装载ArrayList的数据转换成的JTable [英] Load arrayList data into JTable

问题描述

我想从一个名为方法设置的项目 FootballClub ，到目前为止，它的罚款。
但后来我从它创建了一个ArrayList和我有点不能找到一种方法来存储这些信息到一个JTable。
问题是，我不能找到一种方法来设置行的固定数量

下面是我的code：

类StartLeague：

 进口的javax.swing *。
导入的javax.swing.table *。
进口java.awt中的*。公共类startLeague实现LeagueManager {//设置框架和其他组件出现公共startLeague（）{
    JButton的createTeam =的新的JButton（创建组）;
    JButton的deleteTeam =的新的JButton（删除小组）;    JFrame的帧=新的JFrame（premier联赛系统）;
    的JPanel面板=新JPanel（）;
    frame.setSize（1280，800）;
    frame.setVisible（真）;
    frame.add（面板）;
    frame.setDefaultCloseOperation（JFrame.EXIT_ON_CLOSE）;
    串COL [] = {正，队，P，W，L，D，MP，GF，GA，GD};    panel.setLayout（新的GridLayout（20，20））;
    panel.add（createTeam）;
    panel.add（deleteTeam）;
    panel.add（新的JLabel（））;
    //的JLabel以填补空间
    }
    }
 

足球俱乐部类别：

 进口的java.util.ArrayList; 公共类FootballClub扩展体育俱乐部{   FootballClub（INT位置，字符串名称，诠释点，诠释获胜，诠释连败，INT平局，INT totalMatches，诠释goalF，诠释goalA，诠释概略性的东西）{
   this.position =位置;
   this.name =名称;
   this.points =分;
   this.wins =胜;
   this.defeats =失败;
   this.draws =绘制;
   this.totalMatches = totalMatches;
   this.goalF = goalF;
   this.goalA = goalA;
   this.goalD =概略性的东西;   }
 

在体育俱乐部类（abstract）：

 抽象类体育俱乐部{
INT位置;
字符串名称;
INT点;
INT胜;
诠释失败;
INT绘制;
INT totalMatches;
INT goalF;
诠释goalA;
INT概略性的东西;}
 

最后，LeagueManager，这是一个接口

 进口的java.util.ArrayList;
公共接口LeagueManager {
ArrayList的＆LT; FootballClub＆GT; originalLeagueTable =新的ArrayList＆LT; FootballClub＆GT;（）;
FootballClub阿森纳=新FootballClub（1，阿森纳，35，11，2，2，15，30，11，19）;
FootballClub利物浦=新FootballClub（2，利物浦，30，9,3，3，15，34，18，16）;
FootballClub切尔西=新FootballClub（3，切尔西，30，9,2，2，15，30，11，19）;
FootballClub mCity =新FootballClub（4，人之城，29日，9，2，4，15，41，15，26）;
FootballClub埃弗顿=新FootballClub（5，埃弗顿，28，7,1，7，15，23，14，9）;
FootballClub TOT =新FootballClub（6，热刺，27，8，4，3，15，15，16，-1）;
FootballClub纽卡斯尔=新FootballClub（7，纽卡斯尔，26日，8，5，2，15，20，21，-1）;
FootballClub南=新FootballClub（8南安普敦，23，6，4，5，15，19，14，5）;}
 

有人可以帮帮我吗？
我想，努力了好几天。
谢谢你。

解决方案

  

的问题是，我不能找到一种方法来设置行的固定数量的的

您不必设置的行数。使用的TableModel 。 A 的DefaultTableModel 尤其

 字符串COL [] = {POS，团队，P，W，L，D，MP，GF GA，GD};DefaultTableModel方面的TableModel =新的DefaultTableModel（COL，0）;
                                            // 0的参数是行数。JTable的表=新的JTable（TableModel的）;
 

然后，您可以用行添加到的TableModel 的对象[]

 对象[] = OBJ文件{1，阿森纳，35，11，2，2，15，30，11，19};tableModel.addRow（OBJ文件）;
 

