我想为faculty类(facultyapp的子类)创建一个对象,在这里我可以输入一些值
错误:不兼容的类型:字符串不能转换为textfield faculty=new faculty(“,”“,”“);

FXMLDocumentController

公共类fxmldocumentcontroller实现可初始化{

private Label label;
@FXML
private TextField employeeName;
@FXML
private TextField employeeTitle;
@FXML
private TextField emailAddress;
@FXML
private Button SaveButton;

@Override
public void initialize(URL url, ResourceBundle rb) {
    // TODO
}    
public void setNAME(TextField employeeName) {
     employeeName.getText();    
}
public void setADDRESS(TextField emailAddress) {
    emailAddress.getText();
}
public void setTITLE(TextField employeeTitle) {

employeeTitle.getText();
}

@FXML
private void saveInfo(ActionEvent event) {
    Faculty faculty = new Faculty(" ", " ", " ");
    String textField = new TextField().toString();
    faculty.setNAME(employeeName);
    faculty.setADDRESS(emailAddress);
    faculty.setTITLE(employeeTitle);

    String message = "YOUR INPUT HAS BEEN SAVED";
    Alert a = new Alert(AlertType.INFORMATION); 
    a.setContentText(message +"\nEmployee Name: "+employeeName +"\nEmployee Title: "+ employeeTitle +"\nEmail Address: " + emailAddress);
    a.show();  

}

}

childClass from MainClass

公共类教员扩展facultyapp{私有文本字段标题、姓名、地址;

public Faculty (TextField employeeName, TextField emailAddress, TextField employeeTitle){
    title = employeeTitle;
    name = employeeName;
    address = emailAddress;
}

public void setNAME(TextField employeeName) {
    name = employeeName;
}
public TextField  getNAME(){
    return name;
}
public void setADDRESS(TextField emailAddress) {
    address = emailAddress;
}
public TextField getADDRESS(){
    return address;
}

public void setTITLE(TextField employeeTitle) {
    title = employeeTitle;
}
public TextField getTITLE(){
    return title;
}

}

你的 Faculty 类的构造函数需要3个类型为 TextField ,但你想通过3级 String 物体。
既然您使用的是setter,为什么不删除当前的构造函数并创建一个新的 Faculty 通过使用默认构造函数?
所以把这个从 Faculty 班级:

public Faculty (TextField employeeName, TextField emailAddress, TextField employeeTitle){
    title = employeeTitle;
    name = employeeName;
    address = emailAddress;
}

而且在 FXMLDocumentController 改变

Faculty faculty = new Faculty(" ", " ", " ");

进入之内

Faculty faculty = new Faculty();
