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

for (ArrayList list : songList){} // Error is here

And you have define a reference of ArrayList of Object type and declared a String type ArrayList instance which should be ArrayList songList = new ArrayList(); or ArrayList songList = new ArrayList(); (supports only java 7)

So the Corrected code could be like -

<%! List songList = new ArrayList(); %>
...
for (String list : songList){
}
