In Java
Suppose you are given a text file that contains the names of people. Every name in the file consistsof a first name and a last name. Unfortunately, the programmer that created the file of names hada strange sense of humor and did not guarantee that each name was on a single line of the file.Write a program that reads this file of names and writes them to a new text file, one name per line.For example, if the input file (Names.txt) contains:Bob Jones FredCharles EdMarstonJeffWilliamsThe output file (RecoveredName.txt) should be:Bob JonesFred CharlesEd MarstonJeff WilliamsSample Output:Enter the name of the input file:Names.txtEnter the name of the output file: RecoveredName.txtFile processing completed.
Write a Java program that print its own source code. Note: Don't use any file path
Write a Java program that reads in a paragraph of text from a file and prompts the user to enter a word to search for. The program should then output the number of times the word appears in the paragraph.
Here are the basic steps to implement this program:
Prompt the user to enter the name of the input file.
Read in the paragraph of text from the input file.
Prompt the user to enter a word to search for.
Search the paragraph for the word and count the number of times it appears.
Output the number of times the word appears in the paragraph.
To implement step 4, you can use a similar approach to the example I provided in class:
Split the paragraph into an array of words using the split() method.
Iterate through each word in the array and compare it to the search word (ignoring case).
If the word matches the search word, increment a counter variable.

- You should turn in FibonacciComparison.java and your plot (as a PNG). This can be a screenshot of the plot or the plot saved as a PNG file. Remember, your FibonacciComparison.java file should not be within a package other than src. This means the word "package" should not be at the top of the file signifying that the file is within a sub-directory of src. Your directory structure of your project should be: [project name] | src | | FibonacciComparison.java | | Pair.java There will be -15 points if one of the following happen: 1. Your code throws a compiler exception (meaning your code cannot be run) 2. You do not use FibonacciComparisonthe class name 3.

It will only be loading JSON files that it has previously created, so the internal organization of the data is up to you. The init method takes no parameters and initializes all the data members, which must all be private. The add_pet method takes as parameters the name of the pet, the species of the pet, and the name of the pet's owner. If a pet has the same name as a pet that has already been added, then the function should raise a DuplicateNameError (you'll need to define this exception class). The delete_pet method takes as a parameter the name of the pet and deletes that pet. The get_owner method takes as a parameter the name of the pet and…arrow_forward
