This simple method shows hot to write to text files using Java.
If the file exists it will append the new text to it, otherwise it creates a new file. This is achieved using the FileWriter class and its constructor:

public FileWriter(String fileName, boolean append) throws IOException

Constructs a FileWriter object given a file name with a boolean indicating whether or not to append the data written. JavaDoc.

public void writeToFile(String text, String filePath){
 
  try {
 
    File thisFile = new File(filePath);
 
    BufferedWriter writer = new BufferedWriter(
                                new FileWriter(filePath, thisFile.exists()));
    writer.write( text );
    writer.newLine();
 
    writer.flush();
    writer.close();
 
  } catch (IOException e) {
    e.printStackTrace();
  }
}
