New to Java

Hi, i have declare an arraylist

ArrayList list1 = new ArrayList();

Inside the arraylist, there are elements. Now, i wan to pass the elements in the java arraylist into javascript arrays but i encounter javascript errors.
This is how i code.

var arr1 = new Array();
<%
for ( int x =0; x<list1.size(); x++)
{
%>
	arr1[<%=x%>] = <%=(String)list1.get(x)%>; 
<%
}
%>

how do i solve this problem?

Thanks for the guidance in advance
