Strings as an ArrayList and use in another class

I'd like to get my values in an array. Later I'd like to use the array in another class. How can this be done? 

table.addMouseListener(new MouseAdapter() {
            public void mouseClicked(MouseEvent e) {
                if (e.getClickCount() == 1) {
                    JTable target = (JTable) e.getSource();
                    int row = target.getSelectedRow();
                    int column = target.getSelectedColumn();

                    row = table.convertRowIndexToModel(row);
                    String val1 = (String) table.getModel().getValueAt(row, 0);
                    String val2 = (String) table.getModel().getValueAt(row, 1);
                    String val3 = (String) table.getModel().getValueAt(row, 2);
                    String val4 = (String) table.getModel().getValueAt(row, 3);
                    String val5 = (String) table.getModel().getValueAt(row, 4);

                    System.out.println(val1 + " " + val2 + " " + val3 + " " + val4 + " " + val5);
                }
            }
        });

Another way, with collections, they normally easier to work with:

List<String> values = new ArrayList<>();
values.add((String) table.getModel().getValueAt(row, 0))
..
..
values.add((String) table.getModel().getValueAt(row, 4););

Instantiate a new array with the size of the values you are going to add. If you do not know the size you should look into using ArrayList

String[] arr = new String[5];

Add values to the array. You could probably put this in a loop so the code will be less verbose.

String val1 = (String) table.getModel().getValueAt(row, 0);
arr[0] = val1;

String val2 = (String) table.getModel().getValueAt(row, 1);
arr[1] = val2;

...

then return the array

return arr;
