    Java provides robust support for file handling through the java.io package, enabling developers to perform operations like reading, writing, and manipulating files. Below are the key methods to handle file I/O in Java.

    1. Creating a File

    To create a file, use the File class and its createNewFile() method.

    import java.io.File;
    import java.io.IOException;

    public class CreateFile {
    public static void main(String[] args) {
    try {
    File file = new File("example.txt");
    if (file.createNewFile()) {
    System.out.println("File created: " + file.getName());
    } else {
    System.out.println("File already exists.");
    }
    } catch (IOException e) {
    System.out.println("An error occurred.");
    e.printStackTrace();
    }
    }
    }
    Cóipeáilte!

    2. Writing to a File

    Use the FileWriter class to write data to a file.
