Java: Read text from a file that was previously selected in another class

Question

Using JavaFX, I have the user input information into text fields. My MainController class allows the user to save that inputted text to a txt file and save it at a given location.

Im wondering if its possible to pass what was entered in that text file into another class so I can parse and have my program use its data.

I used strings and .getText() then used a filewriter and bufferedWriter. Can I get the .getText input into another class?

Yes. Why do you think this is not possible? What kind of issues do you expect? If you're asking about fxml in particular your question is a duplicate of this one: https://stackoverflow.com/questions/14187963/passing-parameters-javafx-fxml — fabian, Nov 14 '17 at 17:27

If your class is public than yes,you can use it in any class in your application;

public void Button2Action(ActionEvent event) throws IOException { String name1 = name.getText(); For example. And my other class is employee.java Sorry, been trying to figure this out – Chris Nov 14 '17 at 01:47
when you create a class ,if it has no errors ,its the same as the other built in classes ,you can use them anywhere ,and create objects in other classes – Nov 14 '17 at 01:50

You should research for Java - Access Modifiers

but as an ideia,

public class MainController {

    private String savedFilePath;

    public String getSavedFilePath() {
        return savedFilePath;
    }

    public void setSavedFilePath(String savedFilePath) {
        this.savedFilePath = savedFilePath;
    }
}

and from the other class, when you save the file you can call:

MainController controller = new MainController();
controller.setSavedFilePath("file path");

If you don't want to create a new object MainController, you can define the savedFilePath as static

public class MainController {

    private static String savedFilePath;

    public static void setSavedFilePath(String paramSavedFilePath) {
        savedFilePath = paramSavedFilePath;
    }
}

and just call:

MainController.setSavedFilePath("file path");
