Java Jframe looping getText and getInt in checkboxes

can someone help me for lopping this code?

 if(box1.isSelected()){ N = box1.getText();
    P = Float.valueOf(price1.getText());
    S = Integer.parseInt(spin1.getValue().toString());
    PT = S*P;
    selected();
 }

I have a total of 60 checkboxes I use JFrame and every every box has the variable name of box1 to box60 i just want to minimize my code Thanks In Advanced
