How to pass a stack from one activity to another in android studio

Question

I am trying to pass a stack from one activity to another in android studio.

Currently I have a stack called: Stack<Integer> teamAstack = new Stack<>();

And I am passing it like this:

                public void onClick(View view) {
                Intent intent = new Intent(MainActivity.this,GameReview.class);
                intent.putExtra("stack1",teamAstack);        
                startActivity(intent);
            }

From what I have looked online to pass objects I need to do it like this?

Receiving Activity

getIntent().getSerializableExtra("stack1");

I initially tried setting it equal to a new stack which I made in the new activity but it says the types are different, with one being a stack and the other being serializable. I am unsure what do to to pass the stack correctly so that I can start popping and pushing from the new activity, thanks for all your help! There was nothing specifically for stacks on all my searches which is why I am having this issue.

New Activity:

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

import java.util.Stack;

public class GameReview extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_game_review);

    Stack<Integer> stack11 = (Stack<Integer>)getIntent().getSerializableExtra("stack1");
    Stack<Integer> stack22 = (Stack<Integer>)getIntent().getSerializableExtra("stack2");

}
}

when you call getIntent().getSerializableExtra("stack1"); you get an object of type Serializable since you know this object is of type Stack<Integer> you can cast it and store it in a variable

Stack<Integer> stack = (Stack<Integer>)getIntent().getSerializableExtra("stack1");
