定义并实现您的TableModel（在这种情况下，扩展AbstractTableModel）
这更广泛，但是是OOP强类型。
class VoluMetableModel extends AbstractTableModel {
private String[] columnNames = {"Nr:", "Volume Name", "TotalSize [MB]", "Used [MB]", "Status"};
private ArrayList<Volume> volumes;
public VoluMetableModel(ArrayList<Volume> volumes) {
this.volumes = volumes;
}
public VoluMetableModel() {
volumes = new ArrayList<Volume>();
}
public void addVolume(Volume volume) {
volumes.add(volume);
fireTableRowsInserted(volumes.size()-1, volumes.size()-1);
}
public int getColumnCount() {
return columnNames.length;
}
public int getRowCount() {
return volumes.size();
}
public String getColumnName(int col) {
return columnNames[col];
}
public Object getValueAt(int row, int col) {
Volume volume = volumes.get(row);
switch (col) {
case 0: return volume.number;
case 1: return volume.name;
case 2: return volume.totalSize;
case 3: return volume.usedSize;
case 4: return volume.status;
default: return null;
}
}
public Class getColumnClass(int col) {
return String.class;
//or just as example
switch (col) {
case 0: return Integer.class;
case 1: return String.class;
case 2: return Integer.class;
case 3: return Integer.class;
case 4: return String.class;
default: return String.class;
}
}
}
并将其指定为表的TableModel
//if you have the Volume ArrayList
VoluMetableModel myTableModel = new VoluMetableModel(volumesArrayList);
//if you dont have the Volume ArrayList
VoluMetableModel myTableModel = new VoluMetableModel();
myTableModel.addVolume(volume);
JTable table = new JTable(myTableModel);
