import java.util.ArrayList;
import javax.swing.table.AbstractTableModel;

/**

*/
abstract class myResultTableModel extends AbstractTableModel
{
public myResultTableModel(ResultSet myResultSet)
{
rs=myResultSet;
try {

rsmd=myResultSet.getMetaData();
} catch (SQLException ex) {
ex.printStackTrace();
}

}

public String getColumnName(int Col)
{
try {
return rsmd.getColumnName(Col+1);
} catch (SQLException ex) {
ex.printStackTrace();
return "Unknown";
}
}

public int getColumnCount()
{
try {
return rsmd.getColumnCount();
} catch (SQLException ex) {
ex.printStackTrace();
return 0;
}
}
public ResultSet getResultSet()
{
return rs;
}

private ResultSet rs;
private ResultSetMetaData rsmd;
}
public class CashingResultTableModel extends myResultTableModel
{

public CashingResultTableModel(ResultSet rs)
{
super(rs);
myData=new ArrayList();
int Cols=getColumnCount();
ResultSet myresult=getResultSet();
try {

while(myresult.next())
{
Object[] row=new Object[Cols];

for(int j=0;j<row.length;j++)
row[j]=myresult.getObject(j+1);

myData.add(row);
}

} catch (SQLException ex) {
ex.printStackTrace();
}

}

public int getRowCount()
{

return myData.size();

}

public Object getValueAt(int rowIndex, int columnIndex)
{
if(rowIndex<myData.size())
{
return ((Object[])myData.get(rowIndex))[columnIndex];
}
else
return null;
}

private ArrayList myData;

}
