Question

I was asked this question in interview and can’t find a solution to it:

I have declared a list in my class. During its declaration, I haven’t
made it static. But after adding some data to it, I want to make it
static. Is it possible?

We are allowed to change the data type of the list.

Edit: Is it not possible to declare an array of static type and then convert the list to array and hence make it static?

Answer 1

Not using standard java, but you actually can manipulate the running byte code using a library such as Javassist; technically the answer is “yes”, but you may be shot by the team leader if you actually do this.
