I started writing a notepad for Android in Java, and I was interested in how to save and open notes in a notepad.

    Reading from file:

    BufferedReader reader = new BufferedReader(new FileReader(fileName));

    FileReader - read characters from a file.

    BufferedReader - used to buffer the stream.

    Write to file:

     FileWriter fileWriter = new FileWriter(fileName);

    fileWriter can pass a whole string to fileWriter (it will automatically break into characters).

    Here is a good lecture on this topic.
