- Use Scanner and File to read input from a file. Use PrintStream and File to write output to a file. Write and call methods that accept parameters and return values to manage information flow and add structure to programs. Follow prescribed conventions for spacing, indentation, naming, and comments. Notice that if an input file is not found, either for creating a mad-lib or viewing an existing one, the user is re-prompted. No re-prompting occurs for the output file. If the output file does not already exist, it is created. If it does already exist, its contents are overwritten. (These are the default behaviors in Java.) You may assume that the output file is not the same file as the input file. When you are viewing an existing mad lib story, you are simply reading and echoing its contents to the console. You do not need to do any kind of testing to make sure that the story came from a mad lib input file; just output the file's contents.

You will need to perform the following steps. Prompt the user for the name of a file to append to and then another prompt for them to enter a sentence. Open the file they requested in append mode and write the user_sentence to this file. Don't forget to close the file when you are done writing to it (explicitly or implicitly). Open the file you just wrote to in read mode and read the contents of the file. Print the complete file contents to the console/shell. Provide comments in your code to explain the logic used. Ensure your program works as expected by testing it with different sentences.arrow_forwardWhat exactly is a file? What is the purpose of "opening" and "closing" a file?
