You use the FileWriter and BufferedWriter class:
Class FileWriter
The FileWriter is a class used for writing character files. The constructors of this class assume that the default character encoding and the default byte-buffer size are acceptable. To specify these values yourself, construct an OutputStreamWriter on a FileOutputStream.

BufferedWriter

The BufferWriter class is used to write text to a character-output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings.


Example

import java.io.*;
class FileWrite 
{
   public static void main(String args[])
  {
      
    FileWriter fstream = new FileWriter("name.txt");        //create a file called name.txt
    BufferedWriter out = new BufferedWriter(fstream);    // create a writing stream
    out.write("Hello Java");                                        //write whatever you want
    out.close();                                                       // stops writing
    
  }
}

hehe i've just got this when I copy paste your code

ohh I forgot to right the throws IOException beside public static void main (String []args) __(>throws IOException<)__
