required java.util.ArrayList,found java.lang.Object : I do not understand the reason for this error

Question

Following are some snippets from a jsp page:

<%! ArrayList songList = new ArrayList(); %>

    <%
        songList = StoreSongLink.linkLis         


        

Answer 1

Your iteration is wrong in

for (ArrayList list : songList){}

songList contains the list of String elements not the list of ArrayList

so you need to iterate this way for (Object song: songList){}

or

ArrayList songList = new ArrayList();
for (String song: songList){}
