creating a constructor for file creation

Question

I am writing a program based on file. My code looks something like this,

   public class clazz {
    void somemethod() {
        StringBuffer s = new StringBuffer();
        // some code at final
        write(buf);
    }

    void write(StringBuffer buffer) {
        FileWriter f = new FileWriter(fileName);
        BufferedWriter b = new BufferedWriter(f);
        // implemented write, flush, close
    }
}

when I call somemethod method, the file gets open every time. I need to open the file once using constructor and reuse the BufferedWriter. Help me regarding this.

It looks like something that your adviser told you to do and you have no clue.

Make BufferedWriter a instance variable
Initialize it in your constructor.
