File Handling

• To handle file read and write operations, use FileHandler.java, located in: /src/main/java/com/example/demo/utils

• This class contains 4 methods, but you only need to use the following 2:

// Write new data to a file
public static boolean writeToFile(String fileName, boolean append, String data);

// Read the entire content of a file line by line into a string array
public static String[] readFromFile(String fileName);

To use the writeToFile and readFromFile methods from FileHandler.java in another file, follow these steps:

1. Writing Data to a File

To save data in a file, call writeToFile as shown below:

import com.example.demo.utils.FileHandler;

public class ExampleWrite {
    public static void main(String[] args) {
        String fileName = "users.txt";
        String data = "U001, user1@example.com, John Doe, 25, 1234567890, Male, password123";

        boolean isWritten = FileHandler.writeToFile(fileName, true, data);
        
        if (isWritten) {
            System.out.println("Data successfully written to " + fileName);
        } else {
            System.out.println("Failed to write data.");
        }
    }
}

2. Reading Data from a File

To read data from a file, use readFromFile:

import com.example.demo.utils.FileHandler;

public class ExampleRead {
    public static void main(String[] args) {
        String fileName = "users.txt";

        String[] users = FileHandler.readFromFile(fileName);

        if (users.length > 0) {
            System.out.println("Data from " + fileName + ":");
            for (String user : users) {
                System.out.println(user);
            }
        } else {
            System.out.println("No data found in " + fileName);
        }
    }
}
