Question

I have a function that gets an int value from the user and assigns it to an int id.
I have a Paper class. So what I want to do is everytime I get value from user I want to create a Paper object with that name.

For eg.

// get value from user and assign it to int id;
id= 312;

// create Paper object with value from id
Paper (value of id) = new Paper();

Answer 1

Variable names are a compile-time thing; they don’t exist at run-time. You probably want to use something like a map:

Map<Integer,Paper> = new HashMap<Integer,Paper>();

...

map.put(id, new Paper());
