Creating a fixed-size Stack

Question

I want to create a Stack in Java, but fix the size. For example, create a new Stack, set the size to 10, then as I push items to the stack it fills up and when it fills up t

Answer 1

Here is a SizedStack type that extends Stack:

import java.util.Stack;

public class SizedStack extends Stack {
    private int maxSize;

    public SizedStack(int size) {
        super();
        this.maxSize = size;
    }

    @Override
    public T push(T object) {
        //If the stack is too big, remove elements until it's the right size.
        while (this.size() >= maxSize) {
            this.remove(0);
        }
        return super.push(object);
    }
}

Use it like this: Stack mySizedStack = new SizedStack(10);. Other than the size, it operates like any other Stack.
