我在打印（fname1，lname1）中扫描的名字和姓氏时遇到问题。我必须创建6个对象，这些是我似乎无法开始的两个对象。此外，如果我输入除“是”或“y”之外的任何内容，它将不会循环回到我在片段上方插入的单选按钮。我该如何解决这个问题？
这是在输出窗口中输出的内容：
[,0,0,0x0,invalid,layout=java.awt.FlowLayout,alignmentX=0.0,alignmentY=0.0,border=,flags=9,maximumSize=,minimumSize=,preferredSize=java.awt.Dimension[width=350,height=200]]
public class Cabin_Selector
{
public static void main(String[] args)
{
JFrame cabin_selection = new JFrame("Select Your Cabin"); //Prompts the user
cabin_selection.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //Close the Frame when exiting
Project2_JoshuaLucas selection = new Project2_JoshuaLucas("", "", "", "", "", "", "", 0.00); //Call the constructor for the Project2_JoshuaLucas class
cabin_selection.getContentPane().add(selection); //put the object in the current pane of the jframe
cabin_selection.pack(); //size the frame
cabin_selection.setVisible(true); //make the frame visible
} //end main method
} //end class
if (source == cabin1)

info1 = scan_in.nextLine();
info1 = info1.toLowerCase();
if ( info1.equals ("yes") || info1.equals ("y"))
{
continues=true;
System.out.println("Please enter the number of people in your cabin (*Maximum number of people is 2*)");

答案 0 :(得分：0)
您显示一个Swing组件返回的toString()方法 - 可能是JPanel，因为它使用FlowLayout，解决方案是：
System.out.println(...)来电，public String toString()方法覆盖，因此打印出来的内容是有道理的。你问：
什么是模型对象？
如果您正在创建一个飞机GUI，您可能需要创建几个类，一些GUI组件类，其他非类。模型类可以包括：
这些模型类将包含有关自己的信息，例如乘客将有一个名字，也许是一个年龄，一个乘客号码...飞机将拥有一流的AirplaneSeats和同样的教练。 AirplaneSeat将有一个布尔占用的字段，也许是一个Passenger字段来告诉谁占用了什么座位。但是这些类都不包含GUI组件代码，没有一个会扩展JPanel或JFrame等。
然后你可能会有扩展GUI组件或包含它们的视图类，它们将显示上面模型类的状态。您试图打印出视图类的toString（），它不会覆盖toString（）方法。
侧面建议：您似乎正在尝试将Swing GUI程序与控制台程序混合使用，而您不会想要这样做。相反，您应该在GUI中进行所有用户交互和输出，而不是在控制台中，除非是为了简单的调试目的，但仅此而已。
