Detailed explanation-1: -Pop operation refers to the removal of an element. Again, since we only have access to the element at the top of the stack, there’s only one element that we can remove. We just remove the top of the stack.
Detailed explanation-2: -It means insertion and deletion in the stack data structure can be done only from the top of the stack. You can access only the top of the stack at any given point in time. Inserting a new element in the stack is termed a push operation. Removing or deleting elements from the stack is termed pop operation.
Detailed explanation-3: -remove(int index) method is used to remove an element from a Stack from a specific position or index. Parameters: This method accepts a mandatory parameter index is of integer data type and specifies the position of the element to be removed from the Stack.
Detailed explanation-4: -pop() method in Java is used to pop an element from the stack. The element is popped from the top of the stack and is removed from the same.
Detailed explanation-5: -Pop Operation on Stacks: Accessing the content while removing it from the top of the stack, is known as a Pop Operation. In an array implementation of pop() operation, the data element is not actually removed, instead top is decremented to a lower position in the stack to point to the next value.
