Java使用setText具有int值 [英] Java have a int value using setText

问题描述

我正在尝试使用jTextField和setText方法设置一个int值.但是当然setText需要一个String.我如何解决这个问题?我将向您提供一段代码:

I'm trying to set an int value using jTextField and the setText method. But of course setText wants a String. How do I get round this? I'll give you a snippet of the code:

    private void setAllTextFields(FilmSystem e){
    getFilmNameTF().setText(e.getFilmName());
    lectureTF.setText(e.getLecture());
    ageTF.setText(e.getAge());
    priceTF.setText(e.getTicketCost());
    seatsTF.setText(e.getNoOfSeats());

seatsTF是一个jTextField，而getNoOfSeats是另一个类中的一个返回int值的方法.

seatsTF is a jTextField and getNoOfSeats is a method in another class that returns a int value.

再次感谢您回答这个问题.现在，我将如何获取int的值来做某事?

Thanks again for answering this question. Now how would I go about getting the value of the int to do something to do?

        public void buyTicket() {
    String newFilmName = filmNameTF.getText();
    String newLecture = lectureTF.getText();
    String newAge = ageTF.getText();
    String newPrice = priceTF.getText(); 
    int newSeats = seatsTF.

正如您所看到的代码，使用getText可以很容易地获得String值.然后，我可以将它们打印出来或与它们一起打印.我如何在seats int上做到这一点?再次感谢.

As you can see the code, the String values I can get easy with getText. I can then print them out or whatever with them. How can I do this with the seats int? Thanks again.

推荐答案

String#valueOf将您的int转换为String.

String.valueOf(e.getAge());将返回int参数的string表示形式.

String.valueOf(e.getAge()); will return the string representation of the int argument.

seatsTF.setText(String.valueOf(e.Age()));
