我如何使用FileWriter实际写入文件,然后在记事本上打开它,看看我写了什么？这是我到目前为止所尝试的:

package Experimental;

import java.io.*;

public class IO {

    public static void main (String args[]) {

       File f = new File("testFile.txt");

       //Outputting into a file
       try {

          PrintWriter filePrint = new PrintWriter(
             new BufferedWriter(new FileWriter(f,true))
          );
          filePrint.println("testing, testing, printing into a file (apparently)");
       } catch (IOException e) {
          System.out.println(e.getMessage());
       }
   }
}
