If you don't use generics, you can add any objects in ArrayList.

If you use the generic type Object (e.g. ArrayList<Object>) that's also possible.

possible, yes, but is it advisible ?

[Manish Singh]

why do you want to store different objects in the same list??

If you need a mixed-type collection you have little choice.

In practice you rarely need a mixed-type collection, and if you do, you should have a good look at the design of your application. To me, the need for a mixed-type collection sounds like a code smell. If you use such a collection, then somewhere in your code you're going to use ugly things like casts or the instanceof operator.

Dear All,

Could you please suggest me how we write the piece of code for the needful?

Thanks!

You might want to consider creating a new, purpose-built class for this problem.
