我如何跨两个类使用JTextField。例如,从一个类中获取一个整数值,并将其显示在另一类中的textField中。从jFrame到JFrame

最佳答案

然后嵌套,这样就得到了一个类,该类获取实际显示该整数值的整数值,例如:

//Note: this is only a rough representation of the concept
//      what I am trying to get across, it wouldn't really
//      work like this

class Displayer{
    ValueGetter valueGetter;
    JTextField textField;

    public Displayer(){
        valueGetter = new ValueGetter();
    }

    public void display(){

        int value = valueGetter.workOutValue();

        textField.setText(value);
    }
}
