- This is in Java please: A comma separated value (.csv) file has been included to be used for this program. Each line contains two values, a name and a number separated by a comma (except the first line, which contains the titles for the value types). The name is that of a writer and the number refers to the number of works the writer has written. Ex. Jane Austen,6. Each line is an entry and each entry number can be updated by identifying the associated name. Once complete, the following program opens data file allWorks.csv and asks if the user wants to update entries or add new entries. All entries are stored in an array while being read in and updated. The program then writes the array to the file, overwriting the original contents. The following TODO sections must be completed. Open allWorks.csv for reading/input. Locate an entry to be updated by name (use the Java String indexOf() method) Add a new entry if the name isn't found in the file (give the entry a new number) Open file…Review the program Warning.java that reads in a file of student academic credit data.

Thefile Warning.java contains a skeleton of the program. Do the following: 1. Add the code to calculate the gpa.2. Display the name if the gpa is less than 2.0.3. Test to ensure the output is accurate.4. Add code to catch the following exceptions: • A FileNotFoundException if the input file does not exist.How will you…UOWD Library is asking you to write a Java program that manages all the items in the Library. The library has books, journals, and media (DVD for example). All items have a name, author(s), and year of publication. A journal also has a volume number, while a media has a type (audio/video/interactive). The user of your program should be able to add an item, delete an item, change information of an item, list all items in a specific category (book, journal, or media), and print all items (from all categories). A menu asks the user which operation s/he wants to perform. Important: make use of collections, inheritance, interfaces, and exception handling wherever appropriate.
- Write a Java program, GradeApp that reads a series of exam scores given as integers in the range 0 to 100. Display the total number of grades and the number of grades in each letter-grade category, followed class average (as a percentage with 2 decimal place): Use the value -1 as a sentinel value to indicate the end of the input. (The -1 value is used only to end the loop. Please do not use it in the calculations.)Write a program that generates a gradebook similar to the jenzabar grade book output: student name grade letter grade Ahmed ... 90 A- honda 99 A+ Karim 60 D- you must use tuples, list and dictionaries appropriately to get the user input for the grades the grade should include all the categories in the coursework (classwork/homework, quizzes,midterm,final, lab and attendance) the assignments type weight listed in the syllabus must be used to compute the overall class gradeCreate a java program that calculates the average test scores.

For this assignment, triangle data will be read from an input file and the program’s output will be written to another file. The output file will also include a summary of the data processed. You must use at least one dialog box in this program. The data for each triangle will be on a separate line of the input file, with the input data echoed and the results referred to by the line number (see example). On initialization, the program will prompt the user for both an input and an output file. If a non-existent input file is specified, the appropriate exception must be handled, resulting in an error message. For the exception case, re-prompt the user for the correct input file.

- Write a Java Program The local Kids’ League coach keeps some of the baseball team statistics in a text fileorganized as follows: each line of the file contains the name of the player followedby a list of symbols indicating what happened on each at bat for the player. Theletter h indicates a hit, o an out, w a walk, and s a sacrifice fly. Each item on theline is separated by a comma. There are no blank spaces except in the player name.So, for example the file could look as follows:Willy Wonk,o,o,h,o,o,o,o,h,w,o,o,o,o,s,h,o,hSam Slugger,h,h,o,s,w,w,h,w,o,o,o,h,sIn this problem you will a create a program that reads raw data from a text file andprints properly formatted statistics.

The file includes carModel , carYear, and carPrice for an unknown number of Cars. The file uses a comma-separated file format, as the sample below. The program should write New cars only into an output file called “NewCars.txt”. A car is considered new if its year is above 2019. Finally, the program should print the number of new cars, the most expensive car, and the cheapest car at the end of the output file. The format of the output file should be similar to the given sample.A java file that reads a text file, in.txt, that contains a list of positive integers a positive integer) separated by spaces and/or line breaks. After reading the integers, the program must recursively figure out if the list of integers includes two equal integers. If the list includes two equal integers, the program prints out Yes. Otherwise, the program prints out No. Assume that in.txt contains at least 2 integers. It is important that your program be named Two and that the input file is named in.txt.
