Load arrayList data into JTable
"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);
}
You probably need to use a TableModel
(Oracle's tutorial here)
How implements your own TableModel
public class FootballClubTableModel extends AbstractTableModel {
private List<FootballClub> clubs ;
private String[] columns ;
public FootBallClubTableModel(List<FootballClub> aClubList){
super();
clubs = aClubList ;
columns = new String[]{"Pos","Team","P", "W", "L", "D", "MP", "GF", "GA", "GD"};
}
// Number of column of your table
public int getColumnCount() {
return columns.length ;
}
// Number of row of your table
public int getRowsCount() {
return clubs.size();
}
// The object to render in a cell
public Object getValueAt(int row, int col) {
FootballClub club = clubs.get(row);
switch(col) {
case 0: return club.getPosition();
// to complete here...
default: return null;
}
}
// Optional, the name of your column
public String getColumnName(int col) {
return columns[col] ;
}
}
You maybe need to override anothers methods of TableModel
, depends on what you want to do, but here is the essential methods to understand and implements :)
Use it like this
List<FootballClub> clubs = getFootballClub();
TableModel model = new FootballClubTableModel(clubs);
JTable table = new JTable(model);
Hope it help !
