Java：JTable中的控制台输出

Question

程序应在中列出卷JTable。

例如：我从vollist.java类获得此输出。

while (volumeIter.hasNext()) {
    volume = volumeIter.next();
    System.out.println(volume.getName());
}

控制台输出：

vol1
vol2
vol3
...

如何在我的控制台中获得此控制台输出JTable。

table = new JTable();
table.setModel(new DefaultTableModel(
    new Object[][] {
        {null, vollist.volname(null), null, null, null},
        {null, vollist.volname(null), null, null, null},
        {null, vollist.volname(null), null, null, null},
    },
    new String[] {
        "Nr:", "Volume Name", "TotalSize [MB]", "Used [MB]", "Status"
    }
));

那只会显示row1-> vol1 row2-> vol1 ............如何获得类似于控制台row1-> vol1 row2->
vol2的输出（计数）

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);
