Test the program when the files are in the same folder (before moving thirdfile in test folder) and when they are not (after moving third file in test folder).Save the file as CompareFolders.java.Submit the data folder zipped along with CompareFolders.java.HINT: Use try/catch block, path class and its methods.Run a loop to check the name count.Output will look like: -Path for file1 is C:\Users\<your file path>\Lab9\TestData1.txtPath for file2 is C:\Users\<your file path>\Lab9\TestData2.txtPath for file3 is C:\Users\<your file path>\Lab9\TestData3.txtAll files are in the same folderPath for file1 is C:\Users\<your file path>\Lab9\TestData1.txtPath for file2 is…
Hi can I get help for java code for this project Part 1 of this project is basically concerned with completing methods printAllAnimals() and readDataFromFile(). The readDataFromFile() method uses a FileDialog object so that you can easily select a file to read data from, but the code for reading the data is missing. However, if you create a MyZoo object and execute the readDataFromFile() then you should see a message stating that 10 animals have been read from the file (but remember that a common problem is that the "open file" dialog gets hidden behind other windows). It doesn't matter which input file you select as no data is read from the file, instead some "temporary" code will "populate" the zoo. After executing readDataFromFile(), if you next execute the printAllAnimals() method then only a "header" will be printed -- it will not actually show any animals as this method is also incomplete. Proceed by completing the following stages. Note that no changes should be needed for class…
First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects). Then create a new Java application called "Rooter" (without the quotation marks) to get a positive integer (i.e. any number greater than 0) called "start" from the user at the command line and then find the square root of every number from "start" down through 0. Use a while loop to count down. As an example, if the user entered 8, you would find the square root of 8, then the square root of 7, and so on. Print each square root on a separate line. Include data validation to ensure the user provides a positive integer. If the validation is not passed, provide the user with suitable feedback and stay in the program to let the user try again until valid input is received. Use the Math.sqrt(double a) method to find each square root and output the integer and four decimal positions.

Find All Tasks titles that added by “Ali" sorted by id. Find the top four tasks sorted by creation date. Find all tasks that start with the letter 'a' and have exactly seven letters (ignore letter 'a' case). Find who added the largest number of tasks. Find the number of tasks that are closed and open. Count the tasks that added by "Sami".
