How can I handle errors in a stack implementation in Java?

You can handle errors in a stack implementation by using exceptions. For example, throw an exception when trying to pop from an empty stack.

What types of exceptions should I consider?

You should consider using custom exceptions like StackUnderflowException for popping from an empty stack and StackOverflowException for pushing to a full stack.

Can you show me a code example?

Sure! Here's a simple example:

class Stack {
    private int maxSize;
    private int[] stackArray;
    private int top;

    public Stack(int size) {
        maxSize = size;
        stackArray = new int[maxSize];
        top = -1;
    }

    public void push(int value) throws StackOverflowException {
        if (top == maxSize - 1) {
            throw new StackOverflowException("Stack is full");
        }
        stackArray[++top] = value;
    }

    public int pop() throws StackUnderflowException {
        if (top == -1) {
            throw new StackUnderflowException("Stack is empty");
        }
        return stackArray[top--];
    }
}

What if I want to implement a dynamic stack?

For a dynamic stack, you can use an ArrayList instead of a fixed-size array. This way, you can resize the stack as needed.
