I see that we cannot modify the String which lies inside an ArrayList<String>.
Can someone tell me why ?

Here is some code that attempts to do this (the wrong way)-

Because you can't change a String anywhere. They're immutable.

It doesn't matter whether it's in a List or not.

Your line s = s + " of steel!"; creates a new String and assigns it to s. The fact that the original reference pointed to a String you placed in a List is irrelevant.
