[FIXED] JavaFX: Read data from text file and paste it to the right place

Issue

I have a javafx homework at school

enter image description here

I was able to save the data as requested

enter image description here

My question is how can I read the data from the Text File so that all the data is back in the right place

enter image description here

Integer cb_years_v;
            String cb_manuf_v,smb_type_v,tg_v,cb_extras_v,lv_size_v,tf_vend_user_v,tf_vend_name_v,pf_pass_v,ta_other_v,price_value_v;
            
            cb_manuf_v = cb_manuf.getValue(); //ComboBox
            smb_type_v=ch_type.getText(); //SplitMenuButton
            tg_v = tg.getSelectedToggle().toString(); //ToggleGroup
            cb_extras_v = cb_extras.getValue(); //ComboBox
            cb_years_v = cb_years.getValue(); //ComboBox
            lv_size_v = lv_size.getSelectionModel().getSelectedItem().toString(); //ListView
            tf_vend_name_v = tf_vend_name.getText(); //TextField
            tf_vend_user_v = tf_vend_user.getText(); //TextField
            pf_pass_v = pf_pass.getText(); //PasswordField
            ta_other_v = ta_other.getText(); //TextArea
            price_value_v = price_value.getText(); //Label
            
            FileChooser chooser = new FileChooser();
            chooser.setTitle("Choose location To Save Report");;
            File selectedFile = null;
            while(selectedFile== null){
                selectedFile = chooser.showSaveDialog(null);
            }
            File file2 = null;
            file2 = selectedFile;
            PrintWriter outFile = null;
            try {
                outFile = new PrintWriter(file2);
            } catch (FileNotFoundException e2) {
                e2.printStackTrace();
            }
            outFile.println("Manufacturer = " + cb_manuf_v);
            outFile.println("Type = "+smb_type_v);  
            outFile.println("Color = " +tg_v);    
            outFile.println("Extras = " + cb_extras_v);
            outFile.println("Year = " + cb_years_v);
            outFile.println("Size = " + lv_size_v);
            outFile.println("Vendor Name = " + tf_vend_name_v);
            outFile.println("Vendor User = " + tf_vend_user_v);
            outFile.println("Password = " + pf_pass_v);
            outFile.println("Other = " + ta_other_v);
            outFile.println("Price = " + price_value_v);
            
            outFile.close();

Thank you for your help!

Solution

Here is another way you could do it. Instead of using Scanner, you could use Files.readAllLines. From there, you can use the line index as the control in a Switch-Statement or if a line contains the info you need to extract using an If-Statement. This example does not show the Switch-Statement version. It only shows the If-Statement version. I did not test this code so there may be errors.

try {
    File selectedFile = new File("");
    List < String > lines = Files.readAllLines(selectedFile.toPath());
    for (String line: lines) {
        if (line.contains("Manufacturer")) {
            cb_manuf.setValue(line.split("=")[1].strip());
        } else if (line.contains("Type")) {
            smb_type.setText(line.split("=")[1].strip());
        } else if (line.contains("Color")) {
            ...
        } else if (line.contains("Extras")) {
            ...
        } else if (line.contains("Year")) {
            ...
        } else if (line.contains("Size")) {
            ...
        } else if (line.contains("Vendor Name")) {
            ...
        } else if (line.contains("Vendor User")) {
            ...
        } else if (line.contains("Password")) {
            ...
        } else if (line.contains("Other")) {

        } else if (line.contains("Price")) {
            ...
        }
    }
} catch (IOException ex) {
    ex.printStackTrace();
}
