In Java, What Is The Method To Add Text To An Already Existing File?

To append text to an existing file in Java, you can use classes like FileWriter or BufferedWriter. Here’s an example:

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;

public class AppendToFileExample {
    public static void main(String[] args) {
        String filePath = "path/to/your/file.txt";

        try {
            // Open the file in append mode
            FileWriter fileWriter = new FileWriter(filePath, true);
            
            // Wrap the FileWriter in a BufferedWriter
            BufferedWriter bufferedWriter = new BufferedWriter(fileWriter);

            // Write the text to the file
            bufferedWriter.write("Text to append");

            // Close the resources
            bufferedWriter.close();
            fileWriter.close();
            
            System.out.println("Text appended to the file successfully.");
        } catch (IOException e) {
            System.out.println("An error occurred while appending the text to the file.");
            e.printStackTrace();
        }
    }
}

In this example, the FileWriter is created with the append parameter set to true, which means the text will be appended to the existing content of the file instead of overwriting it.
