Java Data Structure #10

What I’ve Learned

First, determine whether it’s just Node or Node.value.

Disclaimer

For LeetCode, I started learning about data structures on Udemy. I’ve been studying with lecture named Java Data Structures & Algorithms + LEETCODE Exercises.

Stack: Push for a Stack That Uses an ArrayList

   public void push(T value){
        stackList.add(value);
    }

Stack: Pop for a Stack That Uses an ArrayList

   public T pop(){
        if(isEmpty()) return null;
        return stackList.remove(stackList.size()-1);
    }
