java - Pass input from FXML text field to BCrypt.checkpassword -

-

i having first crack @ both fxml , bcrypt learning exercise.

i have 2 text fields in fxml , plan concatinate them in string compare hash bcrypt.

this example.fxml

<textfield fx:id="userid" layoutx="103.0" layouty="56.0" onaction="#loginpressed"/> <passwordfield fx:id="passwordfield" layoutx="103.0" layouty="111.0" onaction="#loginpressed"/>

this loginpage.java

private void loginpressed(actionevent event)   {      if (bcrypt.checkpw((unpwfield), passwordhash))         system.out.println("accepted");     else         system.out.println("denied");   }

i thought answer be

private string unpwfield = userid+passwordfield;

but doesnt work. (the operator + undefined argument type(s) javafx.scene.control.textfield, javafx.scene.control.textfield) why?

edit

i have tried following gives nullpointer

string unpwfield;     unpwfield = userid.gettext()+passwordfield.gettext();     if (bcrypt.checkpw(unpwfield, passwordhash))         system.out.println("it matches");     else         system.out.println(userid.gettext()+passwordfield.gettext());

turn out code correct. hadnt injected @fxml passwordfield
