How to declare an expandable 2-dim Array

Question

Hi,
How do I declare a 2-dim array that is can expandable with additional data?

Answer 1

Look at this example (Catching the ideas of the other guis:
e.g. create a Class Object which represents a Row
class Row {
ArrayList list = new ArrayList(10); //ten columns
public Object getObject(int x) {
list.get(x);
public void setObject(Object o, int x) {
list.add(x, o);
Create an Table Object which is able to add your Rows-Objects
class Table {
ArrayList rows = new ArrayList();
public void addRow(Row row) {
rows.add(row);
public Row getRow(int x) {
return (Row) rows.get(x);
public int getNrOfRows() {
return rows.size();
after this, you can fill your Objects like this
Row row = new Row();
row.setObject(0, "James");
row.setObject(1, "Kirk");
row.setObject(2, "Captain);
Table table = new Table():
table.add(row);
Hope it helps a little bit
