Question

我想将“HouseNumber，StreetName，Town，Postcode”的值（我的JPanel上的文本字段）添加到“地址”数组中，最好的方法是什么？谢谢

主要类

public class Main{
public static void main(String[] args){
JFrame frame = new JFrame("Burgess-Brown-Pearson Homes");
JPanel panel = new JPanel();
panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));
JLabel HouseNumberLabel = new JLabel("House Number");
JTextField HouseNumber = new JTextField("");
JLabel StreetNameLabel = new JLabel("Street Name");
JTextField StreetName = new JTextField("");
JLabel TownLabel = new JLabel("Town");
JTextField Town = new JTextField("");
JLabel PostCodeLabel = new JLabel("PostCode");
JTextField PostCode = new JTextField("");
JLabel BedsLabel = new JLabel("Number of Beds");
JTextField Beds = new JTextField("");
JLabel PriceLabel = new JLabel("Price");
JTextField Price = new JTextField("");
JLabel TypeLabel = new JLabel("Building Type");
JTextField Type = new JTextField("");
JButton Submit = new JButton("Submit");
frame.setSize(500,500);
panel.setSize(500,500);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(panel);
panel.add(HouseNumberLabel);
panel.add(HouseNumber);
panel.add(StreetNameLabel);
panel.add(StreetName);
panel.add(TownLabel);
panel.add(Town);
panel.add(PostCodeLabel);
panel.add(PostCode);
panel.add(BedsLabel);
panel.add(Beds);
panel.add(PriceLabel);
panel.add(Price);
panel.add(TypeLabel);
panel.add(Type);
panel.add(Submit);
frame.pack();
frame.show();
//Create new Person objects
Address p[] = new Address[3];
p[0] = new Address("27","Abbey View","Hexham","NE46 1EQ");
p[1] = new Address("15", "Chirdon Crescent", "Hexham", "NE46 1LE");
p[2] = new Address("6", "Causey Brae", "Hexham", "NE46 1DB");
Details c[] = new Details[3];
c[0] = new Details ("3", "175,000", "Terraced");
c[1] = new Details  ("6", "300,000", "Bungalow");
c[2] = new Details ("4", "250,000", "Detached");
 //Send some messages to the  objects
 c[0].setBeds("3 ");
 c[1].setBeds("6");
 c[2].setBeds("4");
 c[0].setPrice("175,000");
 c[1].setPrice("300,000");
 c[2].setPrice("250,000");
 c[0].setType("Terraced");
 c[1].setType("Bungalow");
 c[2].setType("Detached");
 //Set up the association
 p[0].ownsDetails(c[0]);
 p[1].ownsDetails(c[1]);
 p[2].ownsDetails(c[2]);

 System.exit(0);
 }
 }

地址类

    public final class Address{
    //Class properties
    private String HouseNumber, StreetName, Town, Postcode;
    //Allow this person to own a car
    private Details owns;

  //Constructor
  public Address(String aHouseNumber, String aStreetName, String Town, String Postcode)
  {
  setHouseNumber(aHouseNumber);
  setStreetName(aStreetName);
  setTown(Town);
  setPostcode(Postcode);
  }

  public Address(){
  }
  }

  //Add a house
  public void ownsDetails(Details owns){
  this.owns = owns;
  }
  //Set methods for properties
  public void setHouseNumber(String aName){
  HouseNumber = aName;
  }
  public void setStreetName(String aName){
  StreetName = aName;
  }
  public void setTown(String anName){
  Town = anName;
  }
  public void setPostcode (String anName){
  Postcode = anName;
  }
  //Get methods for properties
  public String getHouseNumber(){
  return HouseNumber;
  }
  public String setStreetName(){
  return StreetName;
  }
  public String setTown(){
  return Town;
  }
  public String setPostcode(){
  return Postcode;
  }

**详情类**

 public final class Details{
 //Class properties
 private String Type, Beds, Price;

 //Constructor
 public Details(String aType, String aBeds, String aPrice){
  setType(aType);
  setBeds(aBeds);
  setPrice(aPrice);
  }

  //Set methods for properties
  public void setType(String aType){
  Type = aType;
  }
  public void setBeds(String aBeds){
  Beds = aBeds;
  }
  public void setPrice(String aPrice){
  Price = aPrice;
  }
  //Get methods for properties
  public String getType(){
  return Type;

  public String getBeds() {

  public String getPrice(){

我真的不明白这个问题。您拥有所需的所有方法。无论如何，我会尝试给你一些提示。

首先，如果JTextField用于创建新地址，而不是更新其中一个，那么静态数组可能不是正确的选择。您应该使用ArrayList：

ArrayList<Address> p = new ArrayList<Address>();

然后只需从JTextFields中检索数据并构造另一个Address对象：

Address newAddress = new Address(HouseNumber.getText(),
                                 StreetName.getText(),
                                 Town.getText(),
                                 Postcode.getText());
p.add(newAddress);

这足以解决你的疑虑吗？

如何将输入到JPanel中的TextFields的值添加到数组中？
