[JAVA] AIUTO - valori Object

[Wolvy23]

Salve a Tutti....
avrei bisogno di un aiuto in qunato non riesco a settare i valori per un Object destinato ad una JTable, come vedete dal seguente

........

	public Object[][] getRowData() {
		
		System.err.println("getIdElenco.length= "+getIdElenco().length);
		
		int lung = getIdElenco().length;

		Object[][] rowData = new Object[lung][];

		String[] id = getIdElenco(); //<--- PRIMA COLONNA VALORI
		String[] inout = getInoutElenco(); //<--- SECONDA COLONNA VALORI
		String[] importo = getImportoElenco(); //<--- TERZA COLONNA VALORI
		String[] data = getDataElenco(); //<--- QUARTA COLONNA VALORI
		String[] motivo = getMotivoElenco(); //<--- QUINTA COLONNA VALORI
		String[] categoria = getCategoriaElenco(); //<--- SESTA COLONNA VALORI
		String[] saldo = getSaldoElenco(); //<--- SETTIMA COLONNA VALORI
		
		for(int i=0; i<lung; i++) {
			rowData[i][] = {{id[i],inout[i],importo[i],data[i],motivo[i],categoria[i],saldo[i}};
		};
		return rowData;
	}

........

Ho provato anche così ma no va...

Object[][] rowData = {getIdElenco(),getInoutElenco(),getImportoElenco(),getDataElenco(),getMotivoElenco(),getCategoriaElenco(),getSaldoElenco()};

Sembra che sia riuscito a settare l'Object[][], ma mi da errore per la JTable.....

Classe della grafica della JTable.....

package grafica;
	 
	import java.awt.event.MouseAdapter;
	import java.awt.event.MouseEvent;
	import javax.swing.JTable;
	import javax.swing.JFrame;
	import javax.swing.JScrollPane;
	import javax.swing.table.TableModel;

import database.RegistroCassa;
	 
	public class RegistroGraf extends JFrame {
	    /**

		 */
		private static final long serialVersionUID = -7576128986849460543L;
		private JTable table;
	 
	    public RegistroGraf(RegistroCassa registro) {
	    	super("REGISTRO CASSA");
	 
	        Object[] columnHeaders = {"ID","OPERAZIONE","IMPORTO","DATA","MOTIVO","CATEGORIA","SALDO"};
	        Object[][] rowData = registro.getRowData();	        
	        
	        System.out.println(rowData.length);
	        System.out.println(rowData[2][2]);

	        this.table = new JTable(rowData, columnHeaders);
	        this.table.setFillsViewportHeight(true);

	        this.table.addMouseListener(
        		new MouseAdapter() { @Override
	                public void mouseClicked(MouseEvent event) {
	                    JTable table = (JTable)event.getSource();
	                    TableModel model = table.getModel();
	                    int nRow = model.getRowCount();
	                    int nCol = model.getColumnCount();

	                    System.out.println(nRow);
	                    System.out.println(nCol);                   
	                    
	                    for(int i = 0; i < nRow ; i++) {
	                        for(int j = 0; j < nCol; j++) {
	                            String colName = model.getColumnName(j);
	                            Object value = model.getValueAt(i, j);
	                            System.out.println(colName + "=" + value);
	                        }
	                        System.out.println();
	                    }
	                }
        		}
	        );
      
	        this.getContentPane().add(new JScrollPane(this.table));
	        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	        this.setSize(300, 300);
	        this.setLocationRelativeTo(null);
	    }
} //FINE CLASSE

.... e la classe (RegistroCassa) che passa i valori a rowData

package database;

import java.sql.ResultSet;
import java.sql.SQLException;

public class RegistroCassa {
	Database registro = new Database();
	private ResultSet dati;
	private String[] id, inout, importo, data, motivo, categoria, saldo;
	
	public RegistroCassa() {
		
	}
	
	public void setDati() throws SQLException {
		dati = registro.readDB("SELECT * FROM registro");
		String xId = "";
		String xInout = "";
		String xImporto = "";
		String xData = "";
		String xMotivo = "";
		String xCategoria = "";
		String xSaldo = "";
		try {
			while (dati.next()) {
				xId += dati.getString("ID")+"|";
				xInout += dati.getString("inOut")+"|";
				xImporto += dati.getString("importo")+"|";
				xData += dati.getString("data")+"|";
				xMotivo += dati.getString("motivo")+"|";
				xCategoria += dati.getString("categoria")+"|";
				xSaldo += dati.getString("saldo")+"|";
			}
		} catch (SQLException e) {
			System.err.println(e.getMessage());
		}
		setId(xId.split("\\|"));
		setInout(xInout.split("\\|"));
		setImporto(xImporto.split("\\|"));
		setData(xData.split("\\|"));
		setMotivo(xMotivo.split("\\|"));
		setCategoria(xCategoria.split("\\|"));
		setSaldo(xSaldo.split("\\|"));
		registro.readClose();
	}
	
	public Object[][] getRowData() {
		for (int i=0; i<getIdElenco().length; i++) {
			rowData[i] = {{id[i]},{inout[i]},{Importo[i]},{data[i]},{motivo[i]},{categoria[i]},{saldo[i]}};
		}*/
		
		Object[][] rowData = {getIdElenco(),getInoutElenco(),getImportoElenco(),getDataElenco(),getMotivoElenco(),
								getCategoriaElenco(),getSaldoElenco()};
		return rowData;
	}

............

e questo è l'errore che mi da senza visualizzare la JTable

Purtroppo non capisco dov'è l'errore!!!!
Grazie per l'attenzione, saluti

[Wolvy23]

Ho risolto assegnando i dati al JTable così

for(int i=0; i<rowData.length; i++) {
    model.addColumn(columnHeaders[i]);
}

for(int i=0; i<numRow; i++) {
     model.addRow(new Object[] {rowData[0][i],rowData[1][i],rowData[2][i],rowData[3][i],rowData[4][i],rowData[5][i],rowData[6][i]});	
}

Grazie lo stesso a Tutti.
