Supposedly you want to create an object that dynamically takes object parameters and stores them in an ArrayList. All of the objects are of the same type and instead of creating a new array every time you use an ArrayList because you can keep on adding objects to it and it will still retain the order.
Now, suppose want to get an new array of the type of objects that you put in the ArrayList back. You can use ArrayList‘s toArray() method, and get an array of Object objects. Or you can use the following call:

MyObject [] objectArray = (MyObject[])theArrayList.toArray(new MyObject[0]);

Grizzly but true.

To compare the value of two strings in Java one would simply do:

string1.equals(string2)


Yet JSTL EL does not use the . notation the same way. Instead, JSTL actually works the right way:

<c:if test="string1 == string2" />
