need suggestion about "new JRadioButton"

[efm]

hello,
i'm new in java, and i need suggestion about things below:

which is better:

to use

private void try {
  radiobutton1.setSelected(true);
  radiobutton2.setSelected(false);
  radiobutton3.setSelected(false);
}

or this one:

private void setSelectedRadioButtons(JRadioButton[] rb, boolean[] b) {
  for (int i=0; i<=rb.length; i++) {
    rb[i].setSelected(b[i]);
  }
}

private void try {
  setSelectedRadioButtons( 
    new JRadioButton[] { radiobutton1, radiobutton2, radiobutton3 },
    new boolean[] { true, false, false }
  }
}

currently, i'm using the latter in my program, but i'm afraid that it takes lots of memory or
it's a "not suggested" line of code.

if the latter is ok, then i will use it for other components and properties

thank you