您可以循环添加你的对象[]数组。

注：JTable中目前不允许实例与输入数据作为的ArrayList 。它必须是一个矢量或数组。

请参阅 JTable中和<一个href=\"http://docs.oracle.com/javase/7/docs/api/javax/swing/table/DefaultTableModel.html\">DefaultTableModel.此外，如何使用JTable的教程

  

的我从它创建了一个ArrayList和我有点不能找到一种方法来存储这些信息到JTable中。的

您可以做这样的事情添加数据

 的ArrayList＆LT; FootballClub＆GT; originalLeagueList =新的ArrayList＆LT; FootballClub＆GT;（）;originalLeagueList.add（新FootballClub（1，阿森纳，35，11，2，2，15，30，11，19））;
originalLeagueList.add（新FootballClub（2，利物浦，30，9,3，3，15，34，18，16））;
originalLeagueList.add（新FootballClub（3，切尔西，30，9,2，2，15，30，11，19））;
originalLeagueList.add（新FootballClub（4，人之城，29日，9，2，4，15，41，15，26））;
originalLeagueList.add（新FootballClub（5，埃弗顿，28，7,1，7，15，23，14，9））;
originalLeagueList.add（新FootballClub（6，热刺，27，8,4，3，15，15，16，-1））;
originalLeagueList.add（新FootballClub（7，新城疫，26，8,5，2，15，20，21，-1））;
originalLeagueList.add（新FootballClub（8南安普敦，23，6，4，5，15，19，14，5））;的for（int i = 0; I＆LT; originalLeagueList.size（）;我++）{
   INT位置= originalLeagueList.get（I）.getPosition（）;
   字符串名称= originalLeagueList.get（I）.getName（）;
   INT点= originalLeagueList.get（I）.getPoinst（）;
   INT胜= originalLeagueList.get（I）.getWins（）;
   INT击败= originalLeagueList.get（I）.getDefeats（）;
   INT平= originalLeagueList.get（I）.getDraws（）;
   INT totalMatches = originalLeagueList.get（I）.getTotalMathces（）;
   INT goalF = originalLeagueList.get（I）.getGoalF（）;
   INT goalA = originalLeagueList.get（I）.getGoalA（）;
   在ttgoalD = originalLeagueList.get（ⅰ）.getTtgoalD（）;   [对象]数据= {位置，名称，分，胜，负，平，
                               totalMatches，goalF，goalA，ttgoalD};   tableModel.add（数据）;}
 

I'm trying to set items from a method called FootballClub and so far it's fine. but then I created an arrayList from it and I somehow can't find a way to store this information into a JTable. The problem is that i cant find a way to set a fixed number of rows

Here is my code:

Class StartLeague:

import javax.swing.*;
import javax.swing.table.*;
import java.awt.*;

public class startLeague implements LeagueManager{

//setting the frame and other components to appear

public startLeague(){
    JButton createTeam = new JButton("Create Team");
    JButton deleteTeam = new JButton("Delete Team");

    JFrame frame = new JFrame("Premier League System");
    JPanel panel = new JPanel();
    frame.setSize(1280, 800);
    frame.setVisible(true);
    frame.add(panel);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    String col[] = {"Pos","Team","P", "W", "L", "D", "MP", "GF", "GA", "GD"};

    panel.setLayout(new GridLayout(20, 20));
    panel.add(createTeam);
    panel.add(deleteTeam);
    panel.add(new JLabel(""));
    //JLabels to fill the space
    }
    }

FootBall Club Class:

import java.util.ArrayList;



 public class FootballClub extends SportsClub{





   FootballClub(int position, String name, int points, int wins, int defeats, int draws, int totalMatches, int goalF, int goalA, int goalD){
   this.position = position;
   this.name = name;
   this.points = points;
   this.wins = wins;
   this.defeats = defeats;
   this.draws = draws;
   this.totalMatches = totalMatches;
   this.goalF = goalF;
   this.goalA = goalA;
   this.goalD = goalD;

   }

The SportsClub Class(abstract):

abstract class SportsClub {
int position;
String name;
int points;
int wins;
int defeats;
int draws;
int totalMatches;
int goalF;
int goalA;
int goalD;

