Array of radio buttons

Question

Hi everybody,
i have to implement an interface where the number of radio buttons depends on the elements of an String [ ], so i am trying to implement it as an array (I do not know any other method). But the prblem i�m getting back some mistakes.
String[] chain= new String [3];
chain[0]= "uno";
chain[1]= "dos";
chain[2]= "tres";
//Add everything to a container.
Box box = Box.createVerticalBox();
box.add(label1);
box.add(Box.createVerticalStrut(isotopos.length));
for (int i=0;i< chain.length;i++)
JRadioButton[ ] rb = new JRadioButton();
rb.setText(isotopos[i]);
rb[i].addActionListener(this);
rb[i].setSelected(true);
bg1.add(rb[i]);
anyone knows how to do it? Thanks

JRadioButton[ ] rb = new JRadioButton();
That line is invalid: you can't assign a JRadioButton to a type JRadioButton[].
In any case, you want to assign your array outside the loop if you want to assign its elements inside.
And besides that, you don't even need to create the array. Just create the buttons and add them to the box, unless you need to retain references to them (in which case a local array is probably useless anyway).
And don't forget radio buttons need to be grouped.
