In A Class Named ReadAndEditFile Java
In A Class Namedreadandeditfilejava Use The Following Prompt To Get
In a class named ReadAndEditFile.java, prompt the user for the file name with the question: “What is the name of your file?” If the specified file does not exist, display “File Not Found” followed by the file name and prompt the user again until a valid file name is provided. Once a valid file is read, process its contents by capitalizing the first letter of the entire file and the first letter after every period. Additionally, correct spacing by removing duplicate spaces so that only one space exists between words. Finally, write the processed text to a file named HomeworkOutput6-2.txt.

In A Class Namedreadandeditfilejava Use The Following Prompt To Get
This paper discusses the implementation of a Java program designed to read a user-specified file, process its contents by correcting capitalization and spacing errors, and then output the modified text to a new file. The program features input validation, ensuring that the file exists before attempting to read it. It repeatedly prompts the user until a valid filename is provided. Once the file is successfully read, the program performs several text manipulations: capitalizing the initial letter of the entire content, capitalizing the first letter after every period, and normalizing spaces to ensure only a single space separates words. These enhancements improve the readability and formatting of the text, demonstrating effective file handling, string processing, and user interaction in Java.
Implementation
The core logic of this Java program revolves around three main components: user input validation, text processing, and file output. First, the program prompts the user for a filename using a Scanner object. To handle invalid filenames gracefully, it employs a loop that continues to prompt until the specified file exists. The existence check is performed using the File class and its exists() method. If the file does not exist, the program outputs an error message and prompts again.
Once a valid file is identified, the program reads the entire content into a String. It uses BufferedReader for efficient reading line-by-line, concatenating the lines with appropriate spaces. After reading, the text undergoes processing to correct capitalization and spacing.
Firstly, the entire text is converted to lowercase, then the first character is capitalized to ensure the initial letter in the file is uppercase. Secondly, the program searches for each period followed by spaces, replacing the period and any spaces with a period followed by a space, and capitalizes the first letter after each period to denote the start of a new sentence.
The spacing correction involves replacing multiple spaces with a single space using regular expressions. This normalization ensures the text does not contain unnecessary whitespace.
Finally, the processed string is written to the output file named "HomeworkOutput6-2.txt" using a BufferedWriter, ensuring the formatted content is saved properly.
This approach combines robust input validation, precise string manipulation, and streamlined file I/O operations, exemplifying best practices for text processing in Java.
Conclusion
This Java program effectively demonstrates how to handle user input, validate file existence, process textual data—including capitalization and spacing corrections—and output to a new file. Such techniques are essential in automating text formatting tasks, developing user-friendly interfaces, and managing file I/O operations. Building upon fundamental Java concepts like loops, conditionals, regular expressions, and string handling, this implementation provides a comprehensive example suited for learners and developers aiming to improve text processing skills.
