Hi,
My program is something like this:

<script type="text/javascript">
function clicked2()
var x2;
for (var i = 0; i < form1.radio.length; i++)
if (form1.radio.checked)
x2=(form1.radio[i].value );
document.form2.hiddenTextBox.value = x2;
</script>
<%int i=0;
for(int l=1;l<=(Ress.size()/4);l++){ //Ress is my vector of results
%>
<tr>
<td width="10%">
<form method="get" name="form1" action="Update.jsp">
<fieldset>
<input type="radio" name="radio" value="<%=l%>">
</fieldset>
<input type=submit name="submit" value="Update" onclick="clicked2()">
</form>

<% int y2 =0;
if(request.getParameter("submit") != null){
y2 =Integer.parseInt(request.getParameter("hiddenTextBox"));

"private static double area (int radius, final double pi)"
final double pi? as the method parameter? ROFLHAHAHAHAHAHAHAHAHAHAHA
That made my day.
As for your question, make range_1 a global variable, in other words, declare it outside your main method
Something like
public class gary{
int range_1;
public static void main (String afgfg[]){
range_1=//something;
private static double area (int radius)
radius = range_1
return radius * radius * 3.14