}

And finally, LeagueManager, which is an interface:

import java.util.ArrayList;


public interface LeagueManager {
ArrayList<FootballClub> originalLeagueTable = new ArrayList<FootballClub>();
FootballClub arsenal = new FootballClub(1, "Arsenal", 35, 11, 2, 2, 15, 30, 11, 19);
FootballClub liverpool = new FootballClub(2, "Liverpool", 30, 9, 3, 3, 15, 34, 18, 16);
FootballClub chelsea = new FootballClub(3, "Chelsea", 30, 9, 2, 2, 15, 30, 11, 19);
FootballClub mCity = new FootballClub(4, "Man City", 29, 9, 2, 4, 15, 41, 15, 26);
FootballClub everton = new FootballClub(5, "Everton", 28, 7, 1, 7, 15, 23, 14, 9);
FootballClub tot = new FootballClub(6, "Tottenham", 27, 8, 4, 3, 15, 15, 16, -1);
FootballClub newcastle = new FootballClub(7, "Newcastle", 26, 8, 5, 2, 15, 20, 21, -1);
FootballClub south = new FootballClub(8, "Southampton", 23, 6, 4, 5, 15, 19, 14, 5);

}

Can somebody please help me? I've trying and trying for days. Thank you.

"The problem is that i cant find a way to set a fixed number of rows"

You don't need to set the number of rows. Use a TableModel. A DefaultTableModel in particular.

String col[] = {"Pos","Team","P", "W", "L", "D", "MP", "GF", "GA", "GD"};

DefaultTableModel tableModel = new DefaultTableModel(col, 0);
                                            // The 0 argument is number rows.

JTable table = new JTable(tableModel);

Then you can add rows to the tableModel with an Object[]

Object[] objs = {1, "Arsenal", 35, 11, 2, 2, 15, 30, 11, 19};

tableModel.addRow(objs);

You can loop to add your Object[] arrays.

Note: JTable does not currently allow instantiation with the input data as an ArrayList. It must be a Vector or an array.

See JTable and DefaultTableModel. Also, How to Use JTable tutorial

"I created an arrayList from it and I somehow can't find a way to store this information into a JTable."

You can do something like this to add the data

ArrayList<FootballClub> originalLeagueList = new ArrayList<FootballClub>();

originalLeagueList.add(new FootballClub(1, "Arsenal", 35, 11, 2, 2, 15, 30, 11, 19));
originalLeagueList.add(new FootballClub(2, "Liverpool", 30, 9, 3, 3, 15, 34, 18, 16));
originalLeagueList.add(new FootballClub(3, "Chelsea", 30, 9, 2, 2, 15, 30, 11, 19));
originalLeagueList.add(new FootballClub(4, "Man City", 29, 9, 2, 4, 15, 41, 15, 26));
originalLeagueList.add(new FootballClub(5, "Everton", 28, 7, 1, 7, 15, 23, 14, 9));
originalLeagueList.add(new FootballClub(6, "Tottenham", 27, 8, 4, 3, 15, 15, 16, -1));
originalLeagueList.add(new FootballClub(7, "Newcastle", 26, 8, 5, 2, 15, 20, 21, -1));
originalLeagueList.add(new FootballClub(8, "Southampton", 23, 6, 4, 5, 15, 19, 14, 5));

for (int i = 0; i < originalLeagueList.size(); i++){
   int position = originalLeagueList.get(i).getPosition();
   String name = originalLeagueList.get(i).getName();
   int points = originalLeagueList.get(i).getPoinst();
   int wins = originalLeagueList.get(i).getWins();
   int defeats = originalLeagueList.get(i).getDefeats();
   int draws = originalLeagueList.get(i).getDraws();
   int totalMatches = originalLeagueList.get(i).getTotalMathces();
   int goalF = originalLeagueList.get(i).getGoalF();
   int goalA = originalLeagueList.get(i).getGoalA();
   in ttgoalD = originalLeagueList.get(i).getTtgoalD();

   Object[] data = {position, name, points, wins, defeats, draws, 
                               totalMatches, goalF, goalA, ttgoalD};

   tableModel.add(data);

}
