JTable and loading 350 Mb file

Question

Hi guys, can you help me,
What is the best way to load and to handle such a big amount of data? I want to visualize them in a Table, let say JTable. Can someone give me a link with a control or piece of code that handles the data in parts?

Answer 1

this is my custom table:
class MyTableModel extends javax.swing.table.AbstractTableModel {
protected java.util.Vector data;
protected java.lang.Object data2[][];
protected String[] columnNames = {"Hello", "Johnny, "World"};
public MyTableModel() {
super();
data = new java.util.Vector();
public int getColumnCount() {
return columnNames.length;
public int getRowCount()
return data.size();
public void clear() {
data.removeAllElements();
fireTableDataChanged();
public void removeRow( int i ) {
data.removeElementAt(i);
fireTableRowsDeleted(i,i);
public String getColumnName(int col) {
return columnNames[col];
public Object getValueAt(int row, int col) {
Object[] o = (Object[])data.elementAt(row);
return o[col];
public Class getColumnClass(int c) {
return getValueAt(0, c).getClass();
public boolean isCellEditable(int row, int col) {
return col > 0 && row < getRowCount()-1;
/*public void setValueAt(Object value, int row, int col) {
data2[row][col] = value;
if (isCellEditable(row, col))
fireTableCellUpdated(row, col);
public void addRow(Object o[]) {
for( int i=0; i<o.length; i++ ) {
if( o[i] == null ) {
o[i] = new String();
data.addElement(o);
// entry added to the end, so fire an event to notify the table
// to update itself
fireTableRowsInserted(data.size()-1,data.size()-1);
}
