如何在Java中创建多个堆栈

Question

I want to create many stacks using for or while but I don't have any idea.

Ex:

Stack<...> stack_1 = new Stack<>();
Stack<...> stack_2 = new Stack<>();
...
Stack<...> stack_n = new Stack<>();

Create as above is very slowly. So, I want to have an idea to create quickly many stack by for or while such as:

for (...) {
    Create stack(index) ...
}

Answer 1

List<Stack<Something>> stacks = new ArrayList<>(1000);
for (int i = 0; i < 1000; i++) {
   stacks.add(new Stack<Something>());
}
