allora, classettina :

import java.io.*;
import java.util.StringTokenizer;

public class FileHelper {

	public static void copy(String orig, String dest) {

		try {

			FileInputStream  in = new FileInputStream(orig);

			BufferedInputStream  bin = new BufferedInputStream(in);

			FileOutputStream out = new FileOutputStream(dest);

			BufferedOutputStream bout = new BufferedOutputStream(out);

			int i;

			while ((i=bin.read()) != -1) {

				bout.write(i);
			}

			bout.flush();

			in.close();

			bin.close();

			out.close();

			bout.close();
		}

		catch (FileNotFoundException e){

			e.printStackTrace();
		}

		catch (IOException e) {

			e.printStackTrace();
		}

		catch (Exception e) {

			e.printStackTrace();
		}
	}

	public static void write(String str, String file) {

		try {

			FileWriter f = new FileWriter(file);//Per append [new FileWriter(file, true);]

			f.write(str);

			f.close();
		}

		catch (Exception e) {

			e.printStackTrace();
		}
	}

	public static String read(String file) {

		String str = new String();

		StringBuffer out = new StringBuffer();

		try {

			FileReader f = new FileReader(file);

			BufferedReader br = new BufferedReader(f);

			while ((str = br.readLine()) != null) {

				out.append(str);

				out.append("\n");
			}

			br.close();

			f.close();
		}

		catch (FileNotFoundException ex) {

			ex.printStackTrace();
		}

		catch (IOException ex) {

			ex.printStackTrace();
		}

		return out.toString();
	}

	public static String deleteExtension(String filename) {

		StringTokenizer stFile = new StringTokenizer(filename, ".");

		int i = stFile.countTokens();

		String filenameXML = "";

		for (int j = 0 ; j < i - 1; j++) {

			if (!filenameXML.equals("")) {

				filenameXML += ".";
			}

			filenameXML += stFile.nextToken();
		}

		return  filenameXML;
	}

	public static String getExtension(String filename) {

		StringTokenizer stFile = new StringTokenizer(filename, ".");

		int k = stFile.countTokens();

		String extension = "";

		for (int j = 0 ; j < k - 1; j++) {

			stFile.nextToken();
		}

		extension = stFile.nextToken();

		return extension;
	}

	// Per copiare una cartella
	/*try {

		Process proc = Runtime.getRuntime().exec("xcopy d:\\prova 
d:\\pippo /e /i /q");
	}

	catch (Exception e) {
	}*/
}

e poi metodino salva, che ti propone anche dove salvare :

 

private void salvaConNome() {
			JFileChooser jFileChooser = new JFileChooser();
			File file = new File("");
			int returnVal = jFileChooser.showSaveDialog(this); 
			if (returnVal == JFileChooser.APPROVE_OPTION) { 
				try{
					file = jFileChooser.getSelectedFile(); 
					
					FileHelper fh = new FileHelper();
					fh.write(jTextArea_TUATEEXTAREA.getText(),file.getAbsolutePath());
					/*
					Writer out = new FileWriter(file);
					jTextArea_TUATEEXTAREA.write(out);
					out.close();
					*/
					
									
				}catch(Exception e){
						e.printStackTrace();
				}
			} 
		}
