这是我前一天问过的一个问题的后续问题，我一直试图调试代码没有成功，但基本上应用程序应该允许用户在选择后选择要导入或查看的CSV该文件只能在JTable中查看Csv的内容。目前我可以查看csv中的数据，但它没有像JIB那样在Jtable中显示。这是下面程序的代码，除了netbeans抛出我。
public class Asist_payment_import_v1 extends JPanel implements ActionListener{
private final JTable Table;
public Asist_payment_import_v1(){
super(new BorderLayout(3,3));
this.Table = new JTable(new MiModel());
this.Table.setPreferredScrollableViewportSize(new Dimension(700,70));
this.Table.setFillsViewportHeight(true);
JPanel ButtonOpen = new JPanel(new FlowLayout(FlowLayout.CENTER));
//the below utton will be used to upload csv data to Database, the action listener should connect to the db, and pass data into the Db.
//JPanel ButtonUpload = new JPanel(new FlowLayout(FlowLayout.LEFT));
JButton open_file = new JButton("Open");
JButton save_file = new JButton("Save");
ButtonOpen.add(open_file);
add(ButtonOpen, BorderLayout.SOUTH);
open_file.addActionListener(this);
save_file.addActionListener(this);
//create scrollPane to this Panel
JScrollPane scrollpane = new JScrollPane(Table);
//add the scroll pane to this pane
add(scrollpane,BorderLayout.CENTER);
//add Border
setBorder(new EmptyBorder(5,5,5,5));
}
public void actionPerformed(ActionEvent Event)
{
JFileChooser file_chooser = new JFileChooser();
boolean pressed = true;
if(pressed)
{
int ReturnVal = file_chooser.showOpenDialog(null);
CSVFile Rd = new CSVFile();
MiModel NewModel = new MiModel();
this.Table.setModel(NewModel);// to set the Table model
File DataFile = file_chooser.getSelectedFile();
ArrayList<String[]> rs2 = Rd.ReadCSVFile(DataFile);
NewModel.AddCSVData(rs2);
System.out.println("Rows: " +NewModel.getRowCount());
System.out.println("Cols: " +NewModel.getColumnCount());
}
}

OneRow = st.split(",");
Rs.add(OneRow);
System.out.println(Arrays.toString(OneRow));
}
}//end try

System.out.println("File not Found: "+errmsg);

这是netbeans输出面板上显示的结果的一部分，而不是JTable：

我遇到了这个问题的解决方案，我对我的CSV方法进行了修改，读取了csv数据..这里是所做的更改
public class CSVFile
{
private ArrayList<String[]> arrLs = new ArrayList<>();
private Object OneRow;
public ArrayList<String[]> ReadCSVFile(File DataFile)
{
try
{
//BufferedReader to Read through CSV Contents
BufferedReader reader = new BufferedReader (new FileReader(DataFile));
String line;
// while loop to read through the data, while bufferedreader is not null-do ....
while(reader.readLine()!= null)
{
try
{
line = reader.readLine();
if(line != null)
{
String[] array = line.split(",");
for(String result:array)
{
//System.out.println(OneRow[2]+");
System.out.println(result);
}
}
}
catch(Exception ex)
{
ex.printStackTrace();
}
finally
{
if(reader == null)
{
reader.close();
}
}
//if statement needed in the case the
//Selected CSV has more than the required number of ColumnHeaders
//and the BufferedReader needs to skip the first Row, as this is the
//columnHeaders and they cannot be included again
String read = reader.readLine();//bufferedreader string variable
OneRow = read.split(",");
arrLs.add((String[]) OneRow);
// System.out.println(Arrays.toString(OneRow));
}//end try
catch(Exception ex)
{
String errmsg = ex.getMessage();
//System.out.println("File not Found: "+errmsg);
} // end exception handling
return (ArrayList<String[]>) arrLs;
} //End of ArrayList_readCSVFile class
} //End of CSVFile class
}
这使我能够查看JTable中的csv数据，这是这里的主要问题
